Description of Issue
When playing music via Roon. Usually the app on my Mac, always to Sonos speakers or Sonos Amps. If a call comes in on my iPhone, or if I start or join a Zoom meeting, the music stops playing.
The first thing to check would be your iOS notification settings for each app causing issues.
Another thing to test, does this happen on other streaming services? If not, take a look at mirroring the specific settings you have for that streaming service, and apply it to Roon on the affected device
From your reply above, it sounds like you’re not wanting Roon to be connected to your Airpods. Which device are your airpods connected to? It could be a situation where Roon is connected to the same device, playing music to the output of the device which is connected to your airpods, making your airpods the final endpoint for Roon.
I would take a look at the settings of the device your airpods are connected to. You could also take a look at your Roon Settings> Audio and disable the device connected to the airpods.
If you could test this and let me know the outcome that would be helpful, and let me know if I’ve understood your situation properly
