[Solved] Audio not working [Wireplumber fails to start]

Hi, I've had arch working quite well for a while now, and recently managed to goof up my audio. I noticed wireplumber no longer starts:

So I must have partially updated at some point and broke it, but

pacman -Syyu

with updated mirrors and from chroot hasn't resolved it, so I'm not sure what to do.

I was however able to verify that the speakers can emit sound by using

Any insight/help would be greatly appreciated

Re: [Solved] Audio not working [Wireplumber fails to start]

Update your system, wireplumber should not look at a 0.4 version

Other than that

pacman -Qs 'wire'
pacman -Qikk wireplumber

Is that set of flags missing anything?

Re: [Solved] Audio not working [Wireplumber fails to start]

Oh jeez, ok.

Somehow I had two binaries for wireplumber:

❯ whereis wireplumber
wireplumber: /usr/bin/wireplumber /usr/local/bin/wireplumber /usr/share/wireplumber

And /usr/bin/ contained 0.5-1, which runs as expected. Replacing the one in local/bin with it returned things to normal

Thanks for taking a look, V1del!

Re: [Solved] Audio not working [Wireplumber fails to start]

You should not have any binaries in /usr/local unless you run unpackaged compiles, you should rid yourself of the copy in /usr/local or you'll have the issue again

Re: [Solved] Audio not working [Wireplumber fails to start]

Thanks for highlighting that, I guess there's something else needs doing because keeping it in the right place (/usr/bin/ rather than /usr/local/bin) causes it to fail on startup:

Granted I can run wireplumber manually and that's fine, but I would like this to just work. It's not clear to me why it starts but then exits in systemd

EDIT: Actually, there's this too:

❯ systemctl --user status wireplumber
× wireplumber.service - Multimedia Service Session Manager
     Loaded: loaded (/usr/local/lib/systemd/user/wireplumber.service; enabled; preset: enabled)

        CPU: 697us

Apr 06 19:51:25 mechanicus systemd[937]: Failed to start Multimedia Service Session Manager.

so it's still looking for wireplumber in /usr/local/bin, how can I tell my system to find the binary in /usr/bin/ instead?

EDIT 2: Got it, was able to edit ExecStart's value in ~/.config/systemd/user/pipewire-session-manager.service to resolve this part

Re: [Solved] Audio not working [Wireplumber fails to start]

Why does any of that exist? None of those should be present on a normal install, no binaries in /usr/local and no custom service files in ~/.config/systemd/user/pipewire-session-manager.service either.

It sounds like you experimented with a custom/from source install of wireplumber/pipewire for some reason and now have residues scattered around that conflict with package defaults.

Re: [Solved] Audio not working [Wireplumber fails to start]

That must be it exactly. I wasn't aware of how building from source and package managers use different install directories (seems obvious now) so this is how I pay for being frivolous with that I guess
