Not too much really. I pair it, but after the initial pairing it is not connected, so I try to connect it. The connect button changes back and forth to disconnect and connect a few times and then it’s still not connected. The only thing I noticed is that KDE does not display it as an Audio Device, but as Other Device. My speaker is detected as an Audio Device.
Sounds very straight forward. Do you have a samba docker container running on your server or how do you do that?
