nForce sound locking up system

[shroom]

I have an MSI Nforce 420 motherboard, and RedHat 7.3 with a default workstation install.

Everything is installed and working alright, but the soundcard (builtin) is having major issues. When anything tries to use the card it frezzes up in this manner: (specifc example from sndconfig 's testsound atempt)

I tried sndconfig, choosing the ac97 i810 driver (that it auto-suggested). It hang with this:
i810_audio: Audio Controller supports 6 channels
i810_audio: AC'97 Codedec 0 unable to map surround DAC's (or DAC's not present), total channels = 2
AC97_codec: Secondary AC97 codec not present
i810_audio: timed out waiting for codec 1 analog ready

lsmod lists nothing for sound

I have gathered that the i810 linux sound driver is unable to process the 5.1 channel (technically 6) souround sound.

Does anyone know how to get sound working correctly on RedHat 7.3? The nvidia sound drivers were troublesome for me, but if they can be made to work I suppose.

I am having the same problem on the same board...did anybody every find a resolution to this? Please help!

hi,

check out http://www.nforcershq.com/forum/viewforum.php?f=29 for a detailed installation guide that might help.

Ok. I followed the guide, deviating in a couple places:

First of all the suggested alias:
alias eth0 mcpeth
is nuts. nvnet works just fine for me. Different board maker or something? anyhow, not a problem

Second, the sound. There we have wierdness. The i810_audio driver is supposed to work on its own? Does the nvidia sound driver replace it in some way? My /etc/modules.conf is like this:
[Colin@localhost Colin]$ cat /etc/modules.conf
alias parport_lowlevel parport_pc
alias sound-slot-1 i810_audio
post-install sound-slot-1 /bin/aumix-minimal -f /etc/.aumixrc -L >/dev/null 2>&1 || :
pre-remove sound-slot-1 /bin/aumix-minimal -f /etc/.aumixrc -S >/dev/null 2>&1 || :
alias usb-controller usb-ohci
alias eth0 nvnet
alias char-major-195 NVdriver

I have commented out the two wierd sound lines to no avail. I later added the char-major-195 line, which gave me a microphone loopback, and a hiss suggesting the headphones were on, but no sound.

Any thoughts? I will be troubleshooting this with the local linux guys (irc.openprojects.net 6667 #orlug) and I will report back if I find something.

Edit some futher info from dmsg:

Is it using the nforce ones anyway? Can they be
'nutered' to use the 810's without affecting the lan drivers?

A little more information:

[root@localhost root]# modprobe i810_audio
/lib/modules/2.4.18-3/kernel/drivers/sound/i810_audio.o: init_module: No such device
Hint: insmod errors can be caused by incorrect module parameters, including invalid IO or IRQ parameters
/lib/modules/2.4.18-3/kernel/drivers/sound/i810_audio.o: insmod /lib/modules/2.4.18-3/kernel/drivers/sound/i810_audio.o failed
/lib/modules/2.4.18-3/kernel/drivers/sound/i810_audio.o: insmod i810_audio failed

I know little of the linux driver system, but I suppect that if the above ran correctly I would have sound. What needs to be done to make it work?
