Choosing which soundcard to use at startup?

[Michael Hirsch]

I have two soundcards in my system, and AMD soundcard that is built
into the motherboard, and a Creative Audigy card:
sudo lspci | grep audio
0000:00:07.5 Multimedia audio controller: Advanced Micro Devices [AMD]
AMD-8111 AC97 Audio (rev 03)
0000:03:0a.0 Multimedia audio controller: Creative Labs SB Audigy LS

I use artsd and it all works pretty well, but there is one problem.
Every once in a while the device changes.  When that happens I get no
sound from my speakers.  I end up fiddling with the controls for a
while, then I just switch the jack at the back of my box from one plug
to the other and it works again.

How can I make artsd always use the audigy card?  I can't find
anything that configures this.  I wouldn't mind being able to
completely disable the AMD card, too.  Currently, both sound modules
load which seems a waste.

Thanks,

Michael
