Q: No sound when I connect iMac to HDTV

I just connected my iMac to HDTV with mini-display/thunderbolt adapter to watch movies.

 

I get the image displayed on TV by dragging the window in the arrangement position but I am not able to gat the sund output from TV.

 

I selected my Samsung TV in the sound systems preferences but it's written that the selected device has no output controls

iPod touch, iOS 4.3.3 (8J2)

    HAve you seen this About Mini DisplayPort to HDMI adapters

     

    Some Mac's support audio over mini display port some don't.  Check to see if your mac does.

     

    In additon the adapter must conform to the VESA DisplayPort Dual-Mode Standard

    This is a screenshot of my Sound menu within System Preferences (I have my MacBook connected to a TV. Video is carried via a Mini DisplayPort-to-HDMI adaptor. Audio is carried over a 3.5mm stereo audio cable.)

     

    1. Up top, select "Line In" option (or something to that effect).
    2. Then at the bottom, that "Output volume" slider is what controls the volume level being "outputted" to the TV.

     

    Cheers!

    I had the same issue today, 23 Jan 2013.  In case anyone else sees this post like I did looking for an answer and has same issue here is worked for me.  Under SYSTEM PREFERENCES> SOUND menu select sound effects.  Play a sound effect on your computer.  You should see the option to select your TV. Click it.  Play a sound effect again and it should now be heard on you TV speakers.  Go back to the window of the video you want to play the video... sound should now play through TV speakers.
