This document details the most common questions and answers regarding Logitech Sound Boards under. This is written with the assumption there is a general understanding of working with files and directories under DOS and Windows 3.1x or Windows 95 in order to accomplish the instructions detailed in this document.
If you do not see your situation described in this document, please check our Customer Support Document Catalog to see if we have another document which might help you.

Q: How do I set up the SoundMan Wave to work under Windows 95?

A: For Windows 95 users, please download WAVE95.EXE, this is the updated SoundMan Wave driver. This is a self-extracting file. Follow the installation instructions in the READ1ST.TXT file. Windows 95 installation and configuration questions for SoundMan Wave are addressed in Customer Support Document #3340, "SoundMan Wave Version 1.0 driver under Windows 95".

Q: When I start the installation for the SoundMan Wave, the system locks up with a blue or black screen.

A: If the system uses a PCI bus, then it is possible the PCI bus default configuration is using IRQ 9 (also referred to as IRQ2/9 Cascade IRQ). The SoundMan Wave board is trying to access IRQ 9 during the installation. To correct this, please do the following:

1. Enter the CMOS setup.
2. Enter Advanced CMOS setup.
3. Enter the section which allows you to specify the IRQ settings and whether they are available for use by PCI/ISA cards or ISA only devices. These sections have been labeled on some computers as Integrated Peripherals but have also been seen in the Plug and Play section.
4. Change IRQ 9 to "ISA Only" and change IRQ 10 to "PCI/ISA". PCI/ISA means PCI and ISA cards can use this IRQ setting. The descriptions used to identify ISA Only vs PCI/ISA may vary depending on the manufacturer of BIOS and revisions. Please refer to the system documentation or use the help screen in the CMOS setup to identify. On some computers we have seen that changes must be made to IRQ 10 before you can alter IRQ 9 settings.

Q: During the installation, the test for the General MIDI port appears to fail. Why?

A: One possible cause is the installation of NDOS or 4DOS. Another reason is the system has a peripheral device (i.e. SCSI controller, scanner card) which by default uses Port Address 330h. Change the General MIDI port address to 310h or 320h. If the test still fails, please refer to the documentation for the peripherals in order to determine if the device can be set to use Port 340h or another Address outside of the Address range used by the SoundMan Wave. For example, if you have an Adaptec 1542C or 1542CF, change the port Address to 134h to avoid any conflict with the SoundMan Wave Port Address scheme.

Q: How do I set the Sound Blaster to use IRQ 10 or 15?

A: To configure the Sound Blaster half of the SoundMan Wave to use IRQ 10 or 15, edit the SOUNDMAN.INI file:

1. Open the SOUNDMAN.INI file in a text editor such as Windows Notepad.
2. Change the number on IRQ= line in the [WAVE] section to 10 or 15. Save the changes.
3. Open the AUTOEXEC.BAT file.
4. On the SET BLASTER line change the "I=" setting to I=10 or I=15, depending on which IRQ setting you will be choosing.
5. Save the changes and restart the computer.

NOTE: Changing the Sound Blaster IRQ to 10 or 15 may result in the Sound card not being recognized in some DOS-based program. The reason is that Sound Blaster cards are rarely set to use IRQ 10 and 15 and many software developers do not support these settings on. Sound Blaster compatible sound boards. If you are only going to work with a Windows based program, selecting IRQ 10 or 15 will not be a problem.

Q: Why do I get repeating sounds during hardware test?

A: The most common cause is an interrupt conflict. Identify which part of the test fails, Sound Blaster or General MIDI (MPU 401). Change the appropriate IRQ setting by running the SETUP program for SoundMan (Sound Blaster and General MIDI interrupts MUST be set to different values). To maintain Sound Blaster compatibility with your DOS based games, use IRQ 5 or 7. If you have to use another IRQ, then some DOS-based games may not recognize the sound board. Also, check for COMMAND.COM replacements such as NDOS or 4DOS. Restart the computer with a bootable DOS diskette to avoid such conflicts. While repeating sound is typically an IRQ conflict, DMA channel conflicts can present the same symptom. Once the possibility an IRQ conflict has been eliminated, try changing the DMA for 16-bit audio from DMA 5 to DMA 3 or 7.

Q: My Adaptec SCSI controllers and the SoundMan Wave are conflicting with each other. How do I correct this?

A: Adaptec SCSI controllers will often use DMA 5 by default. This setting is the same as the 16-bit DMA on the SoundMan Wave. Choose another 16-bit DMA setting such as 3 or 7. If you have the Adaptec 154x board which uses DMA 5 and Address 330h by default, then this will conflict with two of the SoundMan Wave default settings (DMA 5 is used by the 16-bit DMA Channel and Address 330h is used by the General MIDI (MPU 401) interface). To resolve the DMA conflict, choose another 16-bit DMA for SoundMan such as 3 or 7. For the General MIDI (MPU-401 Emulation) part of the board, you have 2 options: change the I/O Address of the MPU 401 port or change the board base address of the SCSI controller.

1. If you change the MPU 401 I/O Address, some older DOS-based programs will only detect MPU-401 interface to be at Address 330. Therefore, these programs will no longer work. Many new programs will support non-standard Address settings when choosing General MIDI.
2. Changing the I/O Address on the Adaptec 154x controllers is another option. Some boards may require an updated ROM to support alternative Addresses. Only the 1542C and 1542CF have a ROM which supports alternative address settings and this will also require jumper changes on the Adaptec board. Refer to your Adaptec documentation for information on how to alter boards settings.

Q: I get distorted sound, no digital audio, Parity errors, or my game locks up. Why?

A: All these symptoms can be attributed to a DMA conflict. SoundMan Wave uses DMA 1 for Sound Blaster compatibility and DMA 5 for recording and playback 16-bit sound files.

Q: I get a "Memory Parity Error" after installing the SoundMan Wave. Why?

A: A DMA conflict, or BUS clock speed not set to 8 MHz will result in incorrect system timing. The system timing can be affected by the Bus speed, Cache and Shadow ROM. Sometimes the system speed can cause these symptoms. To adjust the bus speed, go into the CMOS Setup for the computer. Look for any line which refers to Bus Clock or Timing. The figure will most likely be expressed with the letters CLK. For example: Bus Speed CLK/4. To figure out the Bus Speed, divide the number by your system's clock speed. For example, a 486/33 with a bus speed of CLK/4 would be running at a bus speed of 33/4 -- or roughly 8 MHz. If it was set to CLK/3, that would be 33/3 -- or roughly 11 MHz. Industry standard bus speed is 8 MHz. Make sure the bus speed is not set too slow or too fast. If you are familiar with CMOS Setup, try various bus speed settings. Start with the CLK/ at the lowest setting and test the sound card's performance at each bus speed. If you are not familiar with the procedure for adjusting bus speed, consult the documentation for the system or contact the system manufacturer. If adjusting the bus speed does not correct the symptoms, try disabling External or Internal Cache. If the symptoms are not corrected, then please refer to Customer Support Document #3220, "Standard Diagnostics for Logitech Sound Boards Under Windows 3.1x / DOS".

Q: I connected a joystick to my SoundMan Wave and it does not work. Why?

A: First, make sure you do not have a second joystick port on the system. Only 1 port can be active in a system at one time. Second, verify the jumper on the SoundMan Wave is offset (covering only 1 pin). If a joystick port exists on the system in addition to the port on the sound board, connect the joystick to the system's joystick port and disable the joystick port on the SoundMan Wave by setting the jumper on the board to cover both pins. Make sure the SoundMan Wave device driver (SMWSET.SYS) is loaded in the CONFIG.SYS file. If the driver is not loaded in the CONFIG.SYS, then other programs may not recognize the jumper setting for enabling or disabling the Joystick port.

NOTE: Disabling the joystick port on the sound card will not disable the function of an external MIDI adapter. However, some faster computers may experience symptoms with the joystick port. If this occurs, you may need to get a joystick interface card which is speed adjustable.

Q: Digital Audio (Voice/Special FX) is coming out of 1 speaker only in game. Why?

A: This occurs when the game has been set up to Sound Blaster Pro. The SoundMan Wave is not Sound Blaster compatible but NOT Sound Blaster Pro compatible. After changing the set up back to Sound Blaster, you must restart the computer in order to reset the hardware.

Q: After installing the SoundMan Wave, there is no sound (i.e. WAV or MIDI ) in Windows 3.1x. Why?

A: Make sure the Mixer settings in MCS Music Rack for SYNTH, WAVE and MASTER are turned up. Verify the Windows drivers have been installed. This can be done by going to Control Panel, then Drivers. If not, reinstall the SoundMan software. The drivers which should be listed include:

SoundMan Wave Audio
SoundMan Wave Mixer
SoundMan MIDI
Timer
Midi Mapper
[MCI] MIDI Sequencer
[MCI] Mixer Control
[MCI] Sound

Other drivers may appear but make sure these are listed. If drivers for another sound card are listed, remove them.

Q: After recording at 44 KHz or 16-bit, there is noise or distortion on the files. Why?

A: The SoundMan Wave may not record or play at 44 KHz sampling rate or at 16-bit. Try recording at a lower sampling rate. This is usually a result of slow CPU speed. Limited memory or slow hard drives can also cause this to occur.

Q: Can I run a DOS based (w/ Sound Support) application in a Windows DOS box?

A: Due to the complexity of games and SoundMan Wave drivers, attempts to run a DOS based application from Windows may cause a system crash (it may even damage the file system on the hard drive). If you wish to use DOS based applications which support sound, it is recommended to exit Windows and run these applications from DOS.

Q: Where do I get a MIDI adapter to use with my Logitech sound board?

A: In the U. S. and Canada, please call AMC at 1-800-882-0587. They are selling the MIDI adapter box, cable, and manual for $44.99. AMC will be providing technical support on their products.

Q: Where can I purchase a CD-Audio cable to connect my internal CD-ROM drive to my SoundMan board?

A: In the U.S. and Canada you can call Pacific InterConnection at 800-706-0510 (Mon-Fri 7:30-5:30 PST). Pacific InterConnection will need to know which sound board you have and the Make/Model of the CD ROM.

Q: When attempting to play a MIDI file, I get the error message "File may not play correctly with default MIDI setup". Why?

A: The file may be missing the header information which indicates it is a General MIDI file. Enable the "Don't display this warning in future" selection. Most MIDI files today are created as General MIDI. After making this change, the file should begin to play. If the file is not true General MIDI, then different instrument sounds may be used.

Q: What CD-ROM drives are supported on the SoundMan Wave SCSI interface?

A: The SoundMan Wave SCSI driver (Z5380.SYS) should work properly with most SCSI single disk CD-ROM drives. The only exceptions are multi CD changers such as Sony's 55S and 76S drives. On these drives, only the firs t disk will be recognized. The Sony drives will work properly with CD ROM disks, but Audio CD's cannot be played. The following steps will allow you to modify the SCSI driver to work with the Sony 55S ONLY. No solution is available for the Sony 76S. Follow the steps that correspond to the driver version being used with SoundMan.

1. Use DEBUG to patch the existing driver. First, make a backup copy of Z5380.SYS called Z5380.OLD.

2. Then, edit the Z5380.SYS as follows:

Version 3.04	Version 3.15
DEBUG Z5380.SYS	DEBUG Z5380.SYS
E 7B2B	E 7EAE
20	20
W	W
Q	Q

3. Reboot the computer and test.


Q: Is the SCSI CD-ROM controller on the SoundMan Wave board 8-bit or 16-bit?

A: The controller is 8-bit. The SoundMan Wave is fully capable of maintaining the throughput necessary for single, double, triple, and quad-speed CD-ROM drives.

Q: Does the SoundMan Wave SCSI CD-ROM interface support anything in addition to CD-ROMs (i.e. Hard Drives, Tape Backups, etc.)?

A: No.

Q: Where can I get the SCSI driver to use my SCSI CD-ROM on the SoundMan Wave SCSI CD-ROM interface?

A: Refer to Section 3.3 of the SoundMan Wave README.TXT file for instructions on setting up your CD-ROM drive manually. The following items are required:

1. The CD-ROM Extension Driver, MSCDEX.EXE. If you have DOS 6.x, this file is located in the DOS directory.
2. A 50-pin SCSI cable.
3. A CD-Audio cable. The pinouts for this connection are found on page 69 of the SoundMan Wave User's Guide. In the U.S. and Canada, you can contact Pacific InterConnection at (800) 706-0510, Monday through Friday between 7:00-6:00 PST to purchase these items. Or, you may be able to locate this cable at the local computer store.

Q: I have a non-SCSI CD-ROM drive (e.g. Mitsumi, Panasonic, Sony, Reveal), can I use it on the SoundMan Wave CD-ROM Interface?

A: Yes. However, you will not be able to use the SCSI CD-ROM connection on the SoundMan Wave. You will need a proprietary controller board for the particular CD-ROM drive model. You can use the CD-Audio connection (the 5-pin connection on the board) found on the SoundMan Wave to allow audio CDs (i.e. music CDs) to play. The pinouts for this connection are found on page 69 of the SoundMan Wave User's Guide.

Q: Why is my CD ROM running slowly?

A: Remove the /M1 switch from the Z5380.SYS line in the CONFIG.SYS file.

NOTE: Some CD-ROM drives require this switch to be present for normal performance. If removing the /M1 switch generates CD ROM read error, restore the /M1 switch. The /M1 switch which appears on the Z5380.SYS line in the CONFIG.SYS file has no relation to the /M:10 switch on the MSCDEX.EXE line in the AUTOEXEC.BAT file.

Q: My game says I need a later version of the Trantor SCSI CD-ROM driver for the game to work correctly. Why?

A: The SoundMan Wave is currently shipping with v3.04a of the Trantor driver. If you have modem, please download the updated driver v3.15, CDRUPG.EXE.

The file is self-extracting and contains the updated version of the file Z5380.SYS. An example of this would be
the game Megarace from Software Toolworks.

Q: Can I use Corel SCSI or Adaptec's EZ SCSI drivers with the SoundMan Wave SCSI interface?

A: No.

Q: Is the SoundMan Wave compatible with the Media Vision Pro Audio Spectrum 16 or Pro Audio Studio board?

A: No. SoundMan Wave is Sound Blaster and General MIDI compatible.

Q: Will the SoundMan Wave work in Windows NT or IBM OS/2?
A: There are no drivers available for this device under Windows NT
