So to recap a little on the fighting rewinds issue - the one that makes
pulseaudio crash due to spending too much time in RT prio, and with the
pulseaudio log filled with rewinds.
A month ago I provided five patches in total, two in gstreamer[1] and
three in pulseaudio.
GStreamer #1: we have the "don't start the stream until we have written
some samples" - this fix is in gstreamer HEAD, committed by Wim Taymans.
GStreamer #2: send larger packages by removing a strange limit to
gstreamer's "segment size". This fix has been posted to the
gstreamer-devel mailinglist, but not committed AFAIK. I'm attaching a
version of the patch which has proper git headers and against git head.
Both GStreamer fixes have recently been uploaded to Ubuntu Natty, the
development version of Ubuntu.
PulseAudio #1 and #2: I believe these should be applied to PulseAudio
upstream.
PulseAudio #3: A person with alias h31 helped out here, and noticed this
patch was the one causing a regression in Skype. While I haven't exactly
figured out why, I do notice that this patch could cause problems for
very short samples. So let's drop this one for the time being.
For reference I resend the three patches (one in GStreamer, two in
pulseaudio) that I would like to see applied.

one.
