I had checked this immediately with me, there does not occur, but does what it should

That is correct. pulseaudio is only started when an application (Kodi) wants to access it.

Quote:So, in the end, this seems to be the real issue cause: pulseaudio not running yet when trying to connect the BT device.
If so, given this should be the normal behaviour of the USERRUN script, I'm wondering how the BT connection works fine on your systems: maybe you're using something different from pulseaudio?

Actually I don't understand why it doesn't work for you. pulseaudio doesn't care which audio sinks are already present at startup. It always takes the default sink first, which can also be a dummy sink. And if another sink with a higher priority is added later (in your case a bt headset) it will use it.

At least this is how it works with my installations

Of course you should use the pulseaudio default device in Kodi and not explicitly your headset.

I just checked this again:
- System started
- In Kodi Audio set to Pulseaudio (default) -> sound is routed to the TV
- BT speakers turned on (were miraculously connected automatically) -> sound now arrives on the BT speakers
As it should be
