Music info and control
Some bands/watches have support for music. This can vary in features, like:
- controlling playback
- playback toggle (play/stop)
- forward/backwards (fast forward/rewind)
- control volume
- receive track info (name)
For basic functionality (playback start/stop) you typically, you do not need to do much settings, but you can set preferred music player in Settings → Prefered Audioplayer.
For advanced functions like Track info or Volume control, you have to make sure that you put your audio player into list of applications allowed to send notifications.
To test if the music info is working, you can use Debug → Set Music Info.
