[mythtv] lose of audio after editing cut list

[Vinton Coffman]

Seems very repeatable.  After entering edit mode and load cut list, I 
edit several of the cut points.  I then exit edit mode hit hitting M 
again.  At this point, the video begins playing without any audio.  To 
recover I just exit the video playback and start again and the sound is 
back.  This is a pvr-250 file captured at 720 x 480 4/8 Mbps and 
default audio.  Built with native alsa support and native lirc support. 
  Loss of sound only seems to occur after editing.  It normally plays 
with no perceivable differences from beginning to end.

Here are the messages from mythfrontend for the last two instances of 
this.
