Alrighty y’all, here is an interesting one for you:

I own a Samsung Q90R and a new Apple TV 4K 2022 model. It’s plugged in directly via HDMI with an optical running from the TV to an AVR.

I recently unboxed the new Apple TV and set it up. Everything worked great for a couple of days with no issues. All of a sudden I noticed that there was no sound coming from any Apple TV activity (sound came from TV menu options). I went to restart the Apple TV and the whole screen turned pink/purple. Unplugging and plugging the power resulted in the same pink/purple screen appearing. I found that I could reset everything by unplugging the HDMI cable and allowing my TV to rediscover the Apple TV. However, I have figured out that if HDR is enabled on the Apple TV, I won’t get sound and will get the pink/purple screen. As soon as HDR is turned off, my sound returns. I can leave it on SDR and turn on match content. This will allow me to play HDR content with the following caveats:

1.) The Apple TV apps will no longer tell me if something is HDR

2.) My home menu looks a little off

3.) My shows now have the soap opera effect.

I did switch out the HDMI (confirmed it’s high speed) and plugged into a different TV (HDR compatible Sony.)

This leads me to believe the Apple TV and Samsung aren’t playing nice together. I did have an Apple TV 4K 2021 plugged in through the AVR to the TV and had no issues. However I changed my connections with the new Apple TV since my AVR does not have HDR10+ pass through.

Any thoughts here?

I have a Samsung Q90 TV with a Samsung Soundbar setup with my Apple TV 4k 126GB model. I've been having sound issues ever since the tvOS 16.1.1 update. I get a radio-like static noise every 20-30 minutes and last for about 2-3 seconds, other times the sound just cuts out completely (depending on which app I'm watching). I don't know if you're experiencing that as well - sounds like maybe you are...? I get a green screen (not pink/purple) when booting up my Apple TV, right before my Samsung TV and Soundbar discover the Apple TV has been turned on - that didn't happen until tvOS 16.1.1 either.

My two other Apple TV 4k's (2021 models) do not have any sound issues, they are both on tvOS 16.1. I tested by hooking them up and using them each for a day on my Samsung setup.

I got the exact same issue and setup. I upgraded my hdmi cables and the static sounds became 2-3 seconds of silence instead.
Did you find a fix? I'm considering to get a new Apple TV on warranty.

I don't have the same TV as you but I also have a Samsung TV (Q80T) and have the new ATV4K 2022 model hooked up directly to my TV using eARC for audio.

I have audio issues on tvOS 16.2 where any audio that is Dolby Atmos drops out periodically over eARC. I had no problems when my previous ATV4K (2021 model) was connected directly to my receiver, however, I want HDR10+ with the new AppleTV so I need to connect it directly to the TV. After upgrading my 2021 model to tvOS 16.2 I noticed that I started to have audio dropouts with Atmos content. This issue has continued with my new 2022 model. I've found setting the eARC mode on my TV to Auto instead of Passthrough alleviates both the frequency and the length of the audio drop outs so I can use that as a workaround until the issue is fixed. There was an apple discussions thread I found where others with different equipment are reporting the same issue. Hopefully this gets resolved with an update to tvOS as none of my other devices (PS5 and Amazon fire tv stick 4k max) have audio dropouts with Atmos audio using eARC.

As for the HDR issue you are experiencing, one thing I would make sure to check is that Input signal Plus is enabled for the HDMI port you've connected the Apple TV to. If you notice the soap opera effect, make sure to turn off motion settings on the TV both while SDR content is playing and when HDR content is playing (the TV saves settings specific for if you are viewing HDR content). Finally, I noticed you stated you had done this and I would recommend keeping the aTV to 4K SDR and then enable match range and match frame rate. This uses less bandwidth most of the time because typically HDR content is 4K/24p and is probably why you noticed fewer issues when using the match content feature. As for verifying if you are receiving an HDR signal, unfortunately you will need to do this on the TV itself (easiest way is to hit the home button and scroll over to the TV quick settings where the picture mode name will say HDR in the corner when HDR is engaged...you can also select the input again which will engage the info banner on the TV).

Most modern cheaper TVs only seem to do STERO audio out those tiny speakers! Unless you put a HDR receivers in, connect the Apple TV to in and out to TV from that receiver out HDMI 2.1 out!
