Got a bit of a weird problem with pulseaudio: Audio using my usb audio interface (Focusrite Scarlett Solo 3rd Gen) works fine, until I open pavucontrol. When pavucontrol is opened, it seems to switch modes, and i get crackling noises in the output audio. Killing and restarting pulseaudio fixes the problem.
What should I do to diagnose that problem further? `diff`-ing the output of `pactl list sinks` shows only the latency has changed.
