Posting only to give this problem more traction.
Running an HP Envy laptop, am a Zoom power-user for music instruction.
My on-board microphone will randomly stop working in the middle of Zoom calls. If I change microphones, and reselect the on-board, it kicks it back on.
After countless hours trying windows updates, microphone driver uninstall, reinstall adn update, Zoom software deletion and reinstall, with no fix, I looked to error logs. I'm a newbie to this, didn't know what I was looking for.
After recording the times I noticed the microphone stopping, it was the exact same time that this error message pops up.
Upon reading through this thread, I also have issues with my computer going to sleep, then monitors refusing to turn on (black screen) so that I can log back in.
I have had these problems for months, I believe it's linked to a Windows update.
I have disable MS account sign-in assistant, didn't help.
Haven't tried turning off overclocking, doubt I have it even turned out.
Will be trying to work-around of disabling the log. Hope we get a fix.
