Hmm.  That might do the job.  Looks like I'd have to do the 5.1 audio
decode in software on the Myth side instead of just passing it through
to the amp.  Wonder if there is a way to have Myth send multi-channel
audio to one alsa device and two channel to another....  I see config
options for PassThruDeviceOverride and PassThruOutputDevice, if those do
what they sound like they do I just might be in luck.  Looks like the
next weekend I don't have house full of grandkids I'll be tinkering.
