So you have this problem too? then we are two now. Mi problem is this: the right speaker sound like the wings of a bumblebee are being flapped inside the tablet, It is noticeable with sounds that have bass or are very loud in origin. It sounds like a hardware problem to me, but there's still hope it will be corrected with some driver, very small hope though. My solution was to open the volume settings and pan the master volume to the left (correction: just lower you right speaker volume to 0), now I have mono sound but with no distortion, sigh.
