You should have immediately returned the card if HDMI did not fit.

What does the speaker test produce in alsa and/or gnome/kde, etc..  I
believe long ago, Jean Yvess (sp?) killed pulse when mythfrontend started
playback, but I do not know if that is still the case.  You definitely do
not want anything except alsa for digital audio.

Also, when selecting the different modes from the TV GUI, I always had to
restart mythfrontend (that was long ago though - YMMV).
