you are using a stereo output, what is there to upmix?
your asound.conf downmix, not upmix.
And myth will properly downmix all content from surround sound to
stereo no worries (and do so better than your asound.conf would)
If you want to use surround sound, select ALSA:surround51 or
something, and set your audio speakers in myth as 5.1

you're missing some logs there, and use -v audio

i thought that would be the case ...
But earlier you said you were using stereo audio to an analog TV... so
what's the go with downmixing like you do ?

you can do all that with pulse, and even application not pulse aware
would work too...
