I have a I/O ver 4b. Win98se sees the audio as 2 separate devices 1-VIA AC'97 WDM controllr and 2-Yamaha OPL3-SAx Sound System. Problm is with the Yamaha OPL3. Driver install always aborts with an error leaving the Yamaha device with a yellow exclamation mark. Thing is I had sound before I installing the Yamaha driver.
The Yamaha drivers (from various links off this board) do not work with a RISE chip. They work with pentium and AMD chips only. You need to remove all traces of the yamaha sound stuff both from device manager and the control panel. Reboot and let Windows use it's default drivers. Sometimes it is necesary to reinstall windows to get your sound back. Or you could upgrade to a Pentium 200.....an easy drop-in upgrade.
I re-installed W98se and got the audio to work. Device manager shows a Yamaha OPL3-SAx and an unsupported multimedia device with an exclamation mark. I re-installed the VIA audio driver and got back to normal. Not out of the woods yet as the parallel port ethernet driver is being a b*itch.
It seems the Yamaha drivers are the source of the problem. It can't easily be undone once the Yamaha drivers are installed. I re-gedited all references to OPL3 and Yamaha out of the registry removing all parent keys and still so avail.
