Hello, I have the exact same issue, the problem isn’t with Output but the Microphone (input).
The microphone is detected as an input just fine, but it just doesn’t pick anything up.
I’ve read through and tried the steps in both links in the replies here but they did not work.
I also tried these commands to swap back to pulseaudio along with reboots but this also did not work.
The steps in the arch wiki aren’t helpful as I don’t have /etc/pipewire
(cannot post link because new user)
Yes, the service is running ok and I have ok Output.
