AV problem with audio/video

[quote user="PROF4NE"]I wanted to stick with the orig. Analog audio connecter.[/quote]Mind clarifying this?



Are you using the thin AV breakout that comes with the HDMI AV kit, or did you somehow fit a standard AV port cable in alongside the HDMI cable?



The AV port pins determine how audio and video are handled. In the case of the thin AV breakout, it's pined to indicate that video is via HDMI. Using an AV port cable that has video out on it will not work properly.

You need the thin AV audio adapter that comes with the original HDMI AV kit. You can usually find used adapters on eBay or perhaps even at GameStop. The adapter provides left/right audio as well as optical audio while enabling the HDMI port for video.



Devices plugged into the AV port determine what video output the 360 uses. Wedging a regular AV cable with video into the AV port, alongside an HDMi cable, confuses the 360, disabling HDCP. This may be causing the monitor sync issue you're experiencing.

There is a problem with many third party audio adapters in that they're wired to identify themselves as a full AV cable to the Xbox 360. The original audio adapter which is no longer in production, was wired to have its own unique identity.

So in a nutshell, the Xbox 360 thinks it's supposed to be sending composite video over the AV output, not just audio.

And this highlights a limitation to how the Xbox 360 handles video output. For technical and some licensing reasons, it cannot output HDMI and analog video at the same time.

When the Xbox 360 boots it prioritizes HDMI and tries to establish a connection with the receiving device. If there is no response, it instead checks if there is anything connected to the analog AV port and if so, switches over to analog video output. If nothing
is connected to the analog AV port, or a properly wired audio adapter, the Xbox 360 simply keeps on waiting for the HDMI connection to establish.

The same thing happens if the communication over HDMI is interrupted. If there is nothing connected to the analog AV port or a properly wired audio adapter, the Xbox 360 waits for the HDMI connection to re-establish. If there is an analog AV cable connected,
it reboots so that it can configure itself for analog video output.

To solve the problem, you either have to crack open the audio adapter's connector and re-solder it to make it identify itself as an audio adapter, not as an AV cable. If you have a soldering iron and want to take a crack at this, you should be able to find instructions
on the net for which pins to wire.

Another soloution is to try getting hold of a used original audio adapter, or a third party one that is known to be wired correctly.

Of course the most dramatic and expensive solution is to get an Xbox 360S. As stated by Bill Gates in an interview once: "Microsoft has never been accused of not knowing how to make money".

Hey there,

Try these steps out, and or switch HDMI Coards, or try it as AV, to see if its your actual port

if theres no video or audio, but its turning on, are you sure its not just the av cable?
