Hello.
Yesterday I updated my system after receiving a conflict warning between pipewire-media-session & wireplumber packages. but after I restarted my computer, I couldn't hear any kind of sound anymore.
my interface looks like this:
https://drive.google.com/file/d/1NyBLe9ULhekFaGLUn3dtAniWnXMTif2K/view?usp=sharing
a "speaker device" should appear next to "headset microphone".
I've already tried changing the settings, but I didn't get any results. If anyone knows how to solve this problem i will be grateful.
