Well this got me thinking... I took my phone apart and checked where the mic port is. There is a small rubber piece inserted into the back housing of the phone that covers the mic port on the main board. There is a small plastic rectangle piece that is glued to the top of the rubber and it looked dislodged. I repositioned it and also took a pin and made sure the small hole in the rubber was clear. I put it all back together and gave it another try. Viola!!! My sound issues are gone!! "Everyone hears me crystal clear now!!" I am so happy!! Thanks jaleesag88 and thanks seidoseido for helping me solve this problem. I am glad that I found a solution with your help. I will test a few more days, but I am pretty sure I will be keeping the case after all!!
