    I have a 3.2 Ghz Intel Core i3 Imac and I bought a Mini Displayport to HDMI Adapter to connect my computer to my Panasonic Plasma TV. My desktop shows on my TV but sound only comes from the computer, not the TV.

    Does anyone know what I have to do to get the sound to come from the TV?

    if its the 2010 imac model, the mini display port does not carry sound support. you need to run an audio cable from the audio out on the imac to the audio in on the tv.

    Not true, it was the 2009 iMacs and MBPs which don't support audio over MDP.

    i saw this on the apple website and assumed it meant no audio bc it says no hdmi.


    Mini DisplayPort output with support for DVI, VGA, and dual-link DVI (adapters sold separately); 27-inch models also support input from external DisplayPort sources (adapters sold separately)

    EDIT: and this shows that it carries audio http://www.everymac.com/systems/app...e-i3-3.2-27-inch-aluminum-mid-2010-specs.html

    my bad. in that case do you have to select sound under system preferences (i dont know and just wondering bc i dont have an audio enabled mdp). if not that then try a different adaptor or hdmi cable. ill try to think of more things

    Thanks guys.

    I called Apple and they said that if the adapter didn't work then I would have to buy another cable that supported audio. So, it looks like I'll have to bring back the adapter and buy the cable..

    Just an update. I have audio from my Imac to my HDTV now. I picked up a Belkin mini display port to HDMI connector at an Apple store and it worked fine.

    You have to make sure to go into your sound settings and change the sound setting from your internal speakers to your TV.
