EndeavourOS is using Pipewire per default up from Atlantis Release, but in case you do not want to use Pipewire, or you need to use Pulseaudio in case apps you need to use only work with PulseAudio, you can switch back to it:
sudo pacman -S pulseaudio
what will replace pipewire-pulse
In addition, you may need:
sudo pacman -S pulseaudio-alsa pulseaudio-jack pulseaudio-bluetooth
Depending on what is installed on your system it will be needed to remove some Pipewire packages before installing pulseaudio, or it will five you dependency errors:
sudo pacman -S jack2 pulseaudio-alsa pulseaudio-jack
It is currently possible again to completely remove pipewire too as I just tested (January 2023):
In this case you could use -Rc to take the dependencies with it as I want exactly this, but keep care to check the exact output to not remove half the system with it !!
sudo pacman -Rc pipewire
I would recommend using something like this instead:
sudo pacman -R pipewire wireplumber libwireplumber gst-plugin-pipewire
To use pulseaudio simply reboot your system or if you can not do that unload pipewire and load pulseaudio:
systemctl --user stop pipewire-pulse.service
systemctl --user start pulseaudio
inxi -Aaz will show if it is all working fine:
For the other way around switching from Pulseaudio to Pipewire:
