    It would help to know which one of the 9 different models of MacBook you have. To see which model you have go to the Apple in the upper left corner and select About This Mac, then click on More Info. When System Profiler comes up check the Model Identifier and post it back here.

     

    If you connect the MacBook using a Mini-DVI to HDMI adapter you will probably need to use external speakers or a 3.5mm stereo headphone jack to RCA sound plugs connected to a stereo system for audio if your TV doesn't have separate RCA input plugs or a 3.5mm stereo input plug for audio with the HDMI plug. The Mini-DVI to HDMI doesn't carry audio and there're no audio plugs on most TVs to work with HDMI since it's expecting audio with the HDMI.

    thanks for your reply - the problem turned out to be that I had the wrong cable for my model of the Macbook. The general advice was that the older model (which has a battery that can be removed without using a screwdriver) requires VGA connector (for video) AND separate 3.5mm audio connector (for sound) - whilst the newer model (with battery that requires screwdriver to remove it) just requires the Mac to hdmi connector cable. My model which is about 3 years old looks like the new model, with screws securing batterry but in fact it is the older model variant. So, I went back to the Apple store and swapped the Mac-HDMI cable for the "old style cable & adapter and it works fine.

     

    p.s. Apple store staff really helpful... as, in my experience, they always are!

    This is a problem that I myself am experiencing at this very moment. I have an old Macbook 4,1 (circa 2008) and an HDMI cable but I have been advised that for sound I should attach the macbook to the TV with audio plugs from the headphoen socket. I've done this but it still doesn't work.  Good picture on the TV from the HDMI cable but no sound - and I do have what I think are RCA plugs on my TV - they are the yellow white and red ones are they not?  Do I have to adjust the sound settings on the TV or the Mac?

     

    Many thanks to anyone who might be able to help.

    The yellow, red & white plugs are for Composite input not HDMI. The yellow plug is for video and the red & white plugs for audio. You would need audio plugs that are dedicated to an HDMI input.

    Thank you. But I'm not sure what the HDMI audio input looks like. The HDMI video input is a rectangularish socket, obviously linked to the HDMI video cable.  Also what should the HDMI audio plus look like - is it just one plug?  Thanks again

    There're no audio plugs on most TVs to work with HDMI since it's expecting audio with the HDMI. You have to read your TV's manual to figure out if it has a way to add audio to an HDMI feed.
