Pipewire

install pipewire

pacman -S pipewire wireplumber pipewire-audio pipewire-alsa pipewire-pulse

needed for steam and gaming, remember to enable multilib

pacman -S lib32-pipewire lib32-libpulse

maybe needed for non onboard snd cards

pacman -S alsa-firmware

use pw-cli to find card information

forcing specific profiles for specific cards

This seems like a fucking broken mess at the moment, could not find a proper solution to set this in wireplumber. For now just using a bash script to run at startup of DE.

#!/bin/bash
for i in $(pactl list cards short|cut -d$'\t' -f2); do
  if [[ $i =~ alsa_card.pci ]]; then
    pactl set-card-profile alsa_card.pci-0000_06_00.0 output:analog-surround-21
  fi
  if [[ $i =~ SteelSeries_Arctis_Nova_Pro_Wireless ]]; then
    pactl set-card-profile alsa_card.usb-SteelSeries_Arctis_Nova_Pro_Wireless-00 output:iec958-stereo+input:mono-fallback
  fi
done
