I don't have a very detailed answer but here goes. First make sure that the
coax port is an input (just because you card lists an input doesn't mean it
has it) and second I believe that in mythtv-setup you can select an audio
device for caputre. I'm one of those "lucky" guys so sorry I couldn't be of
more help.
