So i was going to mute my sound for a sec, and noticed my charcter was moving. Had to try again and he moved. So i had to test all the keys used for media player. Mute button press make character take step, holding it make character run. Using volume wheel ( like a mousewhel ) charcter make stutter moves Trying play/pause, previous and next makes the character run. So not sure what causes this. But I am pretty sure it is the first time i have ever encountered this type of problem.
