Fedora 35: Fixing PipeWire, WirePlumber missing sinks/targets

Framework Laptop 13
1

I needed to automatically switch to HDMI Audio once it was plugged in.
Unfortunately, PipeWire and WirePlumber can only detect one target.

$ pw-cat -p --list-targets
Available targets ("*" denotes default): 
*       39: description="Built-in Audio" prio=1000

$ wpctl status
PipeWire 'pipewire-0' [0.3.38, user@fedora, cookie:2305481597]

The solution was to modify /usr/share/wireplumber/main.lua.d/50-alsa-config.lua and apply the following lines, essentially disabling use-acp:

    apply_properties = {
      -- Use ALSA-Card-Profile devices. They use UCM or the profile
      -- configuration to configure the device and mixer settings.
      -- ["api.alsa.use-acp"] = true,

And now PipeWire and WirePlumber can detect all of the targets.

$ pw-cat -p --list-targets

As Fedora is Redhat sponsored and as PulseAudio is a Redhat product, if you will. I’m curious why you would want to use PipeWire specifically on a Redhat branded distro? That’s kind of like going to McDonalds to eat a Whooper.

Just curious.

That was a decision made by Fedora.

I’d also add that GNOME defaults to Wayland on non-Nvidia systems, and screen sharing-type stuff only works properly on Wayland systems with PipeWire. So it’s sort of non-optional at this point if you’re using Wayland.

Thanks @gclimer! I wasn’t aware they made that decision but it is great to know. Suppose I should a bit more attention to the release notes!!

@illeatmyhat Hi there, went through this myself after Fedora’s 5.15 kernel update borked a lot of things for me. I’m wondering if you also don’t get any audio out of the headphone jack. It doesn’t show up as a separate target when I have a device connected, nor does the Built-In Audio target seem to swicth to anything. Thanks.

My headphone jack works fine.
Having said that, I didn’t upgrade my Fedora installation.
I simply reformatted because I didn’t want to deal with any extra mystery quirks.
Worked out for the better.
I’m running kernel 5.15.6-200.

Definitely a weird mystery quirk. I’m running the same kernel and I have the latest updates for all my audio packages (pulse, alsa, pipewire,wireplumber, etc.). My framework will not switch any output to the headphone jack, nor does it even appear as a device or a sink.

Edit:

I ended up switching from wireplumber back to pipwire-media-session. My headphone jack is now back up and running and it also seemed to fix an overall problem with volume on my system.
