Though I don't have these specific problems, I'm having general flakiness
with recording and playback that has been bugging me for a while.  I very
frequently get pops in playback, where I have to stop and playback again
to make sure the pops aren't actually in the recording (and they're not).
I also frequently get messages about dropped frames when a recording has
finished.  Finally, the play, record, and stop buttons just "feel"
unresponsive, taking half a second or so to kick in.  This is all with
the 1.1 branch.

What can be done to make audio i/o more solid and responsive?

I also noticed today a bug that affects recording: I can record fine in
stereo, but in mono it's totally corrupt and I can't explain exactly how.
It sounds something like an interleaving problem.
