So I got a playlist all set up full of local music I'd copied over via USB. I don't know if I did something wrong (just got the phone a week ago and it's my first WP based device) but when I tried to play anything over my vehicle's bluetooth connection I got zero audio. The app looked like it was playing something but no audio came out. Volume was up, it works fine when not connected via bluetooth also. Is this just some sort of beta bug since I know the app is in beta right now? The normal "music & videos" app plays the songs just fine over the vehicle's bluetooth connection so I know it's not a problem with the connection itself, just something with the XBox Music app.
