    I am trying to hook my Macbook Pro up to my HDTV. I have the DVI to HDMI cable which I am guessing is what I need to hook up the video portion.

    What do I need for the audio portion?

    Thanks,

    Robert P

    What inputs to you have on your TV and/or receiver? Best is optical.

    You have exactly two choices.

    Your macbook has an 1/8" minijack output, you can use a standard 1/8" to RCA cable and run analog audio to the standard white/red inputs to your TV.

    It also has a neat trick where they pack an optical audio output in there too, but with a weird connector. Go buy an TOSLINK Optical to "Apple optical" (I'm not sure what they call it) and you could run digital audio to your TV.

    I'm assuming your TV has an optical input, it most certainly has the standard RCA plugs.

    That is all the options :)

    You are not getting audio because DVI does not export sound, so when it gets converted to HDMI (which does carry sound), it doesn't matter as there is no sound to convert.

    Like mentioned above, you can get a 1/8 to RCA cable (Cheap),
    or one of these http://www.mycablemart.com/store/cart.php?m=product_detail&p=374 along with an optical cable to plug in.

    Are you saying that the 1/8 mini jack has an optical jack inside of it?????. If so that is way cool and something that I did not know. Will this allow you to have 5.1 surround sound?

    Yes, and Yes!

    And yes, it is very cool :) It just needs a special cable like THIS one:

    It's called a 'mini toslink' but Apple is the only company I know that uses it.

    Yes, it's a dual-function analog/optical digital port. It will deliver whatever Dolby Digital your media has encoded in it - 1.0 to 7.1 or whatever. Your receiver needs to be able to decode DD, though.

    Yea all macs have optical out (mac pro is toslink though), you just change it in audio settings to tell it to output audio, and also if I remember right a little led is outside to tell you it is using optical or something along those lines, I cant remember.

    Crazy huh? :) I was a bit shocked myself as I've never heard of any other company doing something like that.

    It's pretty nifty.
