What causes CoreAudio to crash on macOS Sequoia?

MacOS/Version 15.6.1 (Build 24G90)


When using a MacBook Pro with Speakers & External Headphones in Chrome, CoreAudio crashes when I unplug the External Headphones and it doesn't recover until I kill CoreAudio in Activity Monitor.


This issue isn't limited to one computer; some computers have clean environments with no additional audio software. I noticed this problem, but it seems to be related to the use of special software.

I've been capturing system logs, and I hope it will be useful.
