Speaker and headphones are not recognized

Hello,

after installing wireplumber on Arch Linux and added the line exec wireplumber at the end of /etc/pipewire/pipewire.conf and restarted pipewire.service I get the following warning click here

and there is no audio (GNOME's audio applet doesn't even show up). In the Sound section of GNOME Settings I have a bunch of output devices, but no one seems to work, meanwhile only and input device is recognized (in reality my Headphones has a microphone which pipewire-media-session recognizes correctly).

I think it might be due to wireplumber because with pipewire-media-session the sound works, even though I can't switch between my laptop Speakers and Headphones.

pipewire: 0.3.17 wireplumber: 0.3.0
