I have seen this before, but not recently. Only the rear speaker tracks 
were playing. It has happened once or twice with recordings, although 
not lately. Previously when it happened I have switched to the other 
audio track. At the time there was no audio description so that worked 
for me. I suspect something messed up at the broadcast station. 
Sometimes it sorted itself out after a commercial break.
