Connected to the output jack of the monitor I have the sound when the driver side everything works, actually over the DisplayPort or HDMI connector.
If that is not possible or not desired, you can plug the course elsewhere plug, but then embarrassed a cable longer.
What I like less and which also leads to the deduction of points is the sound quality. Since I had really expected a little more. There really is a lack of bass and ultimately to volume when fully raised level on the input. Too bad!
