    I have a macbook pro and use a mini dvi to hdmi cable to plug into my tv using hdmi.

    i can get the display working fine but i cant get the computer to detect the speakers of the TV through the hdmi cable.

    however using someone else's macbook pro, the speakers are detected.

    any ideas how i can use the TV speakers through the hdmi cable on my macbook pro? im doing the exact same things on both computers but it just wont work on mine.

    the other macbook pro is slightly newer (about a year) but both are updated to the same OS

    all help is much appreciated thank you

    Check

    Settings:

    System Preferences > sound > change output to HDMI or external.

    +1. I also found that it is best to plug in the adapter/cord first, then turn on the TV. Dependng on where the audio is from, that may have to be done before the application starts.

    Mid-2010 MBP was the first MBP to output audio over the mini-DP port.

    if this is true then i dont think mine will do it, when i go to settings>audio>output i dont get the option to switch to the tv.

    is there anyway i can get around this problem using other programs etc?

    EDIT:

    i am trying to avoid using additional cables

    I believe using an HDMI to DVI adapter looses the audio, as DVI does not carry audio.

    The confusion is that you keep calling it a mini-DVI to HDMI adapter, when it is in fact, a mini Display Port to HDMI adapter.

    There is no way around your problem without a very expensive adapter (and still another cable). I would recommend either getting a mini-jack (headphone) to RCA adapter, or if your TV/Receiver support it an optical audio cable.

    I recommend www.monoprice.com

    Most likely, your MacBook Pro is one of the models that does not support audio out of the Mini-DisplayPort jack (you don't have Mini-DVI, as another poster clarified). You'll need to simply run a cable for audio, or get one of the more expensive adaptors that builds in USB audio as well.
