Introduction: How-To: Xbox360 HDMI & RCA Audio

I'm sure I'm not the first to be disappointed by the placement of the output ports on his Xbox360, specifically how the old trapezoidal A/V cable plug blocks the HDMI port on the Elite models.  And Microsoft, being the conniving #$%^ers they are, have come up with a handy $49.99 solution to the problem that just so happens to be entirely irrelevant.

My problem came about because I wanted to hook my 360 up to my 22" widescreen monitor which doesn't have audio.  Obviously I didn't want to play without sound and my attempt to plug the HDMI cable and the A/V cable in simultaneously met with futility.

My solution involves modding the Microsoft Composite A/V cable, which should have come standard with the system.  I realize now, after doing a quick Google search, that there are a few other tutorials online on how to do this so I don't claim any credit for originality.

Step 1: Tools & Materials

You will only need a couple things for this quick mod:
  • Small, thin flathead screwdriver
  • Electrical tape (optional)
Also, to get this to actually work, you'll need the Microsoft Composite A/V cable and an HDMI or HDMI to DVI cable.  I have not tested the MS Component A/V cable so I cannot comment on it's modability.

Step 2: Mod the A/V Cable

This step is so simple it's a wonder Microsoft even thinks they can get away selling an overpriced peripheral when you already have what you need included with the system.

Find the seam on the connector for the A/V cable, wedge the screwdriver in there, twist, and crack that plastic shell open.  You'll probably have to do it on both sides of the connector, no big deal.

Once the shell (and oh, so much empty space inside the plastic that does nothing) is off, use the electrical tape to keep the metal connector attached to the remaining plastic shell.  Note, it will work without the tape, but it's probably a good idea to electrically insulate that a bit.

Step 3: Plug It In!

Now take that bad boy and plug it in where it's supposed to go.  Then take your HDMI cable and find that, oh would you look at that, there actually is room for the both of these Microsoft!  Now we just have to hope they don't issue a patch to the operating system that makes this mod unable to work.

Does this still work?

Can someone help me, cause all i have is a hdmi and my Macbook Pro and i just wanna play my games but i have no clue how to do that. Any Advise?

Yes, you could do it with a USB video capture card, but I don't know how much lag you would have to do so.

Man u r genius, i use hand saw on wider side av cable, cut the plastic top and brush it and hdmi is plugged under...and 1080 video + av hifi thanx

As i am a bit of a noob here... can anyone explain what i need to do from this point to actually get audio from my PC speakers once i have both cables connected?

Does this still work or have they instated a patch? Also, you have had no issues with the xbox putting out two video signals simultaneously?

works on any 360. friend of mine with a slim did the same thing. worked great.

I haven't used this particular hack in a while since I now have an LCD TV to play my XBOX on, but as far as I know it should still work.

Okay, thanks. I"m going to test it in a few days and post back.
