When i just watched a Assassin's Creed 3 Tyranny of King Washington,i discovered there was no sound.
I checked but it wasn't muted so try a lot of solutions but didn't work.
I believe that my AMD HDMI was unplugged but i am using latop,there was no such thing as an AMD HDMI cable.
I am hopeless to post this thread!!I need your help!
I will rep anyone who found the solution.
