hello! I'm finishing up installing Alsa drivers on my Red Hat 9 partition. RH 9 recognized my VIA82C sound card. But I decided to switch to Alsa drivers. I downloaded last release (9.5). After installing alsa drivers there was a noise after a sound was played. On the sound server setup I selected: Use custom sampling rate: 48000 and: Other custom options: -a oss After compiling the drivers, be sure to run snddevices. If you miss it, then amixer and alsamixer will not run. Then, I compiled and installed the alsa-libs and then alsa-utils. I run alsamixer several times to change PCM and Master controls to different levels to test aplay /usr/share/sound/startup3.wav. Aplay played sounds at volumn levels controlled by alsamixer. So, I think you missed to run snddevices under the alsa-drivers directory. I hope this will help you. The same Alsa drivers are running very well on my RHat 8.0 partition.
