I currently have no audio in Fedora 35 afdter an upgrade:

[root@localhost-live Definitive]# wireplumber

Any tips?

Here it shows how to check and re-start Pipewire / Wireplumber etc.

systemctl --user enable --now wireplumber #Please read the wiki article first !

Resolved

In some cases, the new WirePlumber service may not be properly configured to start automatically after an upgrade. WirePlumber is a session manager for PipeWire, the modern audio subsystem we made the default starting with Fedora 34. You can read those links for details, but the short version is “this needs to be running for sound to work”. The upgrade process should take care of this, and we expect this to be true for almost everyone. However, if your system is one of the unfortunate exceptions, run the following command AS YOUR REGULAR USER from a terminal ( not as root or with sudo ), and everything should start working:

systemctl --user enable --now wireplumber
