[SOLVED] Pipewire doesn't detect any audio devices

Hello, I have recently tried moving from PulseAudio to PipeWire (Running KDE Plasma Wayland session so pipewire and pipewire-media-session were already installed btw). Here's what I did:

sudo pacman -S pipewire pipewire-pulse
sudo pacman -R pulseaudio-jack
sudo pacman -R pulseaudio-alsa
sudo pacman -S pipewire pipewire-pulse pipewire-media-session pipewire-alsa pipewire-jack
systemctl reboot

After the reboot no audio device was found except for Dummy Output. I did some Googling and found this post:
https://www.reddit.com/r/archlinux/comm … ces_found/
Following the solution to that post

sudo mv /etc/pipewire /tmp
sudo pacman -S pipewire pipewire-pulse pipewire-media-session
systemctl --user enable pipewire pipewire-pulse pipewire-media-session
systemctl --user restart pipewire pipewire-pulse pipewire-media-session

Did absolutely nothing, so I searched for other solutions with no success - the reason I'm here now
During my research I discovered that

pactl list cards

Outputs nothing

$ pactl list short sinks

                node.name = "auto_null"
                media.class = "Audio/Sink"de

I have also discovered that reinstalling pipewire packages only creates the directory of /etc/pipewire/ and all of its subdirectories except /etc/pipewire/media-session.d but absolutely no config files are created. Copying the config files from /usr/share/pipewire/ to /etc/pipewire and restarting doesn't help.
Reinstalling pulseaudio

sudo pacman -S pulseaudio-alsa pulseaudio pulseaudio-jack pulseaudio-bluetooth

Makes everything work great again
sof-firmware package is installed
Any ideas on how do I fix that?

Re: [SOLVED] Pipewire doesn't detect any audio devices

Try wireplumber instead of pipewire-media-session.

Re: [SOLVED] Pipewire doesn't detect any audio devices

Unfortunately I can't, because pipewire-media-session is a dependency of kwin. Is there a way to force install it or I'm better off not doing so since it could break kwin?

Re: [SOLVED] Pipewire doesn't detect any audio devices

Ok, so after my last message I went to the Multimedia and Games section of the forum and stumbled upon this issue:
https://bbs.archlinux.org/viewtopic.php?id=282148
The alsa-tools part immediately caught my attention so I quickly went through with pacman -Q and it turns out I didn't have alsa-firmware and alsa-utils installed

$ sudo pacman -S alsa-firmware alsa-utils

Then, before restarting the system I decided to reinstall all the pipewire packages (again, just in case)

$ sudo pacman -S pipewire pipewire-pulse pipewire-alsa pipewire-jack pipewire-media-session

After doing that, God knows why, my brain decides to type

$ sudo pacman -S wireplumber

And... it warns me about it being in conflict with pipewire-media-session. I proceed, but, to my surprise, this time it didn't warn me about pipewire-media-session being a dependency of kwin!
I restarted the system and everything works now. Seems like installing alsa packets did wonders to my system

Re: [SOLVED] Pipewire doesn't detect any audio devices

Just for the record: kwin actually depends on the pipewire-session-manager virtual package, which can be satisfied with either pipewire-media-session or wireplumber.
