This started yesterday and I have confirmed that no updates have been installed since Saturday. For the first half of this week, my audio has been working fine and I can capture desktop audio as needed, but yesterday I was no longer able to capture desktop audio. The vu-meter in pavucontrol remains at 0 for all outputs despite the fact that I can clearly hear desktop audio.
What I've tried:
1) restart (full power off + unplug and turn back on in case it's a hardware issue)
2) plugging in a USB audio interface (vu-meter still stays at 0 and cannot capture output)
3) using JACK (this works)
4) trying to capture from ALSA instead of pulseaudio (hw:1,0 device or resource busy)
I'm not sure what to make of this. It's working, but it's not "working" in the sense that I can capture desktop audio through OBS, audacity, ffmpeg, or any other capture script that I could use 2 days ago (and I can confirm that this started 2 days ago because I recorded a screen capture which worked fine).

If I had to guess, I would think that applications are somehow bypassing pulse and writing straight to hw:1,0 via ALSA, but why it started doing that now is confusing.
Any idea how I fix this?
