so you are using 5.1 audio out, earlier you said you were using an
analog TV only, which I assume has stereo only.

The problem with your current solution, is that in myth you do not get
real 5.1 audio when you play 5.1 content. You do get sound on all
speakers but that's not discrete audio.

If you set myth to use ALSA:dmix6 , set the speakers as 5.1

You should get audio even if other applications are running, but
you'll get proper 5.1 audio when needs be, and properly upmixed
(similar to DTS-ES) stereo to 5.1 audio
