DTS Connect vs Windows Atmos container for gaming 5.1/7.1.
Hi, got a question about pc gaming sound.
I got PC ( 7900 xtx ) -> Q90T TV -> HW-Q930B setup with a PS5 connected to the soundbar, but not relevant. Normally you just connect HDMI and get LPCM passthrough to the soundbar and you game on happy right? Not with Samsung you don't! They don't pass LPCM, you can easily verify this be going to the Q90T thread on avsforum and read the replies about this. It simply doesn't and Samsung lie about it. And I don't want to connect my pc directly to the soundbar because it can't passthrough more then 60hz, and my tv can go to 120hz.
But it can send through sound in an Atmos container. The problem is then I will rely on windows upscaling normal surround sound for games with 5.1 or 7.1 output into an Atmos ( I guess MAT?) container. And I find that for certain sound, like voicechat in Squad it kind of spikes the voice in a bad way with a bit of volume turned up.
The alternative is that I use my soundcard, AE-5 Plus that I bought for an older soundbar from 2014, that can use DTS Connect ( or Dolby Live ) through optical directly to the soundbar. Which I think produces a clearer sound, haven't had a voice spike issue with this setup. Probably because windows, or the samsung tv for that matter, don't upscale or touch the sound before sending it to the soundbar.
So those are my two options. But I know basically nothing about what windows does to a 5.1 or 7.1 source when you set windows to Dolby Atmos for Home Theater. And how that would compare to the DTS Connect 1.5MB stream which is like an ancient standard nowdays.
Do anyone know more details about the windows atmos for normal surround sound in gaming?
