Hi all,
Since upgrading to Ubuntu Precise and pulling the latest GIT from the PVR branch (although I've tried the normal branch too), I've had major problems with audio, in that it generally doesn't work!
No matter what I try to play, either PVR stuff from my TVHeadend, or static .mpg .avi, etc from my drive the sound sometimes doesn't work (well, the majority of the time it doesn't work).
When the audio doesn't work the video playback is also choppy, but I assume thats because its trying to sync tv/sound together.

Details:
XBMC (12.0-ALPHA3 Git:20120601-cdbea16), Platform: Linux (Ubuntu 12.04 LTS, 3.2.0-24-generic i686). Built on Jun 6 2012

00:1b.0 Audio device: Intel Corporation 82801H (ICH8 Family) HD Audio Controller (rev 02)


Debug log is at: http://xbmclogs.com/show.php?id=3357
To reproduce, power up system, let it boot and load EPG info, etc. Then select a channel to watch, or a media to play. Almost 9 times out of 10 the audio fails and to try again you reboot the machine and try it again!

The bit of the debug log that I think is relevant is:

PS: When using XBMC itself, the navigation sound (bubbles nav.wav, etc) all work fine before trying video. If I try to playback something and it fails then I also don't get any navigation sounds afterwards until a reboot.

Help! Many thanks in advance for anyone who can give me a nudge in the right direction here.

If you have them enabled, try disabling "Adjust display refresh rate to match video" and "Sync playback to display".

Thanks for the advice, this wasn't it though.

What I've done is downloaded the xbmc live and did a total re-install, so I believe this is something to do with Ubuntu PRECISE, not XBMC itself, as back to Oneric and all is well again.
