I got a pair of Apple AirPods Pro. Was not even using them with Roon or anything else–just testing out the fit (poor in the right ear). I had music playing–Internet Radio via Roon–on the main system. Roon Core is on ROCK on a NUC. I use a MacBook Pro as a remote.
When I took the AirPod Pro out of my right ear, the music stopped. I then opened the computer/remote, looked at the Roon main screen, and did it again with the same result. The music stopped immediately when I pulled the Pod out of my ear.
The airpods have been set up on the MacBook Pro, but the first time this happened, the MacBook Pro was closed; are the Pods still connected when the laptop is closed? That must not matter, since I can think of no other way the AirPods could be controlling Roon.
I guess the most surprising thing is that the music that stopped was in a zone with a regular DAC. I have set up a zone, just for playing around, with “system output” as the end point so that I can send that out by BlueTooth, but the music wasn’t playing in that zone, and I wasn’t listening to it.
Anyway, this came as a surprise. I’m still not sure exactly what happened.
