Hey Dell.  I have the same monitor and I'm trying to get sound out of either port but can not. Today I hooked up my Nintendo switch to the monitor and only Nintendo no pc. Turned it all on and no sound. I'm using a Sony 2.1 speakers for my pc in the bottom port and side port neither worked. I also tried 3 sets of headsets still no sound. So questions are how do I get sound out of this thing with do I need a pc as a third party for drivers?
