Slack 12.1

Hi,
How do I disable the motherboard sound and use a pci card only?
I got the pci card working using alsaconf but KDE just wont use it.

When I run 'alsamixer" I get:
alsamixer: function snd_ctl_open failed for default: No such device

It works with my TV card and Amarok. But no system sounds.

Solved:
I rebooted and everything started working.

You might find an option in the BIOS to disable the on board sound-chip and it is probably worth doing this if you do not want to use it. That is what I have done on my system.

I have the onboard soundchip disabled in the BIOS of this Asus K8V-X board.

Code:

anna@peter:~$ /sbin/lspci | grep -i multimedia

Until Slackware-12.1, it's modules did not load. However, it now loads. To
keep the modules from loading I added it to "/etc/modprobe.d/blacklist":

Code:

blacklist snd-via82xx

So now it does not load:

Code:

anna@peter:~$ lsmod | grep -i snd

However, even with it loaded, the sound worked fine. Check your volumes
in alsamixer for both sound chips. Muting the onboard should work, also.

Thanks!
After I "thought" I had if fixed the problem came back after another re-boot.

So, as you both suggested, I got in to bios an disabled the on board sound and now everything is once again perfect in happy land.
