Public bug reported:
I think this is related or even the same as Bug #494099. After sound settings
setup in 5.1 or 7.1 mode start music playback (I use Banshee most frequently,
but also tried in Rhythmbox). If tracks are swithed automatically one after
another in playlist (in random mode), for some time everything is OK. If I
switch to next track manually even once, subwoofer channel disappears and I
have to set sound settings again to some value and then again to 5.1 to enable
it. The most interesting thing - subwoofer channel disappear in Rhythmbox
doesn't affect Banshee when they are running at the same time. After disappear
in Banshee, I launched VLC with a movie and subwoofer channel was active there
without any setup.
I have 2 outputs (analog and digital) on default sound card and several sound
inputs on 3 different devices. Only one of inputs is set up as active.
I have 12.04 upgraded from 11.10 (don't remember which of 11.04 or 11.10 was
installed as new OS).
