[clug] MythTV backend uncommunicative

[Stephen Gibson]

Note, nothing clever on my part, I am pretty sure that the audio was 
automagically detected with the mythtv wizard.

Mythfrontend audio:

ALSA:hw:CARD=PCH,DEV=7

no digital component items

Speaker config: Stereo

HDMI connected to TV.

This system is ASRock H61M/U3S2

dmesg | grep sound
