Since tvOS beta 2, my Apple TV audio output is broken, it keeps changing output to my Sony TV speaker and Sony HT-A9 speaker, every fuxking 30s. Each time the audio output changes, Sony tv goes black. Impossible to watch anything. I tried everything, turns off volume control & control tv & receivers. Not working. Somehow I had found a way to stop the audio switching but I lost the function to use the Apple TV remote to turn on/off Sony TV & HY-A9 soundbar. I now have to use three remote respectively to turn on & off the 3 devices.

Today tvOS 17.2 beta 4 is out, and I have updated it. The problem still exists. 😭

Anyone have similar issues? Can you confirm it’s the beta firmware problem not problem of settings on my TV/soundbar ?
