2 sound cards
 

I have mandrake on my pc, but i have 2 sound cards, i want to kown how to disable one of them.

look in /etc/modules.conf

You'll see entries for both cards.

Change any entries so that the FIRST device has the lower number...

e.g. swap 2 for 1 where needed.

alias sound-slot-1 snd-emu10k1
alias sound-slot-2 snd-intel8x0

Makes the Soundblaster Live the FIRST card in the system which is used by default..
Originally these were swapped.

Finally to completely disable the second card (which is not really needed once you've done the above...) add "OFF" as the second entry.

Let's say your machine has an imbedded INTEL 8x0 sound card...

change the line to read

alias snd-intel8x0 off

is one of them built onto the board? If so i would just disable it in the bios.

Quite often, even if the on board audio is disabled, it is detected and re-enabled by Linux.

hmmm, that has never EVER happened to me, but i guess its not impossible.

Yeah I've had it happen far too often, even in Winblows.

It seems to be hit and miss, on some MB's disabling the device works great.

On others using different chipsets, it's a crap shoot.
