I have the same issue with no audio from any source. Weird part is that when Waze app speaks, the music can be heard. It's as if the audio is muted but when Waze speaks, it temporarily unmutes the music. My temporary "fix" until I can pull over is to keep hitting the main menu button which unmutes the music for about 1 second, I've gotten pretty good at tapping that button. This is a software issue and should have been fixed a LONG time ago.
