I have not seen a card show up as "front" before like that, but I
assume it is default..  Never used USB sound, but know it will work
since you can hear from it.  Just need to nail down exactly what alsa
calls it and setup the pcm device I guess (like in the post)..  Make
sure the user that mythtv runs as is the directory it goes in.  And
you will need to restart mythfrontend for sure (maybe log out and back
in as the user as well.  I cannot remember exactly when creating
those.

OK, you're setup properly there then.  Can you make sure the video you
are trying to play in myth is stereo only as well.
