Convert Analog Surround 4.0 output to stereo

I am running an external audio interface, an EVO4, and in Bazzite it shows up as "Analog surround 4.0 output". Bazzite lists it as having 4 speakers but it's really only 2. The Rear ones do nothing.

This is causing some audio issues in games as I cannot hear anything behind me. Is there a way to make sure that the EVO4 comes in stereo instead?

Solution

It only comes in either pro audio or 4.0 in the dropdown. I tried following this guide for a jank solution: https://writepermission.com/evo4-pulseaudio-profile.html

I am going to test it after dinner and see how it works. If it doesn't I will test Pro Audio.

What actually does Pro Audio do/mean?

the dropdown on the right should have some other audio modes - there might be one that is "stereo" or "2.0" output or something like that. worst case scenario, try using the "pro audio" setting, and that should present to games/etc as a stereo output. If none of that works you might be able to use pipewire to force the rear channels to loopback into the front channels but that would be kinda jank

pro audio basically just means you control each input and output as a separate interface iirc

Interesting. Iâm going to try that at some point. The guide in the link above seems to have worked for me now. I had to map the two useless channels to fake subwoofers, but audio in Ghost of Tsushima seems to work properly after that

Iâm doing some more testing before marking as done though
