pulseaudio problems again

[Jeremy Whiting]

Yes, it's intermittent for sure. I can go for days without having this
issue, or have it clear up within a few minutes sometimes. I think
Luke described the same problem on the list in February. Changing the
tlength requested in the code seems to make it work much better here
so far.
