@benwiz Sorry, I just saw your comment. I won't be able to give you much help: I use mopidy with snapcast, so I usually don't play music locally (I set up mopidy so that it plays to the snapcast fifo). Perhaps you need to customize the audio section of the mopidy config.
Anyway, I advise you not to use my image, it is currently not very well designed, and quite specific to my needs.
I can view the UI at
localhost:6680 on my mac. And I can view and change the track playing via
mpc in the command line. But I can't hear any audio. How do I set it up so that audio comes through?
