tinkers with pulseaudio
“Why does my audio not work?”
tinkers more
“Okay I think it kinda works now?”
it breaks again
“fml”

I found the docs for pulseaudio and particularly for pipewire to be rather hard to use, personally. RTFM works if the manual is readable, but in these cases, the learning curve was very steep for me (and I still don’t know that I properly understood what’s going on, but it’s working, so I’ve stopped tinkering for now).
