3. What computers will the Pro Sonic 16 work in?
The Pro Sonic 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 2 megs for the Pro Sonic 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. Is there a software developer's kit available for the Pro 
Sonic 16?
Yes,  please contact the Media Vision Sales department to purchase the 
SDK.  You can reach the Sales Department at 800-845-5870.

7. Can I use the same DMA and IRQ values for both the Pro 
Sonic 16 and Sound Blaster emulation portions of the card?
You can use the same DMA and IRQ for the Pro Sonic 16 and 
Sound Blaster emulation portions of the board.  The DMA values 
can be different if you like.

8. How many IRQ's and DMA's will the Pro Sonic 16 occupy on 
my system?
The Pro Sonic uses 1 IRQ and 2 DMA's.  The MPU-401 emulation also 
requires a port address and IRQ if enabled.  All values are assigned via
software switches on the PROS.SYS line in the CONFIG.SYS file.
Please see questions 38 - 40 for more information on PROS.SYS.

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

10. What emulation modes does the Pro Sonic 16 card offer?
Both Sound Blaster and Sound Blaster Pro are supported.

11. How is Sound Blaster Pro emulation attained?
The Pro Sonic 16 uses the Media Vision JAZZ Digital to Analog
Converter (DAC) chipset to emulate the Sound Blaster Pro 
sound card.

12. How is Sound Blaster emulation attained?
The Pro Sonic 16 uses the Media Vision Thunderboard DAC
chipset to emulate the Sound Blaster original sound card.

13. What does the Pro Sonic 16 card use as a FM chip?
The Pro Sonic 16 uses the Yamaha OPL-3 FM chipset.

14. Is the Pro Sonic 16 supported under OS/2?
The Pro Sonic 16 is not supported under OS/2 ver. 2.21

15. Is the Pro Sonic 16 supported under UNIX?
Unfortunately, there is no support for the Pro Sonic 16 under UNIX.

16. What causes a Memory Parity error?
This is typically caused by a DMA conflict.  You will find the DMA 
parameter on the PROS.SYS line in the CONFIG.SYS file.  The 
DMA is set with the Hx 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

17. 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].

18. What are the changes that are made to my system after I 
install the Pro Sonic 16 card?

[pros401.drv]
port=330
int=2

[prosfm]
drumchannel=10

19. Can I load the Pro Sonic 16 device drivers high?
Yes.  The Pro Sonic 16 device drivers can be loaded into upper memory.
Here is a sample line which loads PROS.SYS into upper memory.

DEVICEHIGH=C:\PROSONIC\PROS.SYS  A220 I7 D1 E5 Q2 T330 V

Here is sample line that loads MSCDEX.EXE into upper memory.

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

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

21. Which jumpers on the sound card should I change?
There are three jumpers which you should might need to 
move on the card.

1.)  The joystick port is configured via the DISJS jumper on the sound card.
If the jumper is OPEN, the joystick port is enabled. 

2.)  The MPU 401 emulation is configured via the DISMPU jumper.  If the
jumper is OPEN, then MPU-401 is enabled.

3.)  J6 is used to set the port address for a Panasonic CD-ROM drive.
The default is port address 340h.  Here are all of the possible port address
settings:

Pins 5+6	Pins 3+4	Pins 1+2	I/O
==================================================
ON		ON		ON		300h
ON		ON		OFF		310h
ON		OFF		ON		320h
ON		OFF		OFF		330h
OFF		ON		ON		340h default

22. 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 floppy drive, none
of your lines should try to load drivers or TSRs from 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.

23. Why am I getting an "Incorrect DOS Version" error 
message?
This error message is coming from the MSCDEX.EXE line in the 
AUTOEXEC.BAT file.  MSCDEX.EXE is a TSR that is used in 
conjunction with a  CD-ROM drive.  

If you do not have a CD-ROM drive, you can eliminate this line from
your AUTOEXEC.BAT file.

MSCDEX stands for Microsoft CD Extensions.  MSCDEX is a DOS 
version sensitive program. If you do have a CD-ROM drive, then here are 
the steps that you would take to resolve the problem.

1.)  Use the MSCDEX.EXE from the DOS directory.   Here is a sample 
line.

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.

2.)  Assign the drive letter to the CD-ROM drive (on the MSCDEX line in 
the AUTOEXEC.BAT) with the /L:$  parameter where $ is the drive letter
for the CD-ROM drive.  In our example, the CD-ROM drive is going to 
be drive D.  Here is a sample line.

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

3.)  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.  Again, in our example  the CD-ROM drive letter is D.
So, the sample line is:

LASTDRIVE=E

24. How do I correct a "not enough driver letters" error 
message?
You will want to make the following changes to correct this error.

1.)  Assign the drive letter to the CD-ROM drive (on the MSCDEX line in 
the AUTOEXEC.BAT) with the /L:$  parameter where $ is the drive letter
for the CD-ROM drive.  In our example, the CD-ROM drive is going to 
be drive D.  Here is a sample line.

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

2.)  Make sure you have a LASTDRIVE statement in your CONFIG.SYS 
file.  The LASTDRIVE must equal at least one drive letter BEYOND
the last physical drive on the system.  Again, in our example  the 
CD-ROM drive letter is D.  Here is a sample line:

LASTDRIVE=E

25. 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:\PROSONIC\PROS.SYS  A220 I7 D1 E5 Q2 T330 V

Here is a sample configuration for your AUTOEXEC.BAT file:

SET BLASTER=A220 I7 D1 H5 T4

It is imperative that you have a SET BLASTER line in your AUTOEXEC
file.

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 (PROSONIC).  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.

PLAYFILE  TEST.WAV		[enter]

You should hear the .WAV file play.  If you hear no sound, reverse the 
thumbwheel on the back of the card.  Try PLAYFILE again.

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 I parameters on the PROS 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.

26. 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.  Here are 
some steps to assist you in finding a suitable IRQ.

Please make the following changes to your system files.

CONFIG.SYS

DEVICE=C:\PROSONIC\PROS.SYS P220 I7 D1 E5 T330 V

AUTOEXEC.BAT

SET  BLASTER=A220 I7 D1 H5 T4

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 (PROSONIC). 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:\PROSONIC>PLAYFILE  TEST.WAV	 [enter]

You should hear the .WAV file play once.

If this does not sound normal, adjust the IRQ setting on the 
PROS.SYS line in your CONFIG.SYS file.  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 
[pros.drv] section near the bottom of the SYSTEM.INI file.

27. 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.

28. What do I need to do to get my joystick to work?
The joystick port is configured on the sound card with the DISJS
jumper.  If jumper DISJS is OPEN, the joystick port is enabled.  

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.

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.

29. What are the pin outs 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

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

31. 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.

32. How is the MPU 401 emulation enabled on the Pro Sonic?
MPU-401 emulation is enabled / disabled via the DISMPU jumper.
If DISMPU is OPEN, then MPU-401 emulation is enabled.  You also assign
an I/O address and an IRQ on the PROS.SYS line in the CONFIG.SYS file.

Use the T and Q parameters to do this.  See question # 40 for more information
on the T and Q parameters.

33. 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.

41. How do I change the DMA and IRQ settings on the Pro 
Sonic 16?
The DMA and IRQ settings for the sound card are software controllable.  
You will need to modify the D#, E# and I# parameters on the 
PROS.SYS line in your CONFIG.SYS file. Please see "What are all 
of the switches for PROS.SYS?" for even more information 
regarding the D#, E#. and I# parameters.  Here is a sample 
PROS.SYS line.  In this example, the 8-bit DMA will be 3,

Blaster emulation on your card that many multimedia applications need to 
function properly.

43. Can I have more than one SCSI host adapter in my system?
Yes.  You can have as many SCSI host adapters in the same system as 
there are available slots.  The Pro Sonic 16 does not use a SCSI host
adapter.  The CD-ROM adapter on the card should not interfere 
with other SCSI host adapters on your system.

44. Can I connect a SCSI device to the Pro Sonic 16?
The card that came in your kit uses a proprietary CD-ROM connector.
It is not a SCSI host adapter, so unfortunately, you will not be able to 
use the sound card as a host adapter for SCSI devices.

45. Can I connect any CD-ROM drive to the CD-ROM controller 
on my card?
You can only connect a Panasonic CR 563-B CD-ROM drive to the controller on the Pro Sonic 16.  

However, you can connect the CD-audio output from any CD-ROM
drive to the Pro Sonic 16 as long as you have the appropriate audio 
cable.  You would only need to make this connection if you plan on 
using the mixer on the sound card to control CD-Audio.  You can 
purchase an Audio cable for your CD-ROM drive and sound card 
from TTS. The telephone and fax numbers for TTS are:

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

46. What type of CD-ROM adapter is on the end of my card?
The adapter used on the Pro Sonic 16 is for a Panasonic CR 563-B CD-ROM drive.

47. Where do I get the drivers for the Panasonic CD-ROM drive?
Due to contractual reasons, Media Vision is unable to provide the 
CD-ROM drivers for the Panasonic CD-ROM drives.  You will 
need to contact Reveal for the drivers for the Panasonic CD-ROM 
drive.  Here is the BBS number for Reveal.

BBS:		(818)718-8188

You will need to download the SGCDU.SYS driver from the Reveal
BBS.  Once you have the file in your PROSONIC directory, here are 
the lines that you will need to add to your CONFIG.SYS and 
AUTOEXEC.BAT files to get your drive functioning.

Add the following line at the bottom of your CONFIG.SYS

DEVICE=C:\PROSONIC\SGCDU.SYS /D:MVCD001 /P:340 /N:1

Where:
/D:MVCD001	Specifies the device name.
/P:340		Specifies the port address used by the CD-ROM drive.
/N:1		Specifies the number of CD-ROM drives attached to the
		card.  Without this parameter, you may find that you have 
		4 CD-ROM drives attached to the card.

The port address is assigned on the sound card via J6.
Here are all of the possible settings for J6.

Pins 5+6	Pins 3+4	Pins 1+2	I/O
=================================================
ON		ON		ON		300h
ON		ON		OFF		310h
ON		OFF		ON		320h
ON		OFF		OFF		330h
OFF		ON		ON		340h default

Add the following line to the top of your AUTOEXEC.BAT:

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

48. I am getting CDR 101 errors.  What can I do to fix this?
Troubleshoot  your CD-ROM drive while in DOS. A CDR 101 error is a 
very difficult error to troubleshoot via FAQ.  Here are all of the possible 
trouble shooting tips that will either eliminate the problem, or at least 
narrow it down.  The PC is assuming that the driver is loaded properly, but 
the CD-ROM drive is having problems reading the disk.  Please try the 
following.

1.) Make sure that you are not trying to read an audio disc.

2.)  Check the internal flat ribbon cable.  Disconnect and 
reconnect the ribbon cable that connects the CD-ROM drive
to the interface card.  Do this at both ends of the cable.  Try a 
different or new ribbon cable.  It is possible that the cable is bad.
If the cable is correctly connected to the card, it is 
possible that it is plugged in backwards on the CD-ROM drive.  In most 
cases the drive's connector is "keyed" so the cable cannot be put on wrong, 
however, it may be possible to force the cable on incorrectly.  Check the 
cable for damage, kinks, or being stretched to the maximum length.
Make sure the ribbon cable is seated completely.  When 
you re-install the cable, check for bent pins; also, check the cable 
to make sure that it is not off-set where it is not covering all of 
the pins.

3.)  Make sure there is a LASTDRIVE statement in the CONFIG.SYS and 
that it is high enough to cover the CD-ROM drive plus one drive.  In other 
words, if the CD-ROM drive is drive E, then the statement should read as 
follows:

LASTDRIVE=F

This is a requirement of MSCDEX.EXE.  You don't need a LASTDRIVE 
statement if the CD-ROM drive is drive D.

4.)  The CD-ROM driver should ideally be located at the bottom of the 
CONFIG.SYS file.  Very rarely should it be at the top of the file.  If the 
CD-ROM driver loads first, it's possible to cause other problems.  As a 
test, move the CD-ROM driver to the top of the 
CONFIG.SYS file.  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.

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

Where $ is the drive letter for the CD-ROM drive.  This is where you will 
assign the drive letter to 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.

If you have run Memmaker and it has put memory locations at the front of 
the CD-ROM driver lines, please remove the memory locations.  Here is a 
sample line that loads the MSCDEX.EXE driver high without the memory 
location.

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

5.)  If your drive uses a caddie, make sure the caddie lid is closed.  Make 
sure the metal door on the caddie will move smoothly to the left or right, as 
well as return freely to the center.  Try a different caddie.  Make sure the 
CD is not skewed in the drive bay or in the CD caddie.  Confirm that the CD
is not up-side down.  In the drive bay, you can read the label of the CD 
when the drive door is open.  With a caddie, you can see the label of the 
CD through the clear plastic.

Remove the CD from the CD-ROM drive; replace it with a different CD, 
or use a replacement of the original CD.  See if the same error occurs.  If 
there are no more errors, then the first CD was bad.  If it continues with 
the same problem, then something else is wrong.

6.)  Re-seating... Pull the interface card out of the slot it is currently
in and put it back in the same slot.  Or, pull the card out of its 
current slot, and put it back into a different slot.

7.)  Reduce your CONFIG.SYS and AUTOEXEC.BAT  files to the bare 
minimums.  You will only want to load CD-ROM driver in the 
CONFIG.SYS.  In the AUTOEXEC.BAT file, you 
will only want to load MSCDEX.EXE.

8.)  Change EMM386 to the version that came with Windows 3.1.  Here is
a sample line:

DEVICE=C:\WINDOWS\EMM386.EXE RAM 1024

If these suggestions do not work, the drive needs to be serviced.

49. 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 the
Pro Sonic 16. Inform TTS that you are looking for a Sound Blaster Pro 
CD audio cable for a NEC, Mitsumi, Sony, Texel or Toshiba, etc., etc..
Here are the telephone and fax numbers for TTS.

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

50. What are the Audio cable pin-outs on the Pro Sonic 16?
Here are the pin-outs for the audio connector on the Pro Sonic 16

PIN - 1 = NC
PIN - 2 = LEFT
PIN - 3 = GROUND
PIN - 4 = RIGHT

51. 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: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.

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

52. I am unable to use the Media Player in Windows to play 
audio CD's.  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

53. 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.  Before we automatically assume that the driver needs
to be replaced, try adjusting the BALANCE on the Pocket Mixer.

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 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.

54. 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.

55. 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.

56. 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=VPASD.386
DEVICE=VSBD.386
DEVICE=VSBPD.386
DEVICE=VSGLX16.386
DEVICE=VSGLD.386
DEVICE=VSGD.386
DEVICE=VSGLX.386

57. My DOS applications will not work properly when run 
through Windows.
Try remarking out the following drivers in the SYSTEM.INI with semi-colons.

;;DEVICE=VPROSD.386
;;DEVICE=VPROSFM.386

You should find these drivers in the [386 Enh] section.

58. 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.

59. 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

DEVICE=C:\PROSONIC\PROS.SYS  A220  D1  I7  E5  T330  Q2  V


AUTOEXEC.BAT

SET BLASTER=A220 I7 D1 H5 T4

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 (PROSONIC).  Test the sound by 
entering the following line:

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

You should hear the .WAV file play once.

If this does not sound normal, adjust the IRQ setting on the 
PROS.SYS line in your CONFIG.SYS file.  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 [pros.drv] section near
 the bottom of the SYSTEM.INI file.

60. 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.

61. 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:\PROSONIC\PROS.SYS  A220  D1  I7  E5  T330  Q2  V

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 (PROSONIC).  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.

PLAYFILE  TEST.WAV	[enter]

You should hear the .WAV file play once.  If you hear no sound,
adjust the thumbwheel on the back of the sound card.

Try the PLAYFILE command again

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 I  parameters on the PROS.SYS 
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=vprosd.386
device=vprosfm.386
dmabuffersize=064

[drivers]
mixer=prosmxd.drv
wave=pros.drv
midi=prosfm4.drv
midi1=pros401.drv

[pros.drv]
port=220
int=5
dmachannel=5

[pros401.drv]
port=330
int=2

[prosfm]
drumchannel=10

62. 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.

63. I am getting the following error message, "Illegal DMA 
Channel Specified."
Make sure the PROS.SYS driver is loaded after HIMEM.SYS and 
EMM386.EXE.  Also try adding the V switch on the end of the 
PROS.SYS line.  Here is a sample line:

DEVICE=C:\PROSONIC\PROS.SYS  A220 D1  I7  E5  T330 Q2 V

If adding the V switch to the PROS.SYS line does not solve the
problem, please download PROS.SYS from the Media Vision BBS.
The updated driver should be the solution to the problem.  The number
for the BBS is  (510)  770 - 0527.

64. I know that the Pro Sonic 16 uses a thumbwheel to control 
volume, is there a way to control the volume via my 
keyboard?
Yes, you can use CTRL + ALT + U to increase the volume.  
You can use CTRL + ALT + D to decrease the volume.  
You can also use CTRL + ALT + M to mute and unmute the volume.
Please note that these controls will only work under Windows.

65. When PROS.SYS loads, I get one of the following error 
messages," Invalid DMA Channel Selected" or "Unknown 
Jazz Family Found."
Move  PROS.SYS above DoubleSpace in CONFIG.SYS.  Load PROS.SYS
from the uncompressed partition on your hard drive.  Ensure that you are only
loading one copy of PROS.SYS in the CONFIG.SYS file.

66. I am getting the following error message, "Cannot acquire 
int 2F interface failing load."

This error will occur if a previous PROS.SYS device driver has been loaded.
Look for another PROS.SYS line in CONFIG.SYS

67. I am getting the following error message, "No interrupts, 
stopping playback," when using PLAYFILE.
The Pro Sonic 16 PROS.SYS driver is loaded more than one time
in the CONFIG.SYS.  Verify that the CONFIG.SYS has only one 
DEVICE or DEVICEHIGH statement for the PROS.SYS driver.

You will also get this error in PLAYFILE if the SET BLASTER line 
in AUTOEXEC.BAT does not reflect the same settings as on the 
PROS.SYS line which you will find in your CONFIG.SYS file.

68. Some of my sounds under Windows play fast.  It sounds 
like my card is one of the Chipmunks.  How do I fix this?
You can fix this by adding the following line to the [PROS.DRV]
driver settings in the SYSTEM.INI file.

Samplemode=Soundblaster

Here is a sample section:

[PROS.DRV]
PORT=220
INT=5
DMACHANNEL=5
Samplemode=Soundblaster
