How do I get TV to recognize audio from laptop....

Hooked up MacBook Pro laptop to Planar HDTV via HDMI - DVI cable. Video is great, no audio. Was told laptop is not equipped to send audio this way. Told to use RGA cable from headphone jack on laptop connecting the red and white end of cable to TV, still no audio. How do I get the TV to recognize the laptop's audio?
Thanks!

    I tried that before and tried it again after seeing your post but still no sound. But thanks for your time. The RGA cord has the red and white ends to hook to the TV. Maybe I have those in the wrong places? I have attempted to move them around but still no sound. Does someone know where this end of the RGA cord should go on the TV? Or any other thoughts?

    Thank you!

    You're not going to believe what the problem is. After I did more research on the type of TV we have and how it was all set up I realized I was never going to be able to get audio with what I was doing. I'm technologically illiterate, if you will, so forgive me if I don't use the correct terms..... When we built our house a little over a year ago we had someone install our TV's, stereo, etc and wire it through a system where you can turn speakers on in specific rooms, etc. There's a command tower, if you will, in the basement that holds the satellite, stereo, router, etc. all the equipment to run the TV's, radios, computers and everything is wired from that location to the speakers and TV's. So, long story short, the TV's we have are actually monitors, there are no speakers attached to them. I had everything hooked up properly if we had normal TV's with speakers and not just monitors.

    I'd like to thank you for all your help. It's nice to have people who are willing to take the time to share their knowledge.

    Thanks again!
    Rate? Not sure how...because it didn't help in this circumstance but would have been very helpful if I had a normal TV.

Try the following:

1. Select System Preferences from the Apple Menu.
2. Select the Sound icon.
3. Click the Output tab at the top of the window
4. Highlight the option that is not the Internal Speakers.
5. Make sure the Output Volume is not set low and that the Mute checkbox is unchecked.
6. Close the Sound window. (via Red Radio Button, Top/Left of window).

Try it again and see if you get sound this time.

I hope this helps. Regards,

    The RCA plugs (Red and White) should be put into the TV's Audio IN ports.

    Red should be put in Red and White put in White. Yellow is for Vision ONLY.

    Make sure that the Audio is going to the IN ports on your TV and not the OUT.

    If you have a Stereo with RCA connectors you could also try seeing if you get sound via the stereo. (This may assist in narrowing down your problem.)

    Please rate. Regards,

    I am glad you found the solution to your problem.

    Whilst I wasn't able to provide you with the exact answer (it is hard to, when all information is not known). I would believe that the suggestion of checking the sound through your stereo (for narrowing down the problem) assisted you in some way.

    I was also able to provide you with the specifics you asked, like where do the ends of the RCA plugs go etc...

    Rating a response is not always about if it was the exact solution, but whether it assisted you to find the solution, or whether it was accurate (without being the solution to your problem).

    I am glad you were successful at finding the solution to your problem. Regards,

Tip

Connect you HDTV to your Mac.


One of the first things you may notice about your new big-screen HDTV is that it has more connections for video than your old TV ever dreamed about. It probably has two or three HDMI connections, maybe a DVI connector, a VGA connector, and at least one component video connection. And those are just the connections most commonly used for high definition.
It’s shame to let all those connections go to waste. Your Mac just happens to be sitting nearby; why not hook it up to your new HDTV? It's actually a pretty easy task. A few lucky souls won't even need an adapter; for the rest of us, at least one adapter will be necessary.
Pick the Right HDTV Port For best quality, your HDTV's HDMI or DVI ports are the preferred connection method. Both are capable of the same digital quality. The only practical differences are the style of the connector and the fact that HDMI supports video and audio in a single connection. If it has one, another option is to use your HDTV’s VGA port. The VGA connection isn't as good as the HDMI or DVI method, but as long as your TV supports full resolution via the VGA port, you'll be hard pressed to notice the difference. Mac Pro, MacBook Pro, Mac Mini Mac Pros, MacBook Pros, and Mac Minis have standard DVI connectors. Mac Minis and MacBook Pros have a single DVI port; Mac Pros have at least two DVI ports. If your HDTV has a free DVI port, then all you need is a standard DVD cable; no adapter is necessary. But in all likelihood, you'll need to connect your Mac to your HDTV using either an HDMI or VGA connection; both options require an adapter. If you choose VGA, you can use the adapter that came with your Mac. If you choose HDMI, you'll need a simple adapter, which is available from multiple sources. The adapter may be a cable with a DVI connector on one end and an HDMI connector on the other, or it may be a small adapter that has both types of connectors, but no cable. Either type will work fine. iMac, MacBook iMacs and MacBooks have a mini DVI connector for hooking up external monitors or TVs. You'll need at least one adapter, maybe even two. At a minimum, you'll need a mini DVI-to-DVI adapter. You may also need a DVI-to-HDMI or DVI-to-VGA adapter, depending on which port on the HDTV you choose for the connection. Make the Connection Once you determine which, if any, adapters you need, and have the necessary cable to reach from your Mac to the HDTV, turn off both the HDTV and the Mac. Connect the cable between the Mac and the HDTV. Turn the HDTV back on first. It doesn't need to be set to the connection the Mac is on, but it must be powered up first, so that when it boots, your Mac can recognize the TV and the resolution it needs. Once the HDTV is powered up, turn on the Mac. Your Mac should recognize the format and resolution of the TV, and automatically select the native resolution of the TV for running the video. In a few seconds, you should see the Mac desktop on the HDTV. Over or Underscan You may notice that the Mac's desktop appears to be slightly larger than the HDTV's screen (its edges are cut off); this is called overscan. Or, you may notice that the desktop doesn't occupy all of the HDTV's screen real estate (there are dark areas around the edges); this is called underscan. You can usually correct either issue by making adjustments on the HDTV. Check the HDTV's manual for information on making scan-related adjustments. They may be called overscan, underscan, dot-by-dot, or pixel-by-pixel. If your HDTV has a dot-by-dot or pixel-by-pixel capability, give this a try; it should eliminate any over or underscan issues. Some HDTVs only offer these special scan controls on specific inputs, so be sure to connect to the corresponding input on your HDTV. Time to Watch a Movie Once you have your Mac and HDTV working together, it's time to kick back and watch a video from your Mac. Be sure to check out the QuickTime HD trailers for a sense of what HD and your Mac is capable of. Enjoy!

What cable do I need to connect latitude D600 to a hdtv ?


The first step is to inspect both your laptop and TV and identify the connections, easily located on the back of either component. There are five basic types of jacks, or ports involved:
*Composite/phono plug (RCA)
*S-Video
*Video graphics array (VGA)
*Digital video interface (DVI)
*High-definition multimedia interface (HDMI)
*An RCA connector, sometimes called a phono connector, is used for analog audio and video components. Three round, colored sockets are standard — left audio is white, right audio is red, and composite video is yellow. These are standard jacks on older TV’s and laptops. A three-prong cable, readily available at any computer or electronics, is the easiest way to make an RCA laptop to TV connection.
*S-Video, or Super-Video, a more advanced analog video connector, uses a four-prong round plug, like those used in TV cable installations. Separate audio cables are the same as for the RCA connector, left audio/white, and right audio/red. S-Video is commonly found on older TV sets and some laptops.
With S-Video on both TV and laptop, connecting a laptop to a TV is a simple matter of a single S-Video cable. If your laptop has a great sound system, you won’t need audio cables, but for better quality you’ll also want audio cables.
RCA to S-Video cable, a special laptop to TV cable, is available when you have RCA jacks on one device and an S-Video port on the other.
*A VGA connector and cable are used to carry analog video signals plus display and graphics data. The VGA is a 15-pin connector commonly found on laptops and other devices. With this port you need a PC-to-TV Convertor to connect laptop to TV. You simply plug the VGA cable from the source into the convertor, and use an S-Video or RCA cable out to the TV. The converter is USB powered, so there’s no external power adapter to carry around, making this laptop to TV connection entirely portable.
*A DVI port is rectangular with 24 pins arranged in three horizontal rows of eight pins for digital video; separate RCA analog audio cables fit into white and red plugs. DVI ports are found on Macintosh laptops; sometimes they are smaller than normal DVI ports and require an adapter, which usually comes with the laptop.
*The HDMI port, one-half the size of the DVI port, is also rectangular with 19 pins. It provides digital audio in addition to digital video, despite it’s smaller size, for a complete TV to laptop connection. These ports are found on new HDTVs, and sometimes there are two or more. TVs with HDMI ports are the only ones that do not require additional audio cables.
TV’s with a single digital port labeled HDMI/DVI require only one cable when the source is another HDMI component. But when source is a DVI laptop, you need a DVI-to-HDMI cable for the video and a separate pair of RCA analog stereo cables.
NOTE: Whenever ports do not match, you can by adaptors and/or cables to make any connection.

I have connected my macbook to my tv using mini


Later MacBook (Pro) use a mini-DVI connector that does not pass analog needed for composite or S-video. Was yours ever working? And most DVI connectors do not pass sound as seen by your cabling. You cannot detect display through RCA. You just set it in Sys Prefs :: Displays, try some other settings, although your seem right.

Macbook Pro DVI---> HDMI + Digital Optical Out = Problem w/ Sound


On the Sony The HDMI takes "priority" over all others, that's why you loose audio. If you run your DVI/HDMI to the TV and optical to the soundbar that would fix your issue. If your TV does not have Multiple HDMI inputs, you can get a DVI/Component adapter for your MBP then run it to the TV, or, If you have to have HDMI just to have HDMI, you can get a 2:1 HDMI switch and still have optical to your soundbar. Make sense? If youneed more help, just post a comment and I'll help some more.

Yamaha reciever doesnt recognise hdmi from Mac laptop


Max does recognize receiver over HDMI-CEC.
The problem is that DVI output is for video only. Macbook won't (and can't) output audio via DVI. So yamaha receives only video signal via the HDMI connector. You can check that by pressing Option button on yamaha remote and choosing Signal Info - you will see info about video, but no audio signal present.
