XBox Audio Problems

Check your audio output setting of tv,
nd enable aux out on.

Connect the coaxial "Cable In" cable to the "Cable In" port on the back of your TV cable receiver box. Make sure your receiver box is not plugged in yet. 2 Take the TV audio/visual cable, and connect the red, blue and green ends to the corresponding color "Cable Out" ports on the back of your cable receiver.3 Take the other ends and plug them in to the red, blue and green ports under "V1" on the back of your TV.4 Take the audio cord with the red and white ends, and connect them to the corresponding color ports of "Audio Out" on the back of your cable receiver; then, connect the other ends to the corresponding color "Audio In" ports on the back of your TV.5 Turn on the power of your TV cable receiver box first. Allow it to run through the boot sequence. When you see the time appear on the front of the cable box, you may turn on the television and check your signal.

Every xbox comes with the HD av cords. However they are not only the standard red, white, and yellow. But they also come with green, blue, and red av cords. These are the HD cords.Your HD tv should have green, blue, and red outlets on the back of the tv. It also has a another red and white outlet under it. So you have to take the HD cords and plug them into the appropriate outlets and then take the red and white cords from the other set of avs and plug them in right under those cords so you will have sound when you turn your xbox on. On my tv the red and white outlet is right under the HD outlet. But your tv may be different. And make sure that the "box" on the cord that reads either TV or HDTV is flicked toward HDTV.

Are you absolutely sure you have it wired up right? Are the Cable RIGHT wires color to color, is the "Correct Input" selected? Remember you do NOT use "Channels" but an AV, AUX, or External.input. Most DVD etc, use AV, IE: Yellow, (Video), Red, (Audio), White (Audio) for the OUT connections. These go color to color at TV end. And uses 3 Cables. The "Other" type of Output/Input is Component Video. This is ALL Video, Red, Blue, Green, these go color to color as well. BUT you MUST also send the Sound, Via the AV, IE: The Red & White, AV, Audio IN/OUT connections, So you in this case would have 5 cables/connections in all.

try yellow cable into the green y input.

The problem is that av output is going into component in
If the green port doesn't work I read on another forum that
you may be able to use a dvd recorder unit to take the av in and then it can re transmit the video to an output as component out on some dvd recorders.

There is a switch on the cable where it plugs into the XBOX that says HDTV/TV please make sure that it is set to HDTV when using component connectors.

It depends on what kind of inputs your TV has; here are a few of the most common, all of which your DVD player supports (best quality first):

1) COMPONENT VIDEO (Red, Green, Blue)
If your TV has three inputs for video colored red, green, and blue, this is your best bet for quality video from your DVD player. You may need to buy a component video cable from the store (somewhat pricey, but great quality) which consists of three cables (again, red, green, and blue) stuck together. Just plug the red/green/blue cables into their correspondingly-colored ports on both the DVD player and the TV.
That covers your video. To set up audio, you just need some regular red/white RCA cables. On the DVD player, plug the red/white cables into the correspondingly-colored audio out jacks NEAREST to the red/green/blue cable you used earlier for video, then plug the other end into the audio in red/white jacks on the TV.

2) COMPOSITE VIDEO (Yellow)
If your TV has a yellow input for video, just use a regular yellow RCA cable. Plug it into the yellow video-out jack on the DVD player, then plug the other end into the yellow video-in jack on the TV.
To set up audio, you just need some regular red/white RCA cables. On the DVD player, plug the red/white cables into the correspondingly-colored audio out jacks NEAREST to the yellow cable you used earlier for video, then plug the other end into the audio in red/white jacks on the TV.

3) COAXIAL JACK (Antenna port)
If your TV only has a coaxial jack that you currently plug your antenna or cable line into, you'll need to buy an RF modulater and a short length of coaxial cable (you can find these anwhere: Walmart, Radio Shack, etc).
Plug the RF modulater into an electrical outlet, then plug your antenna/cable line into the "antenna in" jack on the RF modulater. Take the coaxial cable that you just bought and plug it into the "antenna out" jack on the RF modulater, then plug the other end into the antenna/cable jack on the TV. The RF modulater should have a switch on it somewhere that sets either the number 3 or 4; depending on which number you pick, that's the channel that your TV has to be switched to to view the DVD player.
Now you're all set to connect to your DVD player. Just follow the instructions in section (2), only now you're going to plug your cables in the RF modulater instead of the TV.
(I hope this wasn't too confusing; it really is a lot simpler in practice than it is in explanation...)

Had the same problem with mine. Took off HDMI cable and used the HD cable (Red Blue and Green) for video and standard (red and white) cable for audio.
Problem gone

Hi,
I think DVD player is hooked with TV via component video input.

Check component video connections and make sure each color wire connect in same correspondence color in both units, TV and DVD Player.

Red to red, green to green and blue to blue.

Very often on HDTVs there may be more than one YPbPr connection... That is the Red Green and Blue. Under each one, or next to, or above, there should be separate red and white audio hookups for each set of YPbPr hookups.

Make sure they are hooked into the corresponding plugs.

Hope that helps.
