@Chais @n3cr0 how do you replicate that with pipewire anyway? Sure, you can rig up the nodes and all, but are games actually outputting surround nowadays, or how do you benefit from all that work?
Exactly. You set up the virtual sink for 5.1 output and make pipewire convolute the signal with a suitable impulse response to turn it into a stereo signal that sounds like it's coming from the correct direction.
@Chais do games actually output 5.1 nowadays? Most of those I know use libraries like steamaudio, which simulates it using in-app hrtf, mixing the signal on its own
It depends on the game. I have 5.1 speakers on my computer and can hear things behind me in some games, but not others.
At least I can play games and get directional audio. Beyond that I care little how they achieve it.
