Why is the audio playback delayed or sounds in slow motion? S6 edge+

[AC Question]

Recently got the s6 edge+ and a few days later all the sounds even the touch sounds playback at a slow rate, like in slow motion. I was installing implosion, a game, before it happened. Uninstalled it now. I haven't dropped this phone yet or even got it wet. When I tested a headset everything played fine but once I remove it, it goes back to the slowed down version
