Pulseaudio/A2DP needs reconnect to work

Hey folks,

I have a problem with one of my bluetooth headsets. All of them automatically connect, switch to a2dp and change the pulseaudio sink.
However, using my JBL Everest 750NC headset, I need to manually disconnect and then reconnect the a2dp profile in order to actually get sound out of it.
When the headset is initially connected, blueman shows it as connected, pavucontrol says the a2dp profile is chosen and music stops coming from my laptop speakers. Unfortunately, there is no sound from my headset either. I then disconnect and reconnect the headset using blueman and magically, the sound works as expected.
Do you have any idea where I could look for error messages or even know the problem? This is kinda annoying… This issue does only happen with this specific headset. Other ones are working just fine. So, I imagine some timing related problem. Still, I don't know where to look or even fix this issue.

Here some debug output during initial connect and then reconnect. I cannot spot any differences in this behavior.
