Macbook Pro 2017 (13")
MacOS 10.13.5 (17F77)
When I pause a song on Spotify whilst using bluetooth earphones, audio is muted for every other application on the computer. For example if try to play a youtube video I can't hear anything. The mac volume level indicator is not muted though.
1. Start with spotify closed and play a youtube video - you can hear the audio fine.
2. Start spotify - can still hear youtube audio
3. Start playing a song on Spotify then pause it. Now all audio will be muted (also tried playing something in Audacity).
4. Play the song again on spotify - only whilst the song is playing can other computer audio be heard.
If I switch the the mac speakers then the problem stops. Only occurs with bluetooth earphones (my ones are Sennheiser CX 6.00BT).
Another way to stop problem is to quit spotify (Spotify -> Quit Spotify), though often I also have to reconnect my bluetooth earphones before audio starts working again.
I've tried reinstally spotify and deleting cache which doesn't help.
