Xbox Game Bar doesn't record audio through THX Spatial Audio

I had the same problem with Nvidia, but managed to find a solution. However, that same solution doesn't seem to work with Game Bar. I really don't want to switch away from Spatial Audio, so I need a fix of some kind. Since Spatial Audio doesn't work, does anyone know how to get Game Bar to recognize audio from an output other than the default? Perhaps the regular USB Sound Card?
