Im on openSuse Leap 15.5 and I moved to Pipewire back when I had 15.3 I believe. I had that issue where all output devices/input devices got smashed together. I stuck with it for couple of months and I believe the later versions fixed that. Now I am painfree and never bother with audio ever again. I used to have frequent pulseaudio crashes which is why I switched over to pipewire.
