Not sure if this belongs here or in kernel & hardware. Since I did a pacman -Syu yesterday I've been plagued by a problem with the audio. It works, but at random intervals the system seems to think I've plugged headphones into the front jack, then instantly unplugged them again. This causes GNOME to flash a dialog very briefly, but it's so quick I actually had to record my desktop with OBS Studio for a while and step through individual frames so I could see what it was. Below is what appears with pulseaudio -vv when it happens. I can increase the logging level if necessary. Is there a way to add timestamps? In the meantime, how can I stop the annoying popups until I find a proper fix?
