Apple TV 4K 2021 / A2169 IPSW restore?

Hey folks,

I'm running out of Options to fix my current HomePod audio issue.

My current TV setup as follows: Philips 70PUS7805/12 Apple TV 4K 2. Gen A2169 tvOS 15.1 Beta 19J5567a 2x HomePod OG as stereo pair Active Apple Developer Account

Using the HomePods for Output isn't working anymore. Must've stopped from Beta 2 to 3 / 4. Reset of HomePods, Apple TV etc. has been done a couple of times. Even tried it on another TV. Streaming Music from the iPhone to the Apple TV: sounds coming via HomePods fine Streaming Video from the iPhone to the Apple TV: video via TV shows up, but no sound Setting the HomePods as temporary audio output: actual sound of series / movies watched via Apple TV Netflix / Apple TV+ etc. apps works, but without menu clicking sounds etc. 

So yet think the last resort is restoring the IPSW via Apple Configurator 2 but when I drag & drop the file onto the Apple TV this funny thing asks me to connect the A2169 via USB ... 

Any suggestions for a solution?

Many thanks in advance! pafedu
