this breaks parsing of some AC3 streams. For example 
ac3_parsing_errors_rev12894.mpg in incoming.

I'm not sure if this is the actual changeset which is to blame. It is 
the first which introduces
"frame sync error" and "incomplete frame" messages. But those are only 
at the start of the file while the beeps with current trunk are later 
in the file.

Playback of that sample is broken from 13579 til 13653. Revision 13654 
fixes playback but introduces nasty beeps after each frame sync error.
