As it so happens, I made a change last Friday to handle this type of 
audio error. I have now posted the latest release with this change 

The change will try to switch to another audio track when this happens. 
If none is available it will disable audio, so the video will go silent. 
You can try to reactivate audio by using the audio track (icon of an 
ear) in the player.
