Your thanks should go to the mythbuntu folks ; they are the one who
created the packages installer and I just shamelessly took them
They have indicated that they will know build new version of mythtv
for all LTS revision + 6 months

If LPCM is greyed, it's not used. It keeps the content in case you do
use a source supporting LPCM and that way it keeps the previous status
of the LPCM checkbox ; otherwise you would have to recheck it each
time you change input which I found annoying

Checking the upmix box in the mythmusic settings is all you would
normally to play sound in 5.1

Weird that you get no sound.

Could you post the logs with -v audio ?

sounds like there is an issue with the ALSA drivers for your audio card

I wonder if we could add an option to automatically unmute the audio
card; putting this in the advanced like option, something like "unmute
audio card at startup" or something like that
