Hello, has anyone of you noticed the sound problem that probably every surface has? I have two surfaces and the problems appears on both. Here is how it comes up: 1. plug in headphones or speakers 2. play a sound/song whatever 3. stop it. Make sure no other sound is present (e.g. the sound of double clicking or a warning sound) 4. after a while a constant "bum bum bum bum" will appear on the headphones/speakers until you play another sound This does not happen with the internal speakers, only when you plug speakers/headphones in. Can anyone confirm that for me? I tested it with this http://www.amazon.com/Beyerdynamic-70-Over-Headphone-Black/dp/B005EEOTFY/ref=sr_1_1?ie=UTF8&qid=1411242424&sr=8-1&keywords=t 70 and this http://www.amazon.com/Logitech-X-530-5-1-Speaker-System/dp/B0002WPSCG/ref=sr_1_5?ie=UTF8&qid=1411242479&sr=8-5&keywords=logitech sound and some inears. I also reinstalled windows. I tried everything but it appears on both surfaces - no matter what I do.
