airplay: Harman Kardon speaker is connected but no sound on certain apps, only on Apple Music
Hi, I'm looking for help.
A Harman Kardon Citation 200 speaker is succesfully connected through Airplay. Louder/softer-light is visably working yet there is no sound. I've resetted many times, tried everything (different browsers) and this is so far the outcome: if I connect through Airplay no sound. But strangely enough, if I select Apple Music the speaker does work normally...
There must be something wrong with a setting in iOS I guess. Who can help me out?
Looking forward any solution.
