Solve : PC Connections?

Answer»

Desk top PC eMachines ET1161-7
On the BACK of the case there is a row of sockets/outlets  Pink, green and Blue. what is the function of those?
another row has Gray/white,  Black and Orange.   The Gray/white could be AUDIO in. Black,Orange unknown.
(Trying to connect PC without installation INSTRUCTIONS) Sounds like you are describing the Audio connections.

Lime Green= Speaker out
Blue = Line In
Black = Rear Audio (4.1,5.1,7.1 Audio)
Pink = Microphone
Gray= Side Surround out (7.1 Audio)
Orange = Center/Subwoofer out (5.1 and 7.1 Audio).

If you are looking to plug in a pair of SPEAKERS than you will want the Lime Green JACK.
