The sound card detection program does see it but no sound come out when I
test it. I'm not sure but I think that the nvidia chip set may be quite a
new one and I'm beginning to think it might not be supported yet in
Linux.
The listing for a driver implies that it is supported. This might be a
dumb question, but did you check the volume settings in the mixer app?
Not such a dumb question, I had tried running the alsamixer command when I had
F7 installed but not after getting rid of F7 and installing CentOS. I have
just tried the command from the cli and here is what I got.
[john@localhost ~]$ alsamixer
alsamixer: function snd_ctl_open failed for default: No such device
[john@localhost ~]$
When KDE starts up it gives me a error message about the sound problem. Next
time I reboot I will make a note of what it is. I know that the speakers are
plugged into the correct socket as this machine is one of two that dual boots
windozs and I get sound when I run windoz to play games.
I'm off to bed now as its just past 5am so will shut down this box and have
another try later on today. Thanks for the help so far though.
That means the driver isn't loaded. 'modprobe snd-mpu401' as root and
try again.
I have a similar board from Asrock which has apparently the same onboard audio
card; on my FC5 install the audio module used is snd-hda-intel and the sound
works... the relevant section in /etc/modules.conf is:
alias snd-card-0 snd-hda-intel
options snd-card-0 index=0
options snd-hda-intel index=0
remove snd-hda-intel { /usr/sbin/alsactl store 0 >/dev/null 2>&1 || : ; };
/sbin/modprobe -r --ignore-remove snd-hda-intel
