--- Comment #6 from David Mansfield <freedesktop-bugzilla at dm.cobite.com> ---
Can someone "in the know" comment on what this part of the diff means:

-D: [pulseaudio] alsa-sink.c: setting avail_min=87319
+D: [pulseaudio] alsa-sink.c: setting avail_min=1

As I understand, for glitch-free audio, the playback stream should only start
when at least two buffers are full.  Is this saying that it will start
immediately? (1 byte?)

Perhaps that is the issue. 

In my specific case, the audio data to "play" is coming from an RTP stream, and
is therefore paced by some external network client, and perhaps the stream is
being kicked off too soon, and/or not rebuffering correctly on underrun.

How can I diagnose this further?
