Hi Colin, i think my release had include David's patchset.  I see
there're three patches about "Fast rewind", here's the link:
http://gstreamer-devel.966125.n4.nabble.com/Fighting-rewinds-pulseaudio-crash-update-td3248107.html.

The delay issue met based on my release build could not be fixed with
David's patch.
But i think it's quite like Ccrma's description in post "rewind and
underrun issues on start of playback".  If change the buffer size to
smaller value, the delay becomes short. I am not sure whether alsa is
playing silence data or just didnot start playback.

Thanks
