A:AnswerTo connect 3.5 mm analog headphones, you will need either a digital to analog converter with SPDIF cable or 3.5mm Stereo Female to RCA Male 8" Cable.
The SPDIF cable with Analog converter can go into the side panel with digital sound out put.
The other cable can also go on the side panel but will give analog output.

A:AnswerYes. If your pc has HDMI output. If you have DP or DVI output to HDMI that will also work but the sound will come from the speakers of your PC or Laptop.
