It was enabled so now I disabled it. I'm not even sure why it was 
enabled in the first place, it sounds useless and is documented as "Say 
N if not sure." Haven't had any issues to far.

The main thing I was hoping BMQ might be able to fix is the short sound 
dropout when seeking in MPV. Meaning sound dropping out in other 
applications while seeking in a video in MPV. And guess what, it indeed 
fixes it. I had similar audio issues many years ago, and back then BFQ 
was able to fix them.

Thanks for the help!
