I hope I am not repeating someone's discovery, but I found how to get the distorted sound straight without waiting 2-3 minutes for the device restart. Simply open a 1080p video in youtube and when it starts playing press the power button so the screen turns off. In a second or 2 you should here the sound dropdown for half a second and then goes up again. This is where my distorted sound goes away. Sometimes I have to try it a few times.

I hope that works for everyone
