Sounds like two separate issues, but let's try and get to the bottom of it.

@shuyuxie are there any ERROR lines in ~/Library/Logs/Musicat/file.log ? I'm afraid that warning doesn't tell me much...

@northminds which format were you trying to play? Maybe send me the audio file to contact@slavbasharov.com
