MythTV can use PulseAudio, but the current implementation is
restricted to 2-channel audio. Go into the audio setup and scan for
devices. It will enumerate anything PulseAudio exposes, then
disable PulseAudio, and enumerate anything on the underlying ALSA.
The best option is to just not fiddle with anything, and let MythTV
disable PulseAudio during playback so it can use ALSA directly. You
can instead use the emulated ALSA:pulse device, or the native
PulseAudio device, however both have been known to cause loss of A/V
sync and other squirrely problems in the past.<br>

Most of the issues related to PulseAudio were related to A/V sync,
or the lack there of. There are complaints of noise issues when
stopping playback, but that is actually the result of MythTV
disabling Pulse to use ALSA for the duration of playback. At the
end of playback when MythTV resumes Pulse, all that buffered noise
from other applications comes flooding in. I don't know off hand
what would be causing that.<br>
