Acer a1-830 Tablet Problem

AC Question

Hey guys, i have a acer a1-830 and to be honest, its really awesome. But, the thing that isnt awesome, is that the internal tablet makes noises. Noises lead to: can't record or pick up sound because of the sound. Unfortunately, this is my problem. :( My sound recorder or voice search doesn't pick up any of my voice. Except it picks up the internal scratchy sounds. Its really frustrating cause it used to work the first week i bout it, but it was on and off etc. Please help me I love recording and taking videos (which also doesn't work c: )
