I'm having an issue where audio drops out completely after playing a stream. It doesn't happen with every stream, but it will happen at some point during any session where four or five files are opened, or after changing a few channels in PVR.

This is occuring using SPDIF for normal and pass through audio. Device is an AMD Intel HD Audio integrated chip. (NVIDIA GT430 is installed but is _not_ being used for audio)

I'm not positive when the regression was introduced, I've been hoping it would be fixed on its own for atleast a few weeks. Audio was working fine before AE, and has been working since AE was added.

Here is a debug log where it occured: http://pastebin.com/85n6uaLm

Steps Taken:

1. Start XBMC
   
2. Go to PVR
   
3. Select Channel 22-1 (line 2310) (No errors occur, audio plays back fine)
   
4. Switch to channel 22-1 (line 2304) (Audio fails. video playback stutters. Audio fails for all subsequent streams)
   

Ubuntu 12.04, running XBMC over lightdm with no pulse-audio.
XBMC git revision 57d392d5b5d223027278a0c75b6fcf4815f5a12c
