Hi! I recently bought an used Surface Pro 2. When I use headphones the sound is so badly distorted that I can´t use it. The build in speakers are ok. It is like some sounds almost disappears, and other sounds like a heavily compressed mp3. I have tried the Realtek HD drivers, but no difference. I am not sure if this problem was there when I got it or it happened with an update (something was updated 14/5 I think). I had another Surface Pro 2 before this, and that did not have any problem. Anyone had a similar problem?
