Picture of 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.

This is the reason why it won't work with some of the Component/Composite cables, as there is a fair amount of hardware in there, probably to switch between HD and SD, on the X801255-100 cables.

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.

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.

I used one of the A/V cables from a 360 Slim. easier to pop apart. Worked great Using my HD PC monitor and my PC speakers for sound. I did go an extra step and and plug the xbox sound to the LINE IN and use my leyboard audio buttond to adjust the volume. Thanks so very much for the idea. Now the wife can watch TV and I can still play my xbox whenever I want.

I had exactly the same problem, so I bought this cable for $7.
So long as you have a 3.5mm extension cable, or your speaker input is nearby, it works very well.

I did the same thing too but I found the signal degraded with the VGA connection.  Probably because it's analog and DVI/HDMI is digital.
Could also be your display. The VGA connections on my main screens look better than the HDMI.
I don't think it' his display... On really good screens, digital signals are always better than analog signals.

My monitor only has VGA in so this was my only choice - works absolutely fine for me though.

Thank you for this. I had originally thought that tab was there because of potential damage to your console for using both ports (come to think of it, might still not be a good thing if you plug in HDMI and component video at the same time), so I bought the HDMI kit. But now that I know that such is not entirely the case (and that there is actually nothing in that part of the casing), I can mod the composite cables gathering dust on my shelf for this purpose.

Microsoft needs to work on where they put the connections I AGREE REALLY MICROSOFT
Pretty sure Microsoft set it up that way intentionally, as most will buy a cable before modding a current one. I agree that the placement is evil, but that's Microsoft

Nice hack, takes all of 2 minutes. I cut off the offending tab with a hacksaw very easily and just re-assembled the connector taped with packing tape. Easiest $50 I didn't spend ever.
What would happen if you didn't put any electric tape or anything on it?

not trying to be a prick, but why didnt you simply grind off the tab, allowing the plastic casing to keep the internal already insulated?
frazeeg (author)  yomammah3 years ago
It was probably a combination of the fact that I didn't know it was just empty space behind the tab and the fact that I didn't want to get melted plastic all over my grinding wheel.

Awesome I did not know this was possible. My tv does not have audio out and the speakers are weak. This will totally make Rock Band 100% better.
