[QUOTE="bobtomay, post: 1110212, member: 24160"] Check page 34 of the manual - Input Labels. Change the label to something else, particularly if you have selected PC. That selection may be what causes the TV to know you want to use the analog audio input instead of HDMI. Thinking I might try the Game selection. Reboot if that doesn't cause it to auto appear in Sound preferences. Which adapter did you get? I am starting to see a very few machines that just have not been able to get the audio via the mdp that should be able to, and in my mind, not due to user error. At this point I am not sure if it is multiple bad adapters, a hardware issue on the Mac or an issue with the individual TV. I have had only a couple reports back so far that the audio works fine on one TV, but not another. Thus, my suspicion is that it has something to do with the EDID being passed to the computer from the TV, and not something that can be solved short of using a separate audio cable. [/QUOTE]
