    I have a 2013 11" MacBook Air 10.8.5. Using the Mini Display Port connected to my TV via an HDMI adaptor there is video but No Audio. System Preferences->Sound->Output does not show any TV's.

    Is there a solution? Thanks

    (I also have a late 2008 MacBook Pro that has this same problem but it's my understanding audio is not supported on the earlier models, but it should be on the 2013 Air)

    HDCP... If you have a modern TV, this is often a failure of the HDCP protocol. Try plugging and replugging the cable....

    It depends on the DVI version but most do not support audio signal.

    Hi Gav2k. Sorry, not sure what you mean or which laptop your referring to.

    The one for the MacBook Pro supposedly works by combing the video signal of the Mini Port with the audio of the USB into an HDMI cable.

    For the macbook air listed in the OP, you are going to need the first adapter you have listed. As stated above, the reason you can't get sound now is because the DVI adapter doesn't support it.

    I used a mini-display port to DVI and then DVI to hdmi for the longest time with my 2011 macbook air. I just had to turn the speakers all the way up to be able to hear it. The mini-display port to hdmi was well worth cost, once I finally got it.

    Sorry if I confused you. The mini display port was retasked and renamed a couple of years ago. It's now known as a thunderbolt port.

    I bought a $5 mDP to HDMI adapter off Amazon. Works fine with my 2013 MBA. Just make sure the reviews state that it carries audio as well.
