Dell XPS 8930 W64/Win 1809
Headphones don't work when plugged into front or back audio jack. Audio is Reatek HD. Have twice uninstalled/reinstalled Realtek driver. Only way headphones work is to plug them in before you boot...and leave them. If you pull the earphones plug out and reinsert, the jack does not work again. The sound controller is something called WAVE audio. Now when I want to use earphones, I have to plug them in and restart the computer.
