---------------------------------------------------------------------- 
I've uploaded a patch, 13745.patch, which I hope will get this issue
fixed.

It applies two flags to the audiohook used in app_chanspy. First, it uses
the AST_AUDIOHOOK_TRIGGER_SYNC flag in order to use the
stream-synchronization logic introduced to solve issue
http://bugs.digium.com/view.php?id=13005. Then, I also
added a new flag, AST_AUDIOHOOK_SMALL_QUEUE. This way, if the situation is
like what I reproduced earlier today, stale audio will be flushed away and
the spy will hear the most recent audio possible.

Please give this a test and let me know if any sync issues still remain.
