I hooked up my mac pro to my olevia hd tv via a mini display to hdmi cable. However, it only displays picture, but no sound. when I go into Sound and I select digital out it says "The selected device has no out put controls" and there is no sound and when I select line out it does nothing as well. When I have the same set up in win 7 via bootcamp it instantly works no problems so it cant be my tv or the cable. Its a software issue. What do I do? I already tried rebooting.
