I have an Intel DG965RY motherboard with onboard 5.1 audio that's I'd like to connect to a receiver. The back panel only has 3.5mm line out, line in, and mic jacks. No coax or optical outs. If I connected that output to L/R RCA inputs on my receiver, would the 5.1 make it through?

I'm guessing the 3.5mm is analog 1V peak to peak, not sure. Doubt there is multiplexing or encoding or anything like that. Probably only going to get two channels that's it. Maybe more advanced motherboards have 5.1 capability.
So, to be honest, I don't know but I'll watch the thread to learn myself.

Well the specs for the motherboard claim 5.1 audio support. But I'm wondering if this board's chip has more capability than the I/O ports they soldered on. |

3.5mm jack is stereo only. Not 5.1. It wouldnt work. Need multiple jacks, or optical out. |

If using six speakers:
* Connect the front left/right speakers to connector (B).
* Connect the rear left/right speakers to connector (A).
* Connect the center/subwoofer speakers to connector (C).
* Using the audio driver interface, retask connector (A) to be Rear Left/Right Out and retask connector (C) to be Center/LFE Out.

That is an interesting setup for those boards.
But it will not be useful for many home theater receivers because they want digital audio signal, not six analog signals. Most low to medium cost receivers today do not have analog surround sound inputs. Older Dolby Pro Logic receivers without Dolby Digital had these inputs because some of the CD players had the Dolby Digital decoders built in.
The typical home theater receiver today has the following connections for each input:
Analog audio (left/right and red/white RCA)
Analog composite video (yellow RCA)
s-video (s-video connector)
Digital audio (RCA coax and/or Toslink optical)

My receiver actually has 8 channel analog input. I have a 3.5mm to RCA cable on order so I'm going to try that first and see how it sounds. I only have 3 channel (L-C-R) speakers right now anyway so if the receiver can synthesize the center channel out of the L/R inputs, it'll get the job done

You are in luck with the analog inputs.
Do not expect a valid center channel. There is NO encoded surround signals in the analog L/R signals unless your sound source and the sound card will generate Dolby ProLogic encoding.

Well I got my patch cord (3.5mm to L/R RCA) hooked up tonight and it sounds pretty good. I have a nice Yamaha receiver and the DSP is creating a center channel from the L/R inputs.
