[mythtv] Splitting out audio output code in preparation for native ALSA support

[John Hurliman]

Really looking forward to S/PDIF output on the i810 chipset. If there's
anything I can do to help out e-mail me. I haven't taken a look at the
audio code in myth; do mythtv and mythmusic use the same audio output
code?
