I bought a Mini DisplayPort to HDMI adapter (http://www.cables2u.co.uk/mini-displayport-hdmi-socket-p-844.html) and this adapter should allow the transmission of both video and audio. Video works fine but no audio is transmitted when I connect my MacBook Air to a HDTV, and there is not even an option to do so under System Preferences > Sound > Output (Internal Speakers is the only option available). Any suggestions?

MacBook Air 11.6 (1.6 GHz, 4GB), Mac OS X (10.6.4)

    Hi guys,

    here we are having the same problem (NO audio). I bought a Moshi MDP to HDMI adaptor. When I connect it with the TV set, video output is nicely working. To
    get the audio output, I tried to choose, +system preference -> Sound -> Output+, is
    chosen as the HDMI. However, *it is NOT working. Any help?*

    My Macbook PRO is bought on September, 2010 and it is compatible with both
    audio and video with HDMI.

    For a temporary solution, I am using the internal audio output with a different big sound system.

    Just to add with the above post, I would like to convey that I went back to the Apple store where I bought this Moshi MDP to HDMI adopter. There I checked myself
    with their LCD TV set and it wz workng very well with my own laptop and and the adopter with the setting mentioned above.

    I have a LCD TV set, Tatung LCD TV from 2010. And the audio system is not working for this HDMI setting. I am yet to solve the problem.

    I bought my MacBook Pro 13" on Oct 2010, and in the system profiler I can see that the "Audio Built-in" has HDMI in the list. And my macBook Version is 7.1 and am having OSX 10.6.7

    I bought a 3rd Party MDP-HDMI Adapter and am having the same issue (no Audio option) with my new Sony Bravia KDL-40X720.
    My parents also have the same macbook and MDP-HDMI adapter and for them it works video/audio on their Panasonic Plasma TV. I can't physically verify the same with mine as I live some thousands miles away from my parents.

    So, probably I'll try with my Office LCDs tomorrow.

    I have been hunting the internet for solutions but am still clueless.

    Any Suggestion will me appreciated.

    Regards,
    Sapam

    The new MBA's (2010) are not on the list provided by Apple as being capable of audio over MDP - HDMI adapters. Search Apple support for the list.

    So , you mean Apple like to inform his clients that HDMI in Apple could be totally different than any other brand in the world? it is really disappointing us , HDMI has a universal definition , like USB , Like AVI and etc. we can't check every company website to make sure that deifine Orange really sme as other people in the world!!

    Apple has to solve this issue as it's really not accepted by the customers.

    I have a hama adaptor to HDMI to a Samsung HDTV.  I got video through system preferences/displays/arrangement/tick mirrors, and audio through system preferences/sound/output/check (in my case) Samsung HDMI.

    Hi all

    Me too.

    I have a moshi mdv to hdmi adapter on my feb 2011 MBP.

    Video works fine.

    I can get audio to my toshiba display (stereo) but not to my Sharp Equis LCD. (stereo or surround)

    Hmm...

     

    Looks like there is something peculiar in how apple deals with its audio out.

     

    LOOKS LIKE THERE IS SOMETHING PECULIAR AND NON STANDARD IN THE WAY MBP AND OSX.6 DEALS WITH HDMI AUDIO OUT.

     

    I wish to monitor my FCPX editing with surround and am not interested in stringing an extra audi wire from my MBP the Surround amp. (enough wires).

     

    Apple, please Help!!!

     

    BTW DVD player and PVR work correctly on the same port and settings in the Sharp Display.

    So i had the same problem...

     

    Silver Macbook pro 13.3" purchased 2010. I connected Macbook to back Panasonic Plasma using a mini display port cable to hdmi (purchased on ebay for UK £7.50) & no sound.

     

    Then i used another cable i already had to connect the audio output/headphone socket of MacBook Pro to your TV left & right audio inputs (one orange, one white socket). Then adjusted settings on TV to analogue sound instead of digital.

     

    It worked.

     

    Am still bewilded as how to do it using just the mini dp to hdmi cable only. Anyone managed it?

    DisplayPort to HDMI Sound is actually set up by using the MIDI setup utility found in :

     

    Applications > Utilities > Audio MIDI Setup.

     

    If you purchased an iWires cable direct from Apple the instructions are in the printed booklet that comes in the packaging. Most people don't read this as it's normally the case that when you plug a cable in to anything it just works (VCR, TiVo, Xbox, video camera etc). In this instance Apple are failing to live up to their catch-phrase as final setup is NOT intuitive; "it just DOESN'T work".

     

    The booklet instructions basically say do the following,

     

    Video

     

    System Preferences > Displays. There are 3 tabs in the window; Displays, Arrangement and Color. Be sure you are on the Displays tab. Bottom left of the window tick "Show displays in menu bar" and then bottom right click "Detect Displays".

     

    Now click on the tab named Arrangement. Bottom left of the window tick "Mirror Displays".

     

    You should now only see 2 tabs, Display and Color. Be sure you are on the Displays tab. Select the desired resolution for your TV (probably 1080i). leave all other settings at their default values.

     

    Sound

     

    System Preferences > Sound. There are 3 tabs in the window; Sound Effects, Output and Input. Be sure you are on the Sound Effects tab. Middle of the window select your TV where it says "Play sound effects through:".

     

    Select the middle tab named Output.

     

    Select your TV from the drop-down list next to HDMI, below where it says "Select a device for sound output".

     

    Using either Finder or Launchpad go to Applications > Utilities > Audio MIDI Setup.

     

    On the left-hand side of the window you should now see HDMI. In the middle of the window, on the Output tab, where it says "Source:" select your TV from the drop-down list.

     

    This last action below is NOT described in the iWires notes but was required in my case, it may also be required in yours. If you CANNOT see a speaker icon next to HDMI in the list on the left, do the following:

     

    Bottom left of the window select the wheel icon with the down-pointing triangle. Make sure that sound output is selected and that you can now see a speaker icon next to HDMI in the list of devices.

     

    If you still cannot hear sound, log out of your account and then log back in.

     

    You will now have sound coming out of your TV from your computer

     

    You may have to do some or all of the above to get sound out of your TV from your computer using the DisplayPort to HDMI cable. On my Aug 2011 MacbookPro I had to do ALL of the above.  If you take your laptop to a different TV you will have to do it all again so be warned.

     

    Hope this helps.
