Sound isn’t working after upgrade to Fedora Linux 35.
There are two possible known causes for this, with different solutions.
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”.
In other cases, WirePlumber may be running, but you still don’t have sound. In that case, see below.
Situation 1: Wireplumber not running
systemctl --user status wireplumber.service — run as regular user, not root — says “disabled” and “inactive”, this is likely your problem. The upgrade process should have taken care of this, and we expect this to be true for almost everyone.
If this did not happen properly when your system was upgraded, 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
Situation 2: Pulseaudio still in use
There is another potential cause of sound not working after upgrade to Fedora 35. If
wireplumber.service is enabled and running, but you still do not have sound, run the following command (as regular user, not as root):
systemctl --user status session.slice
if it shows all three of
wireplumber.service running, like this:
├─pipewire.service │ └─4071 /usr/bin/pipewire ├─pulseaudio.service │ ├─12324 /usr/bin/pulseaudio --daemonize=no --log-target=journal │ └─12391 /usr/libexec/pulse/gsettings-helper └─wireplumber.service └─4072 /usr/bin/wireplumber
then this may be the problem: it appears this configuration does not work, either some or all of the time. This case may result if you manually switched back to pulseaudio from wireplumber in Fedora 34, or possibly may occur on systems which have been upgraded constantly from an older release.
Try switching fully to pipewire, with this command:
sudo dnf swap --allowerasing pulseaudio pipewire-pulseaudio
If that still does not work, as a last resort, you may try to switch back to
pulseaudio, but remove

None yet, other than the workarounds.
