    What are the audio capabilities with the 1st 4 generations of MacBook Pros with standard full size DVI outputs when using a DVI to HDMI adapter?
    I know that the mini display and thunderbolt ports support full quality 7.1 audio at 24bit 96KHz over HDMI (plug and play right out of the box to a surround receiver). What about the DVI machines? Can you at least get stereo audio thru the DVI port for basic TV/movie watching? Or is audio over HDMI only available starting on the 5th generation MacBook Pros?

    As in 'Period. End of discussion. No.' Any threads I see on the internets of people talking about getting audio to HDMI via DVI are full of it and just making stuff up?

    No Mac supports it and I'm pretty sure it isn't in the DVI specifications.

    The 2010 MacBook Pro can output audio via the Mini-DVI using a Mini-DVI to HDMI adaptor. I believe it was the first MBP that was able to do so.

    EDIT: Actually no, they have Mini Displayport, not mini DVI.

    The 2010 Macbook Pro, like all uni-body Macbooks, has mini-DisplayPort, not mini-DVI.

    Oh, right. My mistake. Haha, I always mix those two up.

    Intell is right. Mini-DVI does not support audio.

    Well, that seems pretty bottom-line-ish. You need a 5th gen MBP or newer to get single HDMI cable plug and play for home theater. Alright then.

    hdmi via dvi works, just no audio out.

    HDMI = video + audio
    DVI = video only

    ----------

    yeah, but 3.5" -> RCA works fine and you get audio
