How to disable onboard audio card?

Hi!

Have one audio PCI card and VIA82xx audio chip onboard.. problem is that ALSA loads drivers for both cards and seems that I can't use only PCI one.. for example, I can't get Xine play audio through PCI, it insists on playing through onboard card.. while XMMS plays through PCI one.. I want use just PCI card because it is better.

I disabled onboard card in BIOS, but ALSA still loads it and it works like not disabled..

Hot to tell ALSA not to load it?

Thx

hi

have you emerged alsa-drivers?

have the pci card and the onboard the same driver?

if the drivers are not the same you can only activate the drivers in your kernel, for the card that you want to use.

If you disabled it correctly in your bios, gentoo shouldn't even see the card. It would seem as it's not even there. You should be looking in bios settings or a bios upgrade, not alsa.

I agree.
By disabling it in BIOS it effectively does not exist.. So no operating system should see it.
Check your bios again.

If youre using alsa-drivers, just set ALSA_CARDS="whatever" in make.conf and reemerge it. See the ebuild for details.

If you don't build the drivers for the card it won't load them.

Otherwise in /etc/modules.d/alsa set the cards
alias snd-card-0 snd-? # for the pci card, will be default
alias snd-card-1 snd-? # for the via card

if you built the modules in this may not work and you have to figure out some other way.
