help needed connecting 360 to monitor

I connected my 360 to monitor.Now problem is there is display but no sound.I use a VGA cable to connect to monitor.And my monitor doesnt has any audio inputs.So i connected my two red and white cables of audia in to a coupling which i then connected to my PC speakers but still no sound.

Can any1 help??

Ofcourse they work.There must be something i am doing wrong

Try another coupling if you have one, if not here is one that is quite cheap. Also if you have a TV that has a PC input you may want to test audio on it, you could have a bad 360 VGA cable.
