Using a Xbox 360 with a PC Monitor

well, 10 years ago I would strongly advise against doing something like this. Today it might be a good choice...

anyways, depending on what you get the dvi adapter for, you might be able to plug in the audio av cables into speakers. I don't know if xbox outputs to all available ports at once. Basically see if you can use component to speakers audio set up and DVI for video transmission. I don't know if it'll work if they feed off different output modes.

I mean if you use HDMI to DVI, then DVI adapter will have to have the cables separately for sound data, otherwise that just outright signal loss and if xbox cannot output to several modes at the same time you are out of luck.

You need one of these (OPTICAL RCA AUDIO ADAPTER FOR XBOX 360):

and maybe one of these (if your speakers are not digital TOSLINK capable) (2x RCA Phono Male to 1x 3.5mm Female Jack Socket Lead):

Just managed to find the model my speakers are.

I appreciate the replies so far but Hairystuff you post confuses me a little, exactly which of those cables will I need? Is the first link only for the audio? It appears to be HDMI to the Composite type port on the back of the Xbox and as far as I'm aware my monitor only has DVI/D-Sub.

Ok basically this lead has a stereo RCA output for your speakers:

But you also need this so that the speakers can be connected to the Audio RCA connectors on the first link:
