Ok, I've spent a few hours now playing with the audio code, and still
can't locate what happens when a channel is changed.  It seems as if the
audio code is only initalized once in the NuppelRecorder, and that
although the audio is mutted and unmuted while the channel changes --
it's only effecting the mixer, and thus doesn't really do anything to
the audio.

my guess is that the audio gets out of sync (as in what is being
recorded) as the channel changes.  First off, does anyone else
experience this?  Secondly, I've been trying to track down the code that
deals with the NuppelRecorder and how it changes channels but have been
uncessessfull.  Does anyone have any idea of what file/function/methods
are relevant here?
