I’m not sure if this applies, but you may need to go into your ATV4k and change the port to 9330. I had to do that to get the ATV4K working as a display.
Thanks Jim - I think you’re talking about using the AppleTV as a display like this. My goal is to use it as an audio endpoint, not as a roon display. Appreciate the feedback, in any case!
@Mark_Mitchell thanks for starting this thread. I have the exact same problem. AppleTV Model A1842 (32GB) gives me an AirPlay PIN whenever I try to transfer to it. I tried with tvOS 15.1, failed, upgraded to tvOS 15.2 and failed again.
Help Center Troubleshooting
I found a relevant Help Center article, FAQ: I’m having problems setting up AirPlay. This article is a year old, so it predates the September 2021 release of tvOS 15. I tried all three trouble shooting steps recommended in the article:
Update Your Firmware
I updated from tvOS 15.1 to tvOS 15.2. I continued to get PIN screens whenever I tried to play to the AppleTV.
Confirm Your Security Settings
The article instructs you to “go to Settings > AirPlay > Security > Require Device Verification and set verification to off.” In tvOS 15, this setting is not available. Similar settings are available in Settings > AirPlay and HomeKit > Allow Access. I opened this up as much as I could, and the problem persisted. I tried:
AirPlay: On
Allow Access: Everyone
Require Password: Off
Check Your Network
The AppleTV and Roon host are hardwired into my LAN. The Roon core sees the AppleTV right away. AirPlay works find with other devices, including HomePod Mini and Denon AVR-X4300H.
Hey @Mark_Mitchell, if the restrictions don’t help - on the Apple TV, if you go to Settings > AirPlay and click on Airplay Everyone, you will see Security below. This might show Require Code First Time Only but should be changed to a Password.
