Headset option missing from desktop

When I look at audio device options in the taskbar config popup and 'select a sound input' I only see speakers. Both my speakers and headset are plugged in. I have an MSI MAG X570 Tomahawk Wifi - it has 5 audio jacks - 3 for speakers and 2 for headset (output + mic). Audio is coming out of both speakers and headset, so I can turn the speakers on or turn them off and put the headset on. That's great, except the audio is not being channeled correctly by Windows, if I put a movie on with 5.1 sound, I can't hear some of the channels in the headset. And there is no way to select headset because Windows doesn't have a headset option.

When I go into device manager, here's what I see...

Those headset options are for my old headset, which was a USB headset, I now have a twin-jack headset. I've removed the usb dongle, I've even removed the devices in device manager and checked for changes. The Razer USB Sound Card just gets added back in by Windows. I'm not sure what to do here.

It's useful to have both speakers and headset running at the same time because sometimes I will have both the headset on and the speakers running. But how do i know if audio is working correctly when some sources don't play correctly. And why was there a Headset option with my old headset and not my new one?
