3. What computers will the Pro Audio Basic 16 work in?
The Pro Audio Basic 16 was designed around the IBM AT specification.  It 
will work in a 486/50 if the bus (I/O CLK) speed is lowered down to 8 
Mhz.  Please note that the bus speed is not the same as the CPU speed.  
The minimum requirements would be a 386 or higher processor.

4. How much disk space is required to load all of the files onto 
the hard drive?
About 5-6 megs for the Pro Audio Basic 16.

5. Can I have two sound cards in my computer?
No.  Other than specialized software that would be developed by an end 
user, there are currently no applications that will utilize more than one 
sound card at a time.  Please note that the only exception to this rule is if 
you are installing a wavetable upgrade card that was designed to enhance 
your current sound card.

6. My system files are not being updated after I run the 
installation program.  How do I fix this?
1.) At the DOS prompt, type:

SETVER C:\DOS INSTALL.EXE 6.00   [enter]

DOS will issue a long warning message about compatibility, and you may 
want to read it.

2.) REBOOT THE SYSTEM!  The change will NOT take effect until the 
system is restarted!

3.) Re-install your Media Vision software from floppy disk.  The 
installation  should now work.

4.)  Remove INSTALL.EXE from the SETVER list with the following 
command:

SETVER C:\DOS INSTALL.EXE /D   [enter]

Alternately, the computer could be booted from a DOS 5.0 or DOS 6.0 
bootable  diskette.

7. What are the changes that are made to my system after I 
install the software for my sound card?
Here are the changes that are made to your system files.

CONFIG.SYS

DEVICE=C:\PROAUDIO\MVSOUND.SYS D:5 Q:7 S:1,220,1,5 M:0 J:1

(Note:  If your computer uses a Phoenix or Award Bios, please add the 
following parameter to the end of the MVSOUND.SYS line:  "/W:0" )

AUTOEXEC.BAT

SET BLASTER=A220 D1 I5 T3

SYSTEM.INI

[386Enh]
device=vpasd.386
dmabuffersize=064

[mci]
CDAudio=mcicda.drv
mixer=mcimixer.drv

[drivers]
mixer=mvmixer.drv
timer=timer.drv
midimapper=midimap.drv
wave=mvproaud.drv
aux=mvproaud.drv
midi=opl3.drv
midi1=mvproaud.drv

[Multimedia.Setup]
audio=mvproaud.drv,0,0,0

[mvproaud.drv]
dma=5
irq=11

[opl3.drv]
drumchannel=10

8. Can I use the same DMA and IRQ values for both the Pro 
Audio Basic 16 and Sound Blaster emulation portions of the 
card?
You CANNOT use the same DMA and IRQ for the Pro Audio Basic 16 
and Sound Blaster emulation portions of the board.  The values MUST be 
different.

9. I've heard that I might have audio problems if I have a 
Symphony chipset on my motherboard.  Can this be 
corrected?
Yes.  You need to download SYMPFIX.EXE from the Media Vision BBS.  
Please follow the directions in the included text file.  If you have a 
Symphony chipset and you are not experiencing any sound problems, then 
you do not need the SYMPFIX patch.  Here is the DEBUG routine used in 
the SYMPFIX patch.  

DEBUG 			[enter]
O A8 05			[enter]
O A9 60 		[enter]
Q 			[enter]

10. Is the Pro Audio Basic 16 supported under UNIX?
Unfortunately, there is no support for the Pro Audio Basic 16 under UNIX.

11. What type of microphone will work with the Pro Audio Basic 
16?
The Pro Audio Basic 16 accepts dynamic microphones with impedance of 
600 to 20K Ohms.

12. What causes a Memory Parity error?
This is typically caused by a DMA conflict.  You will find the DMA 
parameter on the MVSOUND.SYS line in the CONFIG.SYS file.  The 
DMA is set with the D:x parameter.  Many times increasing the 
DMABUFFERSIZE in the [386Enh] section of the SYSTEM.INI file will 
resolve this problem.  Here is a sample line.

DMABUFFERSIZE=128

13. How do I edit my files?
You can use Notepad in Windows to edit your files.  You can also use the 
EDIT command under DOS.  You can also use the SYSEDIT program in 
Windows.  To use the SYSEDIT program in Windows:

1.)  Ensure that you are at your Program Manger.
2.)  Click on FILE under Program Manager.
3.)  Click on RUN
4.)  Enter the following on the command line:
SYSEDIT  [enter]
5.)  Edit the file.  When you are ready to save the file, click on FILE and 
then SAVE.
6.)  Click on FILE and then EXIT to exit the editor.

To use the EDIT program under DOS:

1.)  Enter the following at the DOS prompt:
CD\  [enter]
2.) Enter the following at the prompt:
EDIT  CONFIG.SYS  [enter]
3.)  Edit the file.  When you are ready to save the file, hold down [ALT] + 
[F].  Then, press [X] to exit.  You will be prompted to save the file.  When 
prompted to save the file, press [Y].

14. Can I load the Media Vision device driver high?
Yes.  The Media Vision device driver can be loaded into upper memory.  
Here is a sample line which loads MVSOUND.SYS into upper memory.

DEVICEHIGH=C:\PROAUDIO\MVSOUND.SYS  D:3  Q:7
15. When I boot my system or go into Windows, I get  read 
errors from my floppy drive.  What is happening?
Check your CONFIG.SYS and AUTOEXEC.BAT files for references to 
your floppy drives.  Unless you typically boot from your flopyy drive, none 
of your lines should try to load drivers or TSRs from the a floppy drive.  
Check the PATH statement in your AUTOEXEC.BAT file.  It is likely that 
you will find some reference to your floppy drive on this line.

16. After I installed your card, my modem stopped working.  Is 
this what is called an IRQ conflict?
Yes, this is an IRQ conflict.  It is likely that you are using IRQ 3 for your 
sound card as well as your modem.  You will need to stop using IRQ 3 for 
the sound card.  (NOTE****** Please see question # 17 regarding a possible 
CD-ROM interface on your PA Basic card.)  Here are some steps to assist you 
in finding a suitable IRQ.

Please make the following changes to your system files.

CONFIG.SYS

DEVICEHIGH=C:\PROAUDIO\MVSOUND.SYS D:3 Q:10 S:1,220,1,7 M:0 J:1

Make sure that these are the last two lines in your CONFIG.SYS file.

AUTOEXEC.BAT

SET  BLASTER=A220  D1  I7  T3

Test the DMA and IRQ settings by using PLAYFILE under DOS.

Use PLAYFILE under DOS to make sure that we are using a solid DMA 
channel. Make sure that your speakers or headphones are  plugged into the 
OUT jack on the back of the sound card.  Change directories to the Media 
Vision directory (PROAUDIO). Test the sound by entering the following 
line:  Please note that you may use something other than the TEST.WAV 
file to test your sound.


C:\PROAUDIO>PLAYFILE  TEST.WAV	 [enter]

You should hear the .WAV file play once.

If this does not sound normal, adjust the IRQ setting on the 
MVSOUND.SYS line in your CONFIG.SYS file.  Here is a sample line for 
your system.  Once you have sound under DOS, the Windows sound 
should follow.  Make sure that you are using the same DMA and IRQ 
settings under DOS and Windows.  The DMA and IRQ settings for 
Windows can be found in the [mvproaud.drv] section near the bottom of 
the SYSTEM.INI file.


17. Hey!  I bought a sound card without a CD-ROM interface, 
and now I see a header at the end of my card that looks 
supiciously like a CD-ROM interface.  Is this a CD-ROM 
interface on the end of my card?

Yes.  Due to popular demand, Media Vision has had to 
substitute a PAS 16 for the Pro Audio Basic 16 sound card.  The cards
are functionally identical in terms of performance.  The cards that are
being used as a substitute also have a CD-ROM interface located at the
end of the sound card.  You may have any of the following CD-ROM 
interfaces on the end of your card.

1.)  An interface for an Philips/LMSI 205 CD-ROM drive.  

This is a 15-pin proprietary CD-ROM interface.  If you ever decide
to hook up a CD-ROM drive to this card, the only drive you will be 
able to connect is the Philips CM 205 CD-ROM drive.  It would also
be a good idea for you to download FSEFAQ.EXE.  This is the FAQ 
for the Fusion CD 16 with LMSI CD-ROM drive.

2.)  An interface for a Sony CDU 31A CD-ROM drive.  

This is a 34-pin proprietary CD-ROM interface.  A Sony CDU 33A drive
will also operate on this interface.  You should download F31FAQ.EXE
for assistance with this configuration

3.)  A SCSI interface.  

This is a 50-pin SCSI interface.  This card is identical to the 
PAS 16 rev. D.  Download P16FAQ.EXE for the FAQ's on this card.

Please note that the LMSI CD-ROM drive uses an IRQ and an 
I/O address.  These values, the IRQ and I/O, are set by using jumpers
on the sound card.  The card is preset for IRQ 3 which will conflict with
another device that is trying to use IRQ3.  The device typically using IRQ 3
will be your modem.  The card is also preset to use an I/O of 340 which will 
conflict with another device that is trying to use an I/O adress of 340.

To correct this situation, all you need to do is remove the shunts
from jumper block J14 and J15 on the end of the sound card.  You 
should find these jumpers in the lower left hand corner of the sound
card.  Once the jumpers are removed IRQ 3 will be free.  There 
are no other jumpers on the card that you should have to move.  
Here are all of the settings for J14 and J15.


J14
=======
2   4   6   8
            +	pins and jumpers
1   3   5   7
=======
6   5   4   3	IRQ values

Pins 1 + 2 = IRQ 6
Pins 3 + 4 = IRQ 5
Pins 5 + 6 = IRQ 4
Pins 7 + 8 = IRQ 3  (default)
 

J15
=====
2   4   6	
+   +           pin and jumpers
1   3   5
=====

Pins 1 + 3 and 2 + 4 = I/O 340h  (default)
Pins 3 + 5 and 2 + 4 = I/O 330h
Pins 1 + 3 and 4 + 6 = I/O 310h
Pins 3 + 5 and 4 + 6 = I/O 300h

18. I've installed the card and software, but I do not get any 
sound under DOS or Windows.  What is happening?
Here are some suggestions that should help you sort out what is happening 
on your system.  The first thing you want to do is to make sure that the 
sound card is functioning under DOS.

Here is a sample configuration for your CONFIG.SYS file.

DEVICE=C:\PROAUDIO\MVSOUND.SYS D:5 Q:10 S:1,220,1,5 M:0 J:1 T:1 /W:0

Reboot the system.  Make sure that your speakers or headphones are 
plugged into the OUT jack on the back of the sound card.  Change 
directories to the Media Vision directory (PROAUDIO).  Test the sound by 
entering the following line:  Please note that you may use something other 
than the TEST.WAV file to test your sound.

PAS  RESET			[enter]
PLAYFILE  TEST.WAV		[enter]

You should hear the .WAV file play.  If you hear no sound, then enter the 
following at the DOS prompt:

DEBUG 				[enter]
O A8 05				[enter]
O A9 60 			[enter]
Q 				[enter]

Try the PLAYFILE command again.  If this now works, download 
SYMPFIX.EXE from the Media Vision BBS, and follow the directions in 
the included text file.

If this does not work, try a different DMA / IRQ combination.  Once there  
is sound in DOS, Windows should also have sound.  If you still have no 
sound  in Windows, then check to make sure that the DMA and IRQ 
settings match the D: and Q: parameters on the MVSOUND line.

You should also try the card in a different slot.  Make sure that the BUS 
speed on your system is set to 8.33 mhz.

19. None of my games work with sound.  What am I doing 
wrong?
The lack of sound is probably related to insufficient conventional memory 
for the program.

Consult your DOS manual regarding memory management.  The Media 
Vision drivers can load into upper memory without any problems. It is 
recommended that your conventional memory be at least 590 kb.  This 
should be adequate to run most applications.

If enough memory cannot be made available, you may need to create a 
boot disk, with a minimal number of drivers.

Finally, please refer to your instruction manual that came with the game.  
You may also find it helpful to contact the game manufacturer.

20. Why is my audio so noisy?
When used in computers having certain combinations of hardware 
(processor, BIOS, and chipset), the Pro Audio Basic sound cards can 
produce static, popping, and hiss.  There are several solutions available to 
you.

First, try adding a T:1 as well as a /W:0 to the end of the MVSOUND line 
in the CONFIG.SYS.  For example:

DEVICE=C:\PROAUDIO\MVSOUND.SYS D:3 Q:7 S:1,220,1,5 M:0 J:1 T:1 /W:0

Restart your computer, and see if the noise goes away.  If not, try adjusting 
your DMA settings.  You may want to switch to  16 bit DMA IRQ settings 
if you are currently using 8 bit DMA and IRQ settings.  If you are currently 
using  16 bit DMA and IRQ settings,  try dropping down to 8 bit DMA and 
IRQ settings.  It is recommended that you use the same DMA and IRQ 
setting for both DOS and Windows.  The DMA setting for Windows can 
be found near the bottom of the SYSTEM.INI file in the 
[MVPROAUD.DRV] section.  It is likely that the DMA change and the 
addition of the T:1 will eliminate the popping and static noise.  

You may also want to investigate your mixer settings.  Make sure that you 
do not have something turned up too much.  You can check the mixer 
settings by using the PAS utility under DOS.  If  you would like to reset 
the DOS mixer, you can type the following at a DOS prompt:

PAS RESET  [enter]

At the DOS prompt, type PAS *   [enter].
Under Windows use the Pocket Mixer to check your settings.

21. How do I save my volume settings?
Volume settings for the Pro Audio Basic 16 can be initialized when the 
computer starts up.  Here's how:

1) At the DOS prompt, type

PAS *  [enter]

2) Adjust the volume settings to the desired levels.

3) Hold down <SHIFT> and press the function key F5.  This saves the 
mixer settings under the F5 setting.  To test the procedure, press the F4 
key.  This will reset the mixer to the default volume levels.  Press the F5 
key, and your saved volume settings should be recalled.

4) Press the ESC key to exit the mixer.

5) Edit your AUTOEXEC.BAT file.

6) Check to see that the Media Vision directory is in the PATH statement.  
Add it if it isn't.

7) Add a new line UNDERNEATH your PATH statement:

PAS F5  (Note: you may also use: PAS SET F5)

8) Save the changes to the AUTOEXEC.BAT.  Reboot.  Your new volume 
levels should be automatically set every time you start the computer.

22. What do I need to do to get my joystick to work?
You need to turn the Joystick port "on" on the MVSOUND.SYS line.  
You will use the "J:x" parameter to do this.  Here is a sample line that has 
the game port turned "on."

DEVICE=C:\PROAUDIO\MVSOUND.SYS  D:3  Q:7  S:1,220,1,5  M:0 J:1

Here are some other tips that should ensure that your joystick port works.

1.)  Make sure that you have only 1 active game port on your system.  
Some motherboards have a built in game port.  You will need to disable the 
built in game port to use the game port on the sound card.  It does not 
matter which game port you use.   So, if you are unable to disable a game 
port already on the system, just disable the game port on the sound card.

"J:1" turns the joystick on.
"J:0" turns the joystick off.

2.)  Try turning the TURBO switch off on your PC.  

3.)  Try putting the card in a different slot.

4.)  Make sure that the BUS speed on your system is set to 8 mhz.

Some Hard drive controllers and motherboards may have a joystick port 
built into them.

Remove the sound card and connect the joystick to the Multi I/O card 
game port.  If it works the game port is NOT disabled.

Sometimes you will not be able to find the actual port that you would plug 
the Joystick into, however the interface may still be there and enabled!  
Look on all cards (including the mother board) for 16 pin header 
connectors with nothing plugged into them.  It is possible that this is a 
header connector for a joystick interface. 

Finally, you may need to reinstall your game to get the joystick recognized 
by the software.

23. What are the pinouts for the Joystick/Midi port?

1	+5VDC
2	JOYSTICK 1 FIRE 1
3	JOYSTICK 1 X
4	GROUND
5	GROUND
6	JOYSTICK 1 Y
7	JOYSTICK 1 FIRE 2
8	+5VDC
9	+5VDC
10	JOYSTICK 2 FIRE 1
11	JOYSTICK 2 X
12	MIDI OUT  (GROUND on MIDI Mate)
13 	JOYSTICK 2 Y
14	JOYSTICK 2 FIRE 2
15	MIDI IN (+5VDC on MIDI Mate)

24. Does the Pro Audio Basic 16 support dual joysticks?
The Pro Audio Basic 16 will not support dual joysticks in its current 
configuration.  Here are the pinouts to create a modified joystick to 
support a dual joystick.

(........) = no connection

If you have a Midimate, the Midimate joystick port will support dual 
joysticks.

25. What is a Midimate?
A Midimate is a device that will allow you to connect a music keyboard to 
your sound card.  The Midimate connects to the joystick/midi connector 
and your music keyboard.

26. Do you offer an upgrade policy?
Media Vision does not currently have an upgrade program.

27. Which jumpers on the sound card should I change?
None.

28. What does the MVSOUND.SYS statement do?
It initializes and enables the Pro Audio Basic 16 to produce sound under 
DOS.

29. How do I change the DMA and IRQ settings for the Pro 
Audio Basic 16 section of the card?
The DMA and IRQ settings for the sound card are software controllable.  
You will need to modify the D:# and Q:# parameters on the 
MVSOUND.SYS line in your CONFIG.SYS file. Please see "What are all 
of the switches for MVSOUND.SYS?" for even more information 
regarding the D:# and Q:#  parameters.  Here is a sample 
MVSOUND.SYS line.  In this example, the DMA will be 3 and the IRQ 
will be 7.

DEVICE=C:\PROAUDIO\MVSOUND.SYS D:3  Q:7  S:1,220,1,5 M:0 J:1

30. What are all of the switches for MVSOUND.SYS?
Options:
D:#	# = PAS DMA Channel		(default: 3)
Q:#	# = PAS IRQ Channel		(default: 7)
S:#	# = SB on/off,port,dma,irq	(default: 1,220,1,5)

31. What is the latest version of MVSOUND.SYS?
As of September 1994, the latest version of MVSOUND.SYS is 3.24.  The 
file is available on the BBS or Compuserve as MVSND324.EXE

32. How do I disable the Sound Blaster compatibility mode?
You will need to modify the MVSOUND.SYS line in your CONFIG.SYS 
file.  Here is a sample line with Sound Blaster emulation disabled.  Use the 
S:# parameter to enable or disable the Sound Blaster emulation.  Please see 
"What are all of the switches for MVSOUND.SYS?" for even more 
information regarding the S:# parameter.

DEVICE=C:\PROAUDIO\MVSOUND.SYS D:3 Q:7 S:0 M:0 J:1

33. How do I change the DMA and IRQ settings for the Sound 
Blaster section of the card?
You will need to modify the MVSOUND.SYS line in your CONFIG.SYS 
file. Use the S: parameter to configure the Sound Blaster emulation.  Here 
is a sample line with Sound Blaster emulation enabled using DMA 1, IRQ 
5, and I/O ADDRESS 220.  Remember that you must also modify the SET 
BLASTER statement in the AUTOEXEC.BAT file as well.

CONFIG.SYS

DEVICE=C:\PROAUDIO\MVSOUND.SYS  D:3  D:7  S:1,220,1,5  M:0 J:1

(Note: S:# = SB on/off,port,dma,irq)

AUTOEXEC.BAT

SET BLASTER=A220  D1  I5  T3

(Note: A=PORT  D=DMA  I=IRQ  T=Sound Blaster emulation mode)

34. What does the SET BLASTER statement do?
The SET BLASTER statement sets environment variables for the Sound 
Blaster emulation on your card that many multimedia applications need to 
function properly.

35. I just installed a CD-ROM drive that is supposed to work 
with your card, but the drive isn't working.  What do I do?
Here are some troubleshooting tips that should get your drive operational.

Make sure you have a LASTDRIVE statement in your CONFIG.SYS file:

LASTDRIVE=$

Where $ is at least one drive letter BEYOND the last physical drive on the 
system.

You will also want to make sure that you are using the latest version of 
MSCDEX.EXE on your system.  Here is a sample line for your 
AUTOEXEC.BAT file that will ensure that you are using the proper 
version of MSCDEX.EXE for you system.  Make sure that the 
MSCDEX.EXE line in the AUTOEXEC.BAT file is at the TOP of the file.    
Also, assign the drive letter to the CD-ROM drive with the /L parameter.

C:\DOS\MSCDEX.EXE /D:somename /M:10 /V /L:$

Where $ is the drive letter for the CD-ROM drive.  

If you are using DOS 5.00, the version that MSCDEX.EXE should report 
is 2.21.
If you are using DOS 6.00, the version that MSCDEX.EXE should report 
is 2.22.
If you are using DOS 6.20, the version that MSCDEX.EXE should report 
is 2.23.

36. What does the MSCDEX.EXE statement do?
MSCDEX.EXE is a TSR that is used in conjunction with a  CD-ROM 
driver.  MSCDEX stands for Microsoft CD Extensions.  MSCDEX is a 
DOS version sensitive program.  Here is a sample line for your 
AUTOEXEC.BAT file that will ensure that you are using the proper 
version of MSCDEX.EXE for your system.

C:\DOS\MSCDEX.EXE  /D:MVCD001  /M:10

If you are using DOS 5.00, the version that MSCDEX.EXE should report 
is 2.21.
If you are using DOS 6.00, the version that MSCDEX.EXE should report 
is 2.22.
If you are using DOS 6.20, the version that MSCDEX.EXE should report 
is 2.23.

37. My third party CD-ROM drive is not working.  What gives?
Here are some troubleshooting tips that should get your drive operational.

Make sure you have a LASTDRIVE statement in your CONFIG.SYS file:

LASTDRIVE=$

Where $ is at least one drive letter BEYOND the last physical drive on the 
system.

Try the following sample lines in place of your current lines in the 
CONFIG.SYS file.

DEVICE=C:\PROAUDIO\MVSOUND.SYS D:5 Q:11 S:1,220,1,5 M:0 J:1 /W:0

You will also want to make sure that you are using the latest version of 
MSCDEX.EXE on your system.  Here is a sample line for your 
AUTOEXEC.BAT file that will ensure that you are using the proper 
version of MSCDEX.EXE for you system.  Make sure that the 
MSCDEX.EXE line in the AUTOEXEC.BAT file is at the TOP of the file.  
Also, assign the drive letter to the CD-ROM drive with the /L:$ parameter.

C:\DOS\MSCDEX.EXE /D:MVCD001 /M:10 /V /L:$

Where $ is the drive letter for the CD-ROM drive.  

If you are using DOS 5.00, the version that MSCDEX.EXE should report 
is 2.21.
If you are using DOS 6.00, the version that MSCDEX.EXE should report 
is 2.22.
If you are using DOS 6.20, the version that MSCDEX.EXE should report 
is 2.23.

38. How do I get CD audio from my third party CD-ROM drive?
You will need to contact a company by the name of TTS.  TTS is not 
affiliated with Media Vision.  TTS will be able to provide you with the 
appropriate audio cable necessary to connect any CD-
ROM drive to your Pro Audio Basic 16.  Here are the telephone and fax 
numbers for TTS.

Voice	800 - 887 - 4968
Voice	408 - 982 - 0653
FAX	408 - 982 - 0738

39. How do I increase the performance of my CD-ROM drive?
Here are some tips on possible ways to increase CD-ROM performance:

1) Increase M-parameter (memory buffers) on MSCDEX.EXE (32 is max.)
2) Use Expanded memory, and the /E switch on MSCDEX (only on 
certain computers.)
3) Try use the CD-ROM caching feature contained in SMARTDRV that 
comes with DOS 6.2.  CD-ROM caching is a feature of SMARTDRV
that comes with DOS 6.2.  To ensure that SMARTDRV is caching
your CD-ROM drive, make sure that you do not have the /U switch on
your SMARTDRV line. 

40. What will decrease the performance of my CD-ROM drive?
In general, here are some things that reduce CD-ROM performance:

1) Loading MSCDEX into high memory (most common)
2) Incorrect MSCDEX for your DOS version (common)
3) Using Expanded memory , and the /E switch on MSCDEX (only on 
certain computers)
4) Sound card conflicts (DMA, IRQ, or port address)
5) Loading CD-ROM driver into high memory (uncommon)
6) Using the CD-ROM caching that defaults with SMARTDRV that 
comes with MS-DOS 6.2.  To disable the caching feature, add the 
/U switch on your SMARTDRV line.

41. What is Wavetable synthesis?
Wavetable synthesis uses a digital recording samples of real instruments to 
play MIDI music.

42. Is my card wavetable upgradeable?
The  Pro Audio Basic 16 is not Waveblaster upgradeable.  The Pro Audio 
Basic 16 lacks the headers necessary to connect a wavetable add-on card.  

However, Media Vision's new Premium 3-D sound cards are wavetable 
upgradeable.  The Premium  3-D cards are 100% Waveblaster compatible.  
Media Vision sells the Korg Wavetable daughterboard to upgrade the 
Premium 3-D card to a Pro 3-D card.

Media Vision is aware of third party devices that will add wavetable 
capabilities to cards that are not Waveblaster upgradeable; however, Media 
Vision is unable make recommendations regarding third party devices.

43. What is the KORG wavetable upgrade?  Will it work on my 
system?
The KORG wavetable upgrade card is a Waveblaster compatible card.  As 
long as your card is Waveblaster compatible, the KORG card will work on 
your system.

44. What are the features of the KORG wavetable upgrade 
card?
  General MIDI compatible
  WaveBlaster compatible feature connector
  32 voice polyphony (simultaneous notes)
  16 part multitimbral (16 instruments at once)
  4Mb of sample ROM containing: 
  	128 musical instruments
  	4 drum set/effects of 47 instruments each
  32 oscillators
  32 dynamic digital low-pass filters
  Onboard DSP provides Reverb and Chorus effects.

45. I am getting "ADLIB is already in use" errors when I try to 
run my DOS applications through Windows.  How do I get 
rid of this error message?
If you are getting this type of an error, you are loading unnecessary drivers 
when you load Windows.  Check your SYSTEM.INI file for any of the 
following drivers.  If you find any of these, please remark them out with 
semi-colons (;;).  These lines will reside in the [386Enh] section of your 
SYSTEM.INI file.

DEVICE=VADLIBD.386
DEVICE=VSBD.386
DEVICE=VSBPD.386
DEVICE=VSGLX16.386
DEVICE=VSGLD.386
DEVICE=VSGD.386
DEVICE=VSGLX.386

46. I am getting the following error message, "Can't find ver. 
2.00 of VDMAD.386."
Some Windows applications replace this driver by their own DMA driver.  
To correct this problem, you need to edit your SYSTEM.INI file.  Look in 
the [386Enh] section for the following line:

DEVICE=VDMADX.386

Comment this line out of your file with semi-colons (;;).

;; DEVICE=VDMADX.386

Then, add the following statement to the very beginning of the [386Enh] 
section:

DEVICE=*VDMAD

Restart Windows.  The error message should disappear.

47. Why is Windows making this annoying looping sound when 
Windows first starts?
You are having an IRQ conflict.  You should be able to resolve this quite 
easily.  Please make the following changes to your system files, and you 
should be fine.

CONFIG.SYS

DEVICEHIGH=C:\PROAUDIO\MVSOUND.SYS  D:3  Q:12  S:1,220,1,7 M:0 J:1

Test the DMA and IRQ settings by using PLAYFILE under DOS.

Use PLAYFILE under DOS to make sure that we are using a solid DMA 
channel. Make sure that your speakers or headphones are  plugged into the 
OUT jack on the back of the sound card. Please note that you may use 
something other than the TEST.WAV file to test your sound.  Change 
directories to the Media Vision directory (PROAUDIO).  Test the sound by 
entering the following line:


C:\PROAUDIO>PLAYFILE  TEST.WAV	 [enter]

You should hear the .WAV file play once.

If this does not sound normal, adjust the IRQ setting on the 
MVSOUND.SYS line in your CONFIG.SYS file.  Here is a sample line for 
your system.  Once you have sound under DOS, the Windows sound 
should follow.  Make sure that you are using the same DMA and IRQ 
settings under DOS and Windows.  The DMA and IRQ settings for 
Windows can be found in the [mvproaud.drv] section near the bottom of 
the SYSTEM.INI file.

48. I am getting an error message stating that I need to "load 
Multimedia Extensions" before I run the installation 
program.  How do get rid of this message?
Before you can successfully install the Window drivers, you need to edit 
your SYSTEM.INI (in the Windows directory).  Look in the [boot] 
section, and locate a line that looks like this:

DRIVERS=MMSYSTEM.DLL

If this line is gone, add it.  If there is anything else on the end of this 
line, put two semi-colons in front of the whole line.  Here is an example:

;; DRIVERS=MMSYSTEM.DLL POWER.DRV


Add a new line right below the original, and make it look just like the first 
sample line above.  Save the file; re-boot Windows.  Now you can run the 
installation.  After it has completed, remove the new line, and remove the 
semi-colon on the original.

49. MIDI doesn't work on my system.  How do I configure the 
Midimapper?
1) Double-click on Control Panel (in the Main group).
2) Double-click on MIDIMAPPER.
3) Click on NEW.  A dialog box will come up.
4) Enter "Music1" in the name field.
5) Click on OK.  A grid will now come up.
6) In the center column, titled "PORT NAME," click once on [None] to  
bring down a list of available MIDI sound sources.
7) Select "MVI OPL3 FM Synthesizer."  This selection uses the sound 
card to create the MIDI sound for MIDI channel 1.
8) Repeat steps 6 and 7 for MIDI channels 1-10, and 13-16.
9) In the second column, titled "DEST Channel," click once on channel 
16.  
10) Using the up and down arrows, change this to 10.  This maps Source 
Channel 16 to Destination Channel 10 (for percussion).
11) Click on OK.  When prompted to save the changes, click on YES.
12) Click on the CLOSE button located near the right of the screen.

50. Ever since I installed your card, Windows locks up when I 
try to exit.  What is happening?
When exiting Windows, a .WAV file is trying to play.  The sound card is 
not able to play the .WAV file, and at this point, the computer is waiting 
for the file to be played.  It is likely that you are having an IRQ or DMA 
conflict.  Here are some troubleshooting tips that should help you solve this 
problem.  Here is a sample line for your CONFIG.SYS file.

CONFIG.SYS

DEVICE=C:\PROAUDIO\MVSOUND.SYS D:5 Q:11 S:1,220,1,5 M:0J:1 T:1 /W:0

You should first determine that you do not have an IRQ conflict.  You will 
want to test the IRQ values under DOS.  Here is a simple test that will tell 
us whether or not we have a solid IRQ setting.

Reboot the system.  Make sure that your speakers or headphones are 
plugged into the OUT jack on the back of the sound card.  Change 
directories to the Media Vision directory (PROAUDIO).  Test the sound by 
entering the following line:  Please note that you may use something other 
than the TEST.WAV file to test your sound.

PAS  RESET		[enter]
PLAYFILE  TEST.WAV	[enter]

You should hear the sound of a phone dialing.  If you hear no sound, then 
enter the following at the DOS prompt:

DEBUG			[enter]
O A8 05			[enter]
O A9 60			[enter]
Q			[enter]

Try the PLAYFILE command again.  If this now works, download 
SYMPFIX.EXE from the Media Vision BBS, and follow the directions in 
the included text file.

If this does not work, try a different DMA / IRQ combination.  Once there  
is sound in DOS, Windows should also have sound.  If you still have no 
sound  in Windows, then check to make sure that the DMA and IRQ 
settings for Windows match the D: and Q: parameters on the MVSOUND 
line.  You will find the DMA and IRQ settings near the bottom of your 
SYSTEM.INI file for Windows.  Here are the changes that should have 
been made to your SYSTEM.INI.


SYSTEM.INI

[386Enh]
device=vpasd.386
dmabuffersize=064

[mci]
CDAudio=mcicda.drv
mixer=mcimixer.drv

[drivers]
mixer=mvmixer.drv
timer=timer.drv
midimapper=midimap.drv
wave=mvproaud.drv
aux=mvproaud.drv
midi=opl3.drv
midi1=mvproaud.drv

[Multimedia.Setup]
audio=mvproaud.drv,0,0,0

[mvproaud.drv]
dma=x	    (this is the D: value on the MVSOUND.SYS line in the 
CONFIG.SYS)
irq=y	    (this is the Q: value on the MVSOUND.SYS line in the 
CONFIG.SYS)

[opl3.drv]
drumchannel=10


If changing the values for the DMA and IRQ settings do not help, please 
download the following file from the BBS.

GWPATCH.EXE

GWPATCH.EXE is a file that contains a different mix of Windows drivers 
that will often solve Windows lock ups.

GWPATCH.EXE contains the following files:

File: MVMIXER.DRV
Size: 41200
Date: 09-21-93
Time: 2:14p

File: MVPROAUD.DRV

51. I am getting the error message "can not successfully 
register the server" when attempting to access any of the 
Pocket Tools in Windows. How do I correct this problem?
The problem can be traced to a corrupted REG.DAT file in the 
WINDOWS directory.

According to the Windows Resource Guide, to restore the database, the 
following must be done:

1. Quit Windows, delete REG.DAT, and then restart Windows.

2. Run Registration Info Editor (REGEDIT.EXE from the Windows 
directory--great icon), which  will display an empty list of registered file 
types.

3. Choose "Merge Registration File" from the File menu.

4. Select "SETUP.REG" (WINDOWS\SYSTEM directory) from the File 
Name list in the dialog box and click the OK button.

This will restore the original Windows Registration Database.

52. Why do all of  my sounds play fast?  It sounds like my card 
is chipmunking.
It is likely that you have a DMA conflict.  Here are some troubleshooting 
tips that should help us figure out what is happening.  Remember that you 
cannot use the same DMA and IRQ for the Pro Audio Basic 16  and Sound 
Blaster emulation portions of the board.

Reboot the system.  Make sure that your speakers or headphones are 
plugged into the OUT jack on the back of the sound card.  Change 
directories to the Media Vision directory (PROAUDIO).  Test the sound by 
entering the following line:  Please note that you may use something other 
than the TEST.WAV file to test your sound.

PAS  RESET			[enter]
PLAYFILE  TEST.WAV		[enter]

You should hear the .WAV file play once in a normal speed.

If this does not sound normal, adjust the DMA setting on the 
MVSOUND.SYS line in your CONFIG.SYS file.  Here is a sample line for 
your system.

DEVICE=C:\PROAUDIO\MVSOUND.SYS  D:3  Q:7  S:1,220,1,5  M:0 T:1

If the sound is fine, please ensure that the DMA you are using under 
Windows matches the DMA you are using under DOS.  Here is a copy of 
what your SYSTEM.INI file should look like as far as Media Vision 
drivers are concerned.  You should notice that the DMA setting is at the 
bottom of your SYSTEM.INI in the [mvproaud.drv] section.

[386Enh]
device=vpasd.386
dmabuffersize=064

[mci]
WaveAudio=mciwave.drv
Sequencer=mciseq.drv
mixer=mcimixer.drv

[drivers]

53. Pocket CD won't work.  I am getting the following error 
message.  "There is an undetectable problem in loading the 
specified device driver."
First, make sure that you have a music CD in the drive before and when 
you launch PocketCD.  If not, you will get this error every time.

If you do have a music CD in the drive, and still get the error, you will 
need to:
1) Go to the Control Panel (in Main).
2) Open DRIVERS, and look for [mci] CD Audio.  Double-click on this.
3) If you get a "One CD-ROM found" message, restart Windows, and try 
PocketCD again.  If there is no message, you will need to make sure your 
CD-ROM driver is loading in DOS.

4) You may need to delete and then reinstall the [mci] CD Audio driver.  
This is a Microsoft driver.  Once you have replaced the [mci] CD Audio 
driver and if PocketCD is still not working, you need to exit Windows and 
shut the system down.  Restart your system, and try PocketCD one more 
time.

5.)  Make sure that you are using the proper version of MSCDEX for your 
system. MSCDEX stands for Microsoft CD Extensions.  MSCDEX is a 
DOS version sensitive program.  Here is a sample line for your 
AUTOEXEC.BAT file that will ensure that you are using the proper 
version of MSCDEX.EXE for your system.

C:\DOS\MSCDEX.EXE  /D:somename  /M:10

If you are using DOS 5.00, the version that MSCDEX.EXE should report 
is 2.21.
If you are using DOS 6.00, the version that MSCDEX.EXE should report 
is 2.22.
If you are using DOS 6.20, the version that MSCDEX.EXE should report 
is 2.23.

Finally, update your CD-ROM driver, (if available), since this can also 
create an error with PocketCD.

54. I am unable to use the Media Player in Windows to play 
audio CDs.  How can I correct this problem?
If you do not have an option for CD Audio with Media Player, then you 
will need to edit the MPLAYER.INI file for Windows.  You can use 
Notepad to edit the file.  All you need to do is make sure that you have the 
following line in the [Devices] section.

[Devices]
CDAudio=17,  CD Audio

55. I am only getting sound from one channel when playing a 
music CD.
The only driver that affects CD Audio is the [mci] CD Audio driver.  This 
is a Windows driver.  It has no affect on the CD-ROM drive under DOS, 
so for trouble shooting purposes, we should find out whether or not you 
are receiving Stereo CD Audio while under DOS.  To test this, you need to 
use the MUSICBOX.EXE  utility.  MUSICBOX should be in your 
PROAUDIO directory.  Start Musicbox.  Press "P" for Play.  You should 
start hearing CD-Audio.  You can press the <ESC> key to exit the 
program.  The CD-ROM drive will continue to play the disc.  At your DOS 
prompt type the following command.

PAS  RESET	 [enter]

If you now start hearing Stereo sound, then your mixer was out of 
adjustment.

If your drive has a headphones jack, try plugging the speakers or a set of 
headphones into the headphones jack on the CD-ROM drive.  If you still 
do not hear Stereo, then the drive is malfunctioning.

If you hear Stereo out of the headphones jack, then the problem is probably 
with the audio cable itself or its connection to the sound card.  Double 
check all of your connections.  If it is SAFE to operate your PC with the 
cover off, you might try to GENTLY wiggle the audio cable at each end.  
You may just have a bad connection. 

If it can be determined that the audio cable is good, then the sound card is 
going to be the source of the trouble.

If Musicbox works fine, then you should check the Pocket Mixer in 
Windows.  If the Pocket Mixer is set properly, then you should reinstall the 
[mci] CD Audio driver.  You will find the driver in the Drivers Applet 
under Control Panel.  Once you have replaced the [mci] CD Audio driver 
and  if the Windows CD player is still not working properly, you need to 
exit Windows and shut the system down.  Restart your system, and try the 
player one more time.

56. Is there a software developer's kit available for the Pro 
Audio Basic 16?
Yes,  please contact the Media Vision Sales department to purchase the 
SDK.  You can reach the Sales Department at 800-845-5870.

57. How do I get TBPRO to work?  It used to work fine, but it 
doesn't work anymore.
Here are some trouble shooting tips that should allow you to use TBPro.  
Please be aware that some of the versions of TBPro that Media Vision 
ships is an 8 bit version.

1.)  Use an 8 bit DMA.  Here are some sample lines for your 
CONFIG.SYS and AUTOEXEC.BAT files.

CONFIG.SYS

DEVICE=C:\PROAUDIO\MVSOUND.SYS  D:3  Q:5  S:1,220,1,7  M:0 J:1

AUTOEXEC.BAT

SET BLASTER=A220  D1  I7  T3

2.)  Use TBCONFIG.EXE to reconfigure TBPro.  Try reducing the 
sampling rate.  You might also try turning the Graphics mode OFF.

3.)  There is an updated version of TBPro on the BBS.  This version 
supports the usage of 16 bit DMA's.  The filename is TBPRO.EXE

58. I am getting the following error message when I use 
RECFILE.  "File is full or blocked."I am also not able to 
record 16 bit files.  What is happening here?
This problem is caused by slow system throughput.  To correct this,please 
try the following:

1.)  Reduce to a generic CONFIG.SYS and AUTOEXEC.BAT.

2.)  Make sure that your hard disk has been optimized (defragmented).  If 
you are using some kind of compression, like stacker, then it is very likely 
that you will not be able to record at the higher levels like 44khz because it 
uses so much disk space, you'll need something like 10 megs of 
unfragmented disk space, stacker causes the disk to be fragmented, so 
RECFILE won't work with the higher settings.

3.)  Try a lower sampling rate or try recording to a ramdrive.

59. Why am I getting a GPF (General Protection Fault) in 
"user.exe" when I try to use Pocket Recorder?
If you are unable to record, you may have to "reset" the Pocket Recorder 
section of your WIN.INI file before the Pocket Recorder will start working 
again.  Here is how you would "reset" the section.

1.)  Edit the WIN.INI file.

2.)  Find the section labeled:  [Media Vision Pocket Recorder]

3.)  Highlight (select) the entire section with your mouse.  Make sure that 
you ONLY select the [Media Vision Pocket Recorder] section.

4.)  Press the DELETE key.  This will remove the entire section.  

5.)  Save the WIN.INI.

6.)  Exit Windows.

7.)  Restart Windows.  Try the Pocket Recorder.
