I had a similar problem on a zd7000, and I had to add
to /etc/hotplug/blacklist

To find that out, do a
# lsmod | grep snd

If you find something like (I think it was that line):
snd_ac97_codec         88893  1 snd_intel8x0,snd_intel8x0m

then blacklisting snd_intel8x0m like I said above might be the solution.
