I used the alsa driver for the my sound card and the soundcard detection has found it as

Vendor: Intel Corp.
Model: 82801EB AC'97 audio
Module: snd-intel8x0

but when i open the volume mixer it says unable to open audio device 'dev/mixer'

Also when i shut down redhat9 there is one failed
modprobe: can't locate module sound-service-0-0 aumix: error opening mixer.

I am pretty much a newbie and having been trying to get this to work for a week now . PLease help.
