I have an Optiplex 760 that runs windows, and what happened was everything was going fine until I updated my computer to version 1706, and BOOM my sound doesn't work it says it's not plugged in when it is, and it also says when I hover over the sound icon "No speakers or headphones are plugged in." I really need help! I'm getting frustrated about this.
