I'm guessing that it has to be a setting in mythtv somewhere because I get
sound through the TV from other sites and from VLC media player. The
commands from this link "http://ubuntuforums.org/showthread.php?t=2001545"
returned command not found (approximately) and from the "aplay -L" command
I can see it is card=generic device=3, but I need help from here.
Suggestions greatly apreciated.

Daryl
