I am encountering a weird bluetooth issue and even after extensive googling I don’t have so much of a start of an idea what is going on. Here is the situation:
I have a Jabra elite 65t headset which is paired with both my mac (mid 2018 hardware, latest mojave version) and my iphone as I use it for listening on both devices. When I take them out of the case and they turn on they always connect to both devices if they are in range (no matter if the mac is open and running or in standby mode). So far all good. When my mac is open and I am working on it I can listen to music on either device, do calls with my phone through the bluetooth headset no problem. But when I am on the go and have my macbook in my backpack, pull out my earphones and they connect to both devices it is impossible to play music from my phone: The music player (tried apple music, spotify and soundcloud) indicates the music is playing but I don’t hear anything and after 0.5 seconds it switches back to paused. I can’t play anything until I open the macbook and disconnect the headphones/turn off bluetooth on the Mac. Sometimes my Mac also disconnects for a second and the reconnects with the headphones, in that case music also all of a sudden works again. At first I thought it is a spotify issue but it affects all audio output of the phone which is linked to a play/pause, it’s as if the mac would always send a pause signal when I start playing music on the phone.
I have tried to prevent my mac from auto connecting to bluetooth headsets with the defaults command for that but my headphones still autoconnect.
I have no idea what is going wrong, any ideas?
