I haven't tested Airplay functionality (need to procure device), but Chromecast devices aren't detected.

With build 3517, MMM displays any chromecast devices that are online, but:
a) if playback is stopped, and the user enables casting, and then initiates playback
--> all tracks are skipped with an unable to decode track error
b) if playback is ongoing, and the user enables casting during playback
--> playback works (e.g. on track 1), but clicking 'Next' to advance to the next track (2) causes a decoding error for the track (2) and then playback works for the following track (3). This pattern continues for all tracks.

In the attached debug log, you can see:
- successful local playback of all tracks
- (case a) failed playback of all tracks (for 2 different chromecast devices)
- (case b) failed playback of every second track
