Hi Thomas. I can see a couple of ways around your problem from the above
output you have provided.
1st. If you are not bothered about the onboard soundcard being used, you can
add a line to /etc/modprobe.d/sound as below.
install snd_via82xx /bin/true
This will send the module to true, and it will be ignored. As you already have
alias, and options lines in /etc/modprobe.d/sound for snd-emu10k1, a reboot,
a doing a cat /proc/asound/cards (hopefully) will now show the audigy card as
card0.
I've had a lot of these sorts of problems, particularly with my usb midi
keyboard which uses snd-usb-audio. USB starts early in the boot process, and
usually I find that before setting options lines, the midi keyboard (which
isn't a soundcard) is being set as card0. Similar problems with snd-bt8xx. A
notorious module, and known to grab card0, which is often why you find
default options lines setting it as card2 (my TV card uses this for capturing
sound)
2nd workaround.
From your cat /proc/asound/cards, the snd_via82xx module is recognised as
card0, but your /etc/modules.d/sound also has snd-emu10k1 as card0, as below.
Dragon:~# cat /proc/asound/cards
0 [V8235 ]: VIA8233 - VIA 8235
VIA 8235 with ALC650E at 0xec00, irq 11
Dragon:~# cat /etc/modprobe.d/sound
alias snd-card-0 snd-emu10k1
options snd-emu10k1 index=0
So as root in a text editor make a couple of changes in /etc/modprobe.d/sound,
as below.
Add the following line:
options snd_via82xx index=1
Change the alias line for snd-emu10k1, so that it reads:
alias snd-card-1 snd-emu10k1
I'm not booted into Debian at the mo, and have forgotten the incantation to
stop and start alsa, but a reboot will see if this works.
All the best.
Nigel.
btw Florian, apologies for poking my nose in on this thread.
