Roon 1.7 fails with AppleTV device, due to Airplay Passcode prompts

Hello @Dean_Wette, In the AirPlay settings on your AppleTV, set the access control to require a password. Enter a password on the AppleTV when it asks you to set up a new password. Once you have done this, try enabling the AppleTV zone in Room again. When prompted, enter the password you set on the AppleTV. -John
