Hello,
In the last few days I had / wanted to switch to Pirewire for 3 Arch Linux installations from Pulseaudio.
I thought that would be complicated and cause problems. That was not the case at all.
So I want to share my path with you if anyone needs it.
Install Pipewire
pacman -S pipewire-pulse pipewire-alsa
The package pulseaudio-bluetooth may need to be uninstalled
pacman -R pulseaudio-bluetooth
Activate and start services
systemctl --user enable pipewire.service
systemctl --user start pipewire.service
systemctl --user enable pipewire-pulse.service
systemctl --user start pipewire-pulse.service
Maybe a reboot is needed for some function key on Laptops.
