Sound Problems with Yamaha OPL3

Poor Sound Quality

If the PC shows problems with poor sound quality when running Multimedia CDs, try this -

• Go to Start / Settings / Control Panel.
• Double click on the OPL 3-SAX Config icon.
• Change the quality setting from Excellent to Good.
• Click on the OK button.

If the problem still persists after that, you will need to reinstall the drivers, which can be done by,

• Place the Yamaha CD in the CD-ROM drive.
• Double Click on the My Computer icon.
• Double Click on the (D:) icon.
• Double Click on the Setup folder.
• Double Click on the Setup program.
• Click on Next, and choose Typical Configuration. Agree to any other questions.

Yamaha SoundCards in DOS

To get sound to work in Dos after a reboot you must go into the SETUP directory on the Yamaha sound drivers CD and run Setup, which will add the relevant lines into your autoexec and dosstart files.

No Sound

If you get no sound at all, and you've checked the obvious (ie speakers turned off, Windows volume turned down low). You may need to remove and reinstall the soundcard.

• Click on Start / Settings / Control Panel / System / Device Manager.
• Remove any references to the OPL3 soundcard. Normally in 'Sound, Video & Games Controllers', and 'Other Devices'.
• Shutdown and Restart the Computer.
• It should re-detect the Soundcard.
• If it asks you for the location of the drivers, insert the Yamaha CD and tell it to look in the D:\WIN95 directory.
• When the computer gets back into Windows, run the Soundcard Setup program from the Yamaha CD. Click on Start, Run, and run the program D:\SETUP\SETUP.EXE
• Choose 'Typical Configuration' and agree to everything else.
• Job done.

FDD Failure

Upon starting the machine, you may get the above message. Solution is to go into the BIOS (Press the DEL key when the machine is starting up), and in the I/O Configuration Setup, set the Floppy Disk Drive Controller to Enabled.

Reinstallation Problems

If you get an error message reinstalling a CTX machine, something like SU99S038, check the autoexec.bat file on the floppy disk. On the oemsetup line, check to see if there is a /K switch. This switch is invalid, and won't work. To cure the problem, delete everything after oemsetup on that line and it should then reinstall properly.
