No Audio playback in Basehead suddenly!!

I've been using Basehead for a few years now and have suddenly run into a new problem.  No sound on playback of audio files within Basehead.  Everything else seems to work.  And I'm getting audio from all other applications.  My audio driver settings within Basehead are as they should be.  And the volume slider in Basehead is up all the way.   I can't figure out how to get audio working again. 

Anyone else run into this?

Please help.  Thanks.
