How to get 2.1 speaker setup from integrated Realtek HD audio?

[Goi]

Hi,
I have a DFI X48 mobo with integrated Realtek HD audio hardware. I also have a 2.1 speaker/amp system with a power amp, 2 passive stereo speakers and a powered sub. I've plugged the power amp to the L/R channel output, and the powered sub to the center/sub output, but under Control Panel->Sounds, there's no 2.1 option...only stereo, quadrophonic, 5.1 and 7.1. If I choose stereo I lose my subwoofer, if I choose 5.1 I get the center channel piped to my subwoofer. Is there anyway to fix this?

Probably a pretty silly idea, but you can always connect your sub to L/R stereo and get front speakers input from sub. Let the sub do the crossover. Otherwise I'd try 5.1 again, use 3.5mm jack Y-Split cable to RCA, and connect it to sub, one of them should be center and other sub

I do believe there is a way to manually tell each port what it's output is. If that doesn't help what about the windows audio setup in contol panel. That has 2.1 i believe.

you must use the drivers that came with the board, not the windows audio setup. you should have another audio related icon in control panel. if not, download and install the drivers for your sound codec/chip and install them, you will be able to assign each port to what ever you want.

Yes I have installed the drivers. The problem now is mixing stereo information into the subwoofer channel. Is that possible? I didn't see any such option in the realtek control panel.

just set the software to 2.0 stereo, and get a splitter for the green output on your computer. Run one cable to front left/right, and the other to your sub. The sub (or the receiver) will filter out the higher frequencies...

Thank you, this is exactly what I said above in different words..

If you have good speakers I would reccomend getting a sound card.

Realtek HD Audio also has SPDIF and Optical (not sure if your board does) which would be better to use rather than L/R and SUB if your "amp" has digital inputs and can decode and pass out LFE
