Virtualized 2 track headphone surround input not recognized by 2018 Intel Mac Mini.

All my sounds coming through the HDMI port whether the source is HDMI natively or not. Then I have a toslink extractor converted to Dolby headphone using a Turtle Beach DSS. The format is LR 3.5 mm.

I don't think that the 2018 Mac Mini has a native toslink or 3.5 mm in cable. All it has is a headphone port , with two ears and one mouth.

On my thunderbolt 2 add-on device there is a microphone Port but it looks like a mono microphone port.

For some strange reason I can't get a stereo source into OBS other than USB.

This source is designed specifically to sound like surround sound when listening to it in headphones but is compatible with normal two track audio.

I know the Xbox One sounds fine because you could have that output in one of four headphone formats. I heard that the Nintendo Switch accepts USB based surround sound cards and automatically converts them to headphone sound as well as installing a mic that gets mixed.

But for all other systems all I get is the two-track sound instead of the headphone mixed surround sound.

I know I probably need a specific stereo input, because everything I plug in USB reads mono. Before it touches my computer I could get accurate surround sound but as soon as it touches the computer it cuts it down to mono.

Also wouldn't OBS recognize a stereo soundtrack by having a split sound meter bar indicating left track and right track?

I also tried using an old USB S-Video plus composite plus LR video cable by plugging in the audio cable only seems to give me mono audio even in that case.

What's going on? other than HDMI which I can't use, how do I get surround tracks in there?

By the way the game soundtrack I want inputted is only a two-track soundtrack that accurately appears to be surround sound when listened through headphones.

These are things I found out since I was working with tech support for both Apple and Best Buy.

Apparently there are issues of TRS versus TRRS. And it seems like no matter what you do the Apple only likes mono audio inputs.

Even the HDMI soundtrack extracted either directly once pumped into the Apple either more directly or through OBS both have mono soundtracks. And I believe I have the most obvious stereotest super r-type for the SNES background music 0f.

And when I try using an easy cap S video plus composite plus stereo left right, the USB microphone just gets a bunch of wine noise.

I think it's an Apple Mac system issue where it doesn't like stereo or higher sound as local inputs.

If that's the case then isn't there a way around it? I guess you could have two mono microphones and set one as the Left Channel and set one is the right Channel for the game music and sound effects. That's the only back door way I could think of.
