Apple Tv 4K 5.1 Channel Issue

I've my apple tv hooked up to my soundbars ARC port and everything works absolutely fine when it comes to playing Dolby Atmos content but when it comes to 5.1 Dolby Surround channel Amazon Prime just simply seems to be not working. And it works only if I turn off Dolby Atmos from setting and switch it to 5.1 setting and then all the 5.1 content works just fine but then again what's the point of having Dolby atoms if I just have to keep switching On/Off Atmos for the Apple TV to recognize 5.1 Surround Sound.

My soundbar has a display which shows if its Dolby Atmos or surround sound but with apple tv it only shows Atmos logo and only after switching off atoms does it show surround logo.

Anyone has any idea about this ?

Apple TV 4K, tvOS 15

Yeah, I’m having the same problem. All 5.1 media is getting sent as lpcm and I understand that can be 5.1 but I am not hearing any variations of audio from the satellites speakers. Everything just sounds like a stereo spread. Haven’t came across 1 5.1 title that actually sounds like a true 5.1 mix. Atmos works perfectly.

Your indicator display may show Dolby Digital 5.1 differently from PCM 5.1, but both are 5.1.
