Above is a close-up photo of the audio input/output jacks on the rear panel of my Acer Aspire M1641-E3750A Desktop PC. I think this setup is for a 7:1 surround sound system. When I access the Acer Aspire manual from the PC itself, it doesn't specify exactly which jack is for which function of a surround sound system. I do know the universal audio symbols mean: 'output'-arrow pointing out of wave circle and 'input'-arrow pointing into wave circle. The pink jack is the microphone input jack. The blue jack is the line-in jack. The green jack is for a headphone.
Here are the three problems I'm trying to solve:
1) Which output jack serves what function in a surround sound system?
Since the green jack is for a headphone then on a surround sound system this output would likely serve as the 'Left' and 'Right' front speakers. Is that correct? I suspect that the black top middle jack is the woofer. Is this true? I don't know what role the white and yellow output jacks serve in this system.
2) What is the proper wiring/hook-up procedure to attach speakers to these output jacks?
I think ALL the output plugs are mini stereo plugs. So, do I attach two speakers from each output plug like a stereo headset?
3) Does the PC power the attached speakers in the surround sound system? If not, do I have to patch the outputs from the PC through an amplifier and then output the signals to the speakers?
I apologize for all this detail! Maybe there is a quick reference someone could offer via a link to a knowledge base. I've tried Acer, Wikipedia and other sources but I can't seem to find answers to these questions.
Any help is appreciated. Thanks!
