I know there a lot of threads on this topic. I've read many (most?) of them. I've banged my forehead against the desk. I have cursed. Then I thought I would pose the question again for any patient, helpful readers. I have a 2007 15" macbook. I have a new Samsung HDTV. I am trying to hook the two together. Here's what I have connected (using cables bought at the Apple store the other day): HDMI DVI cable from computer to HDMI DVI port on the TV. Audio cord (has two plugs for the TV -- one red, one white) to the audio ports associated with the HDMI DVI video port on the TV. Great picture. No sound. I read several posts indicating I may need to make some adjustment in the sound settings in my computer. There only appears to be one setting for outputs in System Preferences: Choose a device for sound output; Name: Internal speakers; Type: Built-in Output. I have looked for some way to adjust the audio settings on the TV, but HDMI DVI seems to be my only option. Am I just screwed? do I give up before my head explodes? thanks to any who can stand to consider this question yet again.
