Today i installed PiCorPlayer 7 on my RPI3+ to play music from my LMS to my new bluetooth speaker (JBL BoomBox).

The install went smooth and also the pairing/connection to my BT-speaker is okay. Squeezelite is running and visible in LMS as a player.
I would expect to see the BT-speaker under Squeezelite Settings > Audio output device settings but i don't see it in the list.
I guess this is the reason i do not get any music output from my speakers.

I'm afraid i missed something in the configuration but cannot figure out what...

Any help would be appreciated.
