Not able to airplay phone call to Apple TV.
I have an Apple TV 4k and an iPhone XS.
I am not able to route phone calls via Airplay through the Apple TV.
I was on older system software versions on both and the Apple TV would not even show up when selecting the speaker output.
Now, with both devices on 13.4 it does show up and seems to try to connect when I select it. But it just falls back to internal iPhone speaker after 10 seconds or so.
Mirroring the iPhone during a call is not possible. I think that is deliberately prohibited.
I have to say that the Apple TV is connected via ethernet cable (via an Airport Extreme that also delivers the WiFi the iPhone is connected to).
WiFi and BT are active on the phone.
Any idea why this would not work?
