"Cannot open" usually means that the user doesn't have
permissions to read or write to the file...

The first few characters say that only the owner "root"
can read and write. As root, try "chmod 666 /dev/audio".
then ls -l should show the permissions "crw-rw-rw-". Run
xawtv again as a regular user. If you still don't get sound,
use a mixer program to unmute and set the volume for "line"
assuming you plugged the external mini-jack into line-in.
Once you get sound from xawtv, use the mixer to leave the
volume where you like and mute "line" then try mythfrontend.

Hope this helps,
