Here's my issue: I just bought a DVI to HDMI cable to use with my Mini-DVI to DVI adapter and my Macbook. I successfully connected to my 40" Samsung LCD TV. AFAIK, the DVI port doesn't send audio, even though HDMI can receive it. So the next step I want to take is to also transmit the audio to the TV. I have a cable that will go from the headphone jack on the Macbook to the composite inputs on the TV, but on the TV's source menu, the HDMI port (HDMI 3) is seperate from the audio inputs (Video 3). What can I do? I know I can use a regular video cable, but that will be worse quality on the TV, no?
