It does not work to capture or record the internal audio in Obs Studio or Simplescreenrecorder.
After recently upgrading, when I try to record or capture audio using OBS Studio (in a Wayland session) or using SimpleScreenRecorder (in an Xorg session) the internal audio (or output audio) is not detected, it only captures the microphone input.
I am using Fedora 35. I am not sure what configuration files or what dependencies I should check to solve the problem, I think it is a bug with Fedora since two days ago it was working fine, additionally I have tried in other Linux distributions and they do not have the same bug.
I ran all the commands to debug and they were successful. When I ran systemctl --user status wireplumber, I got an error/failure

It seems that the problem with Pipewire was already solved and merged into the main branch by your contributors 12 hours ago. Thank you very much for guiding me and telling me about Pipewire and Wireplumber.
