So, in the web portal for my BLC I have set the N.Music source to 'Music' now, instead of 'Bluetooth'. Now, if I start playing from my music library using the B&O app, my system comes out of standby and it plays. If I press N.Music on my Beo4, my system starts playing whatever was last played. I can play, pause, skip tracks with my Beo4.
Unfortunately however, this seems to have stopped Spotify from working. If I use Spotify to play to my Essence (with either N.Music or N.Radio selected as the source on my system), it plays for about 10 seconds, but then the sound goes off. Spotify shows it is still playing, and the B&O app also shows that it is still playing, but no sound is heard.
So, it seems I can have either my media library or Spotify, but not both. Further experimentation required, it seems!
