Use something like this circuit as I described above :-

Simple Line Mixer

You'll need two one for the left outputs and one for the right outputs.

Most cheap mixers only use resistors. There will be slight feedback but not enough to make any significant difference.

If you really want to try something more complicated you can try something like this :-

Stereo Mixer

The problem is this circuit needs a split rail supply. + and - 9V because the opamp has to drive the signal positive and negative just like the audio input coming from the xbox or cd player. The xbox doesn't have a -ve supply voltage from the power supply so you would need a converter. Stick with the easy option of the first circuit.

look it up.
There is no such component.

DO NOT USE diodes it wont work.

Read this

Pay careful attention to the paragraph at the bottom of the page. "Can I use diodes in this circuit instead of the resistors ?"

realy?
than what the hell is this?

capacitor

but i will say you were right about the whole diode thing. i sometimes forget that ac goes back and forth, i keep thinking ac in wave length terms.

and then do the same for the right channel?

Yeah but a "compasiter" isn't a "capacitor" is it. I didn't realise it was a spelling mistake sorry.

Connecting a capacitor  in series would block any DC offset on the audio signal while allowing the AC part to pass. I should imagine there are already in line capacitors on the xbox's output stages anyway.

d34th_r3c0n wire it like this :-

wait... is that schematic for mixing them then sending them through the A/V cable from the xbox to the tv?

if so why would i need a resistor from the xbox? wouldnt there already be one in there somewhere? would i have to wire one to the mobo?

it seems that that is for going from the xbox to another output while mixing in the cdplayer...

The way I showed is the correct way to mix to signals together. The resistors are there to avoid overloading the outputs.

Without breaking the signal from the connection points on the motherboard to the AV socket i don't think you will be able to do what you want to do. You need to get the signals from the xbox mix them together with the CD player and then output to the TV.

do you know of any way i could do that from the inside... so it still goes out the A/V plug?

The only way would be to break the track on the motherboard. Not a good idea.

Another way would be to make a small scart to scart extension cable and tap of the xbox audio from there.

All i do is i have my Xbox running from my TV speakers, and my Ipod running from ym good speakers, turn the TV sound off and pump my good quality music with my iPod.

Easy as that.

I'm pretty there's no way to have any kind of audio or video input (through the A/V port) on the Xbox, because I remember this being asked before.

If you wanted to hear the audio from your CD player while you're playing a game, you could probably solder to the audio left and right points on the bottom of the motherboard:

But, like you said, it would probably be a lot easier if you connected the CD player to the Xbox A/V cord.
