I had a similar problem with my MythTV setup on Ubuntu.  The issue
with ALSA was the TV tuner card's sound output adding itself to the
list of audio devices.  I have a pcHDTV card.

This is what I did to get around it (.bash_profile):
asoundconf reset-default-card
cardNum=`asoundconf list |tail -n2 | grep -n NVidia | sed -e 's/:.*//'`
cardNum=$(( $cardNum - 1 ))
asoundconf set-default-card $cardNum

amul@mansion:~$ asoundconf list
Names of available sound cards:

That CX8801 is my pcHDTV 5500 (I used to have two, but one died).
