I worked on this problem yesterday evening and figured out how to get audio playing in Mythtv, this is more of workaround than solution.
I tried first to add EXPERIMENTALLY_ALLOW_PULSE_AUDIO=1 in .bashrc and .profile, but that did not work.
So i added that in mythfrontend script and since then i live TV is having sound in MythTV.
FYI, i use generic ubuntu (with gnome) with installed mythtv on top.
