Airplay icon missing after connecting Apple TV 4
Hi.
Until last week I could air play music from my MBP and Mac Pro to our Yamaha receiver & entertainment system. I could connect to it via bluetooth. But this weekI can't. The icon has disappeared, as has the list of commonly used bluetooth devices, such as the Yamaha receiver, bluetooth speaker, phones etc.
Last weekend I connected an Apple TV 4 that my folks were done with, connected the 2 Macs, watched a movie just fine, but now there's no airplay icon on my music app. And no way to connect to the receiver via bluetooth.
I've restarted everything, signed out of apple TV and removed it. Everything is on the same network.
All the other devices - phones and ipads can still connect via bluetooth to the Yamaha.
Can anyone help? Thanks
