I have a vizio hdtv and i have hooked up the video with a hdmi cable adapted to the mini display port and that is working fine but i can not send sound through it or idk how to. So i bought a optical toslink to mini toslink cable to send audio form the laptop to the tv but the audio still doesn't work. The laptop says that it automatically recognizes it as a digital output. Yea i really dont know how to fix this can anyone help me out?
