I've found a thing.

My error was this one:

ERROR: invalid json grep: warning: stray \ before #
[{"id":1, "device":"alsa_output.usb-Logitech_Logitech_G930_Headset-00.analog-stereo", "icon":"google-chrome", "name":"Google Chrome"}]
invalid json from server
App sinks returned an error, audio backend probably crashed. Server will be closed.
Could not join subscribe_thread (maybe there is none)
closing client handler threads...
closing socket
sending exit signal to listener thread, it should exit within 2 seconds...

I suspected my headset to be the cause so I unplugged it, but no, I got this error:

RROR: invalid json grep: warning: stray \ before #

So I supposed next that it would be for chrome (chromium actually) which was using my input/output. So I closed chrome and bingo, it worked.

I tried for some more tests and closing the tab that was using input/output was enough. 🎉

Hum it appears that I have that error without any dump this time :/ (on startup, nothing is running)

I'm getting this too. Running Arch and Pipewire, FWIW.

I also have this issue, remedied by closing my Firefox tab that had audio output. Pulsemeeter just closes when playing any browser audio.
