Dell has posted THREE different versions of the Realtek HD Audio drivers all dated May 31, 2017.
*** Dell??? Have you NEVER HEARD OF QUALITY CONTROL CHECKS PRIOR TO POSTING NEW DRIVERS?!?!? I've now spent an offensive amount of time downloading and installing these *** drivers multiple times. You folks seriously need to step up your game! (You staffers that read/speak English as a second language may need to look up that phrase.)
And to rub salt into the wound, checking Windows 10 Update History shows all three versions to be the same F'ing release numbers!!!! C'mon Dell... really?!?!?!
