Playback devices gone and no sound suddenly after updating yesterday (Fedora 36)

Distro: Fedora 36

So, normally audio works just fine (I have a Sound Blaster Z sound card) and I can select the output. However, all of a sudden today it's completely broken. At first I saw a muted microphone icon in the system tray and noticed that only the HDMI audio output was available. I tried reinstalling pipewire, pipewire-pulseaudio, wireplumber, alsa-firmware, etc, and now the icon is entirely gone. I can't even select my sound card in alsamixer, it's just... gone (the device does show up in lspci though).

I tried following this article, but nothing changed: https://www.ericsbinaryworld.com/202...for-fedora-36/

When I check the status of the wireplumber status however, I do see this:

Code:

Tried booting into an older kernel, my sound card is showing up in alsamixer now, but the issues with pipewire persist, and I'm still unable to get sound working.

EDIT: sound does work now, though I can't adjust the volume with my keyboard keys, nor does the audio icon show up (audio setting is also missing from system settings).

It is quite possible you may get a better answer if you were to ask the question at https://ask.fedoraproject.org since that forum is specialized for fedora and has a lot of users with the Fedora 36 OS and they may be able to point you to the cause and a quick fix.
