Hi, I have an Evo 16 audio interface connected to a PC running an updated Ubuntu 23.04 with low-latency kernel (plain install, with Pipewire enabled and no PulseAudio). I have a mic connected to the interface's AUX7 and I have my headphones plugged to the interface's headphone's output 2.
On pavucontrol, the Evo 16 is enabled as Pro Audio both for input and output. I can see all the input & output channels enabled including AUX7. The Sound settings look good. Mic doesn't show as muted, volume shows as 100% 0dB. And yet, the audio signal from the mic isn't coming through (the interface display shows that there is an active input signal, green/yellow/red). Playback i.e. playing music or videos in the browser works just fine.
What is more interesting, if I open Bitwig (v5.0.3 with Pipewire enabled), channels are recognized and playback works fine, and... I also can hear and record the audio from the mic with the expected sound volume and quality.
I don't understand why the audio input works for Bitwig but not for the system. I don't know where else to look and I don't know how to debug this problem, even less how to fix it. I'm asking for help here after a couple of hours searching for information and trying out things like upgrading Ubuntu, restarting, changing pavucontrol's configuration, etc. I welcome any advice!
