Apple TV switching HDMI input automatically in Sony TV
I have an Apple TV 4k (2nd gen) and a Sony X90L. My AV receiver is an Integra DRX 3.4.
What happens is when I change audio output from TV speakers to audio system (AV receiver) in the Sony, the Apple TV force switches the input to HDMI 3 (which is the eArc slot). I then have to grab the sony remote to switch input back to the input where the Apple TV is connected to, in the case HDMI input 2. It would automatically switch inputs twice until the output is set to audio system.
I've chatted with Sony support and we were able to isolate the issue that it only occurs when the Apple TV is connected. No other devices I have such as the 4k player, PS5, or Nintendo Switch force switches the input when changing audio output.
Is anyone else experiencing this issue with their Apple TV when connected to a Sony TV with an AV receiver or a soundbar using earc/arc? Any thoughts or solutions would be appreciated.
