Description
When 5.1 sound is selected in Setup>General Settings, the OS X frontend sees the AC3 audio rapidly switch back and forth between stereo or mono and 6 channels (sometimes many times per frame) generating loud static: 2010-06-04 20:01:15.884 AFD: AC3 changed from 6 to 2 channels (frame 51) 2010-06-04 20:01:15.895 AFD: AC3 changed from 2 to 6 channels (frame 51) 2010-06-04 20:01:15.932 AFD: AC3 changed from 6 to 2 channels (frame 53) 2010-06-04 20:01:15.933 AFD: AC3 changed from 2 to 6 channels (frame 53)
This behavior is observed when playing back any recording from any channel, as well as DVD and Blu-ray rips via MythVideo?.
More complete log attached, as well as sample clips recorded from PBS and CBS.

Remove AC3 channel parsing in NVP ; this may have been required at some stage, but this is something ffmpeg already does. This should fix ticket #8532. Original patch by Mark Spieth.
Please try with revision r24987 and report if you're still having the problem (it shouldn't the bit of code creating your issue in now completely gone)

I tried again on a number of recordings and rips using r25019. Unfortunately, I still get the same behavior - see log attached.
