Need to connect my pc to my 5.1 surround

[Eoyu]

Hi ! I need to connect my pc line out (headphones stereo jack) to my 5.1 surround system (3 input line purple-green-black). I don't want that the surround effect, just the stereo effect. I dont want to buy some expensive stuffs. thaks a lot ^_^
( i already tried to make a jack with a top stereo, and the other with 3 jacks, but i have noise when the cable is connect to a pc)

All you need is to get a 3.5mm to RCA adapter it will cost you 1 or 2 USD and you can get stereo output

Yes but my speakers have not the input in rca. i have 1 jack that comes from pc (stereo) and 3 jacks needed in the speakers. (and i cannot find an adaptator on sale ) Thanks for help

the cable is right, but the speakers has jack input hole. ( http://i.testfreaks.it/images/products/600x400/98/trust-soundforce-5-1.2093410.jpg see the first 3 holes? there are jack, not RCA ) maybe i can cut the lines and paste them to 3 jacks, but i prefer to buy the right cable and do not spend to much time in this. thanks ^_^ let me see !!

Just use a 3.5mm(stereo) to 3.5mm(stereo) cord and plug green(line out) to green.

For your future reference, Jack is a connector in electronic term. so when you keep on saying jack, RCA plug can also be called jack. It has a proper name and it is called TSR connector or mini plug to spicify the type of connector. As ien2222 pointed out the size of connector on his link 3.5mm or mini plug. a 2.5 mm TSR is called micro phono jack or micro headphone jack/plug.

Ok but... do you have a solution?

Just use a 3.5mm(stereo) to 3.5mm(stereo) cord and plug green(line out) to green.

For example:

If i do this not all speakers work. Just one channel !

 

[ien2222]

His solution will be the same as mine, stereo 3.5mm to stereo 3.5mm.

On your sub the three inputs are stereo 3.5mm: Green, black, and purple. Green is L/R, black is sub/center, purple is rear. You said you only wanted stereo so all you need to do is plug the cable into your line out (which is probably green) on your computer and then plug it into the green on your speaker system.

The noise you are hearing is the noise coming between two power supply. Your PC and your speakers. Few things you should try to eliminate the noise but first is your connection.

1) Buy and try to connect the cable ien2222 suggested with your phone or ipod or something and just run it through its battery. If the signal is clean then it is the ground from the both unit is causing the noise.
2) You can try using a ferrite core if that works, however, it is not 100% guaranty it'll work. https://www.youtube.com/watch?v=_cUt9DSJDpc
3) More expensive connection is optical connection. You only need to do this method if you really love your speakers because it'll cost around $30 to $100 if you chose this path. For that you can use something like this for your speaker. http://www.amazon.com/D3-Digital-Converter-Optical-Toslink/dp/B005K2TXMO/ref=sr_1_3?s=electronics&ie=UTF8&qid=1420808221&sr=1-3&keywords=fiio+dac
plus, you'll optical output from your computer if you don't have yet. And this will not guaranty it will work because you still need to connect to power, and if the signal between the DAC to your speaker is noisy then you are back to square one.

with that 2 channel will work, left and right channel. Just plug it in to where the front channel socket of your speaker signal input not the one goes to your speaker. This I assume the RCA jacks are for speakers or is it "Audio IN / INPUT" as well?
