output sound just stopped win 11

Hello,

Recent upgrade to win 11 from win 10, from a certified MS reseller.  All was fine for about 2 months.......THEN... one day my old guy analog mini jack plug in speakers just stop working.   

Have verified the following: Driver OK, Win Update OK, mini jack cord OK, speakers verified with other source-OK

I do get a buzzing in the speakers when I first introduce the jack to the inlet, but when fully inserted, silence.

Also no sound in PC speaker and no sound to plug in head phones.  Neither youtube, nor zoom has sound output.  Brower window does not have option for any sound.  Speaker icon is "x"'d out.  

PC Settings has no option for adding wired device.  No pop up to acknowledge new plugged in device, like win 10 had.
