    Make sure that the ports you're connected to on the TV correspond to the video input you're using. Make sure the volume on your computer is turned up. Make sure the mute on your TV isn't on. :p

    dvi and minidisplayport don't output sound. You have to get an audio -> rca cable. If that doesn't work then idk.

    OK, there's no port for a red/white cable connection on the MBP. :eek: What I've done is get a plug for the headphones jack on one end and a RCA plug: yellow (video), red (audio) and white (audio) 3 to 1 on the other end and plug it in to the audio-in on the TV, don't plug in the yellow cable, and you should be good to go...

    Check your sound control panel and make sure the selected OUTPUT isn't "built-in Speakers", or the system is muted.

    The DVI port of a mac wont transmit any audio data, also HD-TVS have HDMI, RCA, COMPONENT, ETC as different inputs, therefore of you transmit image through HDMI, audio has to come through that HDMI also.
    Most HD-TVs have a PC input which also have a mini-jack input, if yours have, just connect your mac to your tv using a DVI -> VGA (HDTVs have VGA instead of DVI) and then connect mini-jack from your laptop to the tv's mini-jack input.
    This is the back panel of my HDTV, sorry for the blur...
    Notice that just below the VGA port there is a mini-jack plug, indicating that those to inputs go together. RCA goes with RCA (maybe you can get a DVI to RCA (e.g. DVI->VGA->RCA) and then you do can connect it to your HDTV RCA input.?
    However if your HDTV does have VGA input thats your best choice, else you can get something like this then using a DVI -> VGA adapter -> this cable and maybe some extension, you could get it to work with RCA input, however I am not sure if it would work since DVI is digital though i believe it will.
    There is also this solution
    However I haven't tried it, and i believe is somewhat expensive, but if you use something like that, you can then use an HDMI cable and thats it.

    Use a DVI-VGA adapter (included with prev. gen MBPs) and a VGA cable for the video-in the TV (probably labeled PC input,) then use a two-ended mini-jack (headphone type) for the audio. That should be on the same input circuit for the TV as the PC-input. I just had to do this last night on a Sony HDTV, and it worked.

    Also, I set up my laptop display prefs to mirror the display, and then just dimmed my MBP's screen all the way down instead of running in clamshell mode (to keep temps down.) As others have said, make sure to turn the volume up on your laptop. Good luck.

    See this thread:

    Solutions are towards the bottom.

    HDMI from a traditional video source (eg cable box) send BOTH audio and video. The MB can only send VIDEO from the hdmi port. The will only recognize AUDIO and VIDEO from HDMI cable, and you cant split it up and do video over hdmi and audio over rca. Swap out your dongle (minidisplay to hdmi) for a minidisplay-vga or to a minidisplay-rca, and then run the audio from the headphone port to the tv with the white/red rca cable.

    Hope this helps.
