I'm glad your issue for now is resolved.
It's unfortunate it appears to be related to the November update. As you said, 'Hopefully, Microsoft will fix the issue '.
This particular issue has arisen in previous years, so it seems to me that there may be some companies not working too well with Microsoft to keep on top of System updates. Usually when issues arise, then rolling back a driver update, or installing the latest driver will resolve things - alas not in your case.
Fingers crossed the next Windows 10 update will work out for you!
ps: If this issue arises again, something else you might consider trying is to update the audio driver, but rather than grab realtek, instead choose to pick one yourself, and see whether or not Microsoft's generic HD Audio driver works for you.
I've had to commit to that myself on one computer owing to the fact IDT audio drivers no longer work at all in Windows 10 - they used to.
