    You will need to use a 3.5mm jack to RCA (black and red - Left and Right) cable as the MBP will only output audio from the headphone jack. This is probably the cheapest option to get sound from your Mac to your TV. Quality will not be the best as it will be analogue.

  • If your TV has an optical SPDIF audio input, you could use an optical audio cable in addition to the displayport / hdmi lead instead of an analogue audio lead - the MBP supports headphone type connectors and optical audio in the same port.

  • If you want the sound to come out of a TV you will need to use the audio jack in the side of your MBP. The MBP can only output audio from either the audio jack ,or it's USB ports ( the Apple 24" Cinema Display uses USB for it's internal speakers and also to power the USB ports in the back of the display )

  • Two factors here. 1. your mac. 2. your TV.
    There is an Apple KB HT4241 which covers details of the HDMI out, but it is vague with dates.
    It also depends on your TV inputs.

    If using the mini display port to DVI adapter, you can connect to your TV with a DVI - HDMI cable and a 3.5mm optical - SPDIF (toslink) optical audio cable. This will give you digital video and audio.

    Your TV may not have an optical audio input, in which case you need to use an analogue input- however, it may not be possible for your TV to accept an analogue audio input with a digital HDMI input.

    This means using a component video or S-Video adapter along with an analogue 3.5mm - RCA audio cable, to allow your TV to accept both the video and audio signals from the same source inputs on the TV (eg AV3 in etc.)

    The alternative is to use Apple's mini display port to VGA adapter and an analogue video/ audio converter cable. This is not a digital signal though.

    Depending on your TV, you may be able to use a VGA cable (d-sub15 pin) into the TV with a matching RCA analogue input. This would require the mini display port to vga adapter for the VGA cable and the separate 3.5mm - RCA audio cable.
