Question PC to Atmos receiver over HDMI no centre speaker?

[Stewart_2]

So I have a PC with a Vega64 GPU with HDMI out into my Atmos receiver. The PC is setup for Atmos Dolby but when I playback YouTube etc the voices are spread over the front stereo pair and not the centre speaker? The Atmos amp is showing the audio input signal as Atmos. I know this is wrong cos I have a Creative Labs 3D Recon into 5.1 speakers on another system and that works fine so it has to be this PC and the AMD drivers ???

If I use a DAW (music production) or voicemeeter I can get it to work properly.

Any advice would be appreciated

I'm unfamiliar with Atmos, but is the audio source (youtube) already encoded as atmos? If not, the system (in this case the audio part of the GPU driver) will have to make assumptions about how to encode it as atmos, and shoving it into stereo might be its default, maybe because the original youtube audio was only in stereo.
My recommendation is, let the PC pick the encoding based on the audio source, and if you want to do surround faking, let the amplifier built in functions do that, not the PC.

YouTube now supports limited surround (5.1) but for films etc I use JRiver Media Centre. Strange but when PC set to stereo I get surround but amp says its a stereo input the output is never Atmos except when using JRiver and source media is Atmos or PC set to Atmos. I can only think it has something to do with the Vega64 hardware driver support but could never find any info online

See if you can set it up for 'all channel surround'. AFAIK, youtube videos are not atmos, so you might have to tweak the setup to get that center channel working.
