Hi. Has anyone faced problems with the voice coming from headphone? Sound including voice works great from the speakers, but the moment I put in my headphones, the voice from the videos /music/ YouTube becomes so slow that I can hardly hear anything. I tried on 3 different headphones and unfortunately the same result. In addition, I observed that if the headphone jack is inserted halfway through, the voice will come out loud and clear but from one side of the headphone (it becomes mono). Hope someone can shed some light on this issue of mine. Thanks!
