Bluetooth disconnects

[Nachteule]

In my opinion, you are mistaken here

At least with all my installations this is not the case. I can switch on my BT speakers whenever I want, there is never a new pulseaudio instance started. That would be totally absurd too

Here it works like this:

1) bluez is started long before Kodi and pulseaudio.
2) when Kodi starts, the PA libraries cause the pulseaudio daemon to be loaded
3) at some point I can turn on the BT speakers, they are then properly integrated

No respawn of pulseaudio daemon or whatever

I have no idea anymore why this should not work for you
