Not really a clutter--just made it look like there were a lot of Myth 
problems that weren't Myth.  :)

In that case, you probably aren't running PulseAudio, then.  The 
libpulse dependency is to allow Myth to be built in such a way that it 
can disable pulse when the user /is/ running Pulse.

So, now I don't know of any reason that you might lose audio--except, 
maybe, some lower-level/system configuration issue.
