I have a PS3 connected to a computer led monitor which has no sound output so I have an Logitech 2.1 audio system connected to that monitor. I want to connect the sound sytem to the PS3 but the cable of the sound system is probably for computer (only green audio and pink microphone cable). How can I connect it to the PS3 ? Thanks and sorry for my bad english.
Something like this I imagine: http://www.cablewholesale.com/specs/35mm-to-rca/30s1-01400.htm
Take the RCA audio output from the PS3 and convert it to the 3.5mm jack you need. The adapter will need to be female/female if I'm understanding your cabling correctly.
