I cannot get the Yamaha OPL3-SAx sound system to work on a Toshiba Tecra 8000 notebook computer. I installed the sound drivers, but I get no sound from either the notebook speakers or from external speakers plugged into the sound port on the back of the notebook computer.
I loaded Windows 98 on a Toshiba Tecra 8000 notebook computer and downloaded the Windows 98 drivers for the Yamaha OPL3-SAx sound system from this site:
The sound drivers installed, but then I got a "PCI Multimedia Device" in the Windows 98 Control Panel / System / Device Manager / Unknown Device section. I followed the instructions on the Toshiba FAQ at this (very long) site:
The instructions were:
When reinstalling Windows 95 on certain machines (including Tecra 8000, Portege 7000 series), there may be a conflicting device shown under Windows 95 System Properties / Device Manager / Unknown Device section. The conflicting device is usually identified as "PCI multimedia audio device" or "PCI multimedia device".
To fix this problem, modify the registry as follows:
Click "Start," then click "Run." Enter "REGEDIT.EXE" and hit the "Enter" key.
From Registry Editor menu, click "Edit" and select "Find". Place a Check for "MATCH WHOLE STRING ONLY". Enter either "PCI Multimedia audio device" or "PCI Multimedia device" (whichever is shown under Device Manager/Unknown device section). Click "Find Next" to search for this device in the registry.
Change registry key CLASS from "unknown" to "Sound, video and game controllers". Change the registry key "ConfigFlags" from "40 00 00 00" to "00 00 00 00".
Restart Windows 95 to allow the change to take effect.
When I did this, the PCI Multimedia Device went away from the Unknown Device section, but the sound system still does not work at all.
I do get a speaker icon on the lower right corner of Windows 98 and I do have the Yamaha OPL3-SAx Sound System showing as working properly under Control Panel/Device Manager/Sound, Video, and Game Controllers. I also have an icon for OPL3-SAx Config in the Control Panel.
I would greatly appreciate it if anyone can fix this problem. I've assigned 500 points to give for your trouble.
