Welcome to ask
What about wireplumber? Is this ok too?
systemctl --user status wireplumber*
Wireplumber is new on F35 > Releases/35/ChangeSet - Fedora Project Wiki see point 2.17
If everything is fine in with wireplumber, please check on the laptop if mute and un-mute the output helps. This is a problem i noticed the last few days.
I recognized my problem also on zoom. I connected to a meeting and there was no sound. But in reality the volume was just very low.
