Unfortunately, the audio quality is much worse now, and I had to roll back
without waiting to see if the reliability was improved. So:

Rev ?, HEAD built 2008-08-24: 
  streaming music is tolerable, speech is good
  after a few hours will lose it (not tracking encoding changes in mp3 frames?)
  and produce garbled audio

Rev 9849, HEAD built 2008-10-05: 
  streaming music is intolerable, speech is crackly
  don't know about reliability (had to roll back before waiting)

What was changed in the past 2 months? Are there any knobs to turn or other things
I can try?

FYI the mp3 stream is served with icecast2 and are 64kbps bit rate, 44.1khz sample rate, mono.
