Galaxy player 5 no sound
Hate this to be my 1st post but I installed Beats Audio on my rooted GP5 and next then I know all of my videos will have no sound and it just continues to fast forward or speeds up. I can't hear or use Youtube for video and again sound. I tried hard reset, soft reset everything nothing works. I thought it was my external SD card that's not it I put it in another phone and everything works fine. I scanned the hard drive for errors and everything came out fine. What should I do next?
Any help would be appreciated!!
