Weird minor bug.
If you happen to have your PCs audio device disabled (Win10, USB speakers for instance) and try to start a shuffle/radio, PlexAmp basically just starts skipping through all your songs, a few a second. Obviously none of them play or anything, But should probably do something different than TRY to keep trying to play when it can’t, obviously (like maybe throw an error that there is no audio device, etc).
That’s all 
Thanks!
