 Priority:  minor                    |   Milestone:  unknown

-------------------------------------+--------------------------------------
 During video playback, sound suddenly disappears, attempt to exit playback
 causes deadlock. This issue is intermittent and happens once out of 5-6
 videos watched. Video is a recording from HDPVR.

 Attaching gdb and then detaching seems to get frontend back to working
 state.

 Attaching frontend log (general,playback,audio logging), and backtrace
 from gdb.

 Sound card: Sound Blaster MP3+
 Processor: AMD Athlon(tm) 7750 Dual-Core Processor
 Video Card: nVidia Corporation D9M-20 [GeForce 9400 GT] (rev a1)
