Ok, so this problem has been bugging me for a while now. I have a set of Logitech R 20 speakers (2.1) and I'm quite fond of my subwoofer. But once I installed Windows 7, it stopped seeing my speakers as 2.1 speakers.
Currently my motherbord is a Gigabyte 770TA-UD3, but even hen I was using a Gugabyte MA770-US3 it had this problem. Both motherboards have Audio Out for Front Left and Right, Side Left and Right, Rear Left and Right and Center Subwoofer. But on the MA770-US3, when I was running Windows Vista it would detect the subwoofer perfectly.
Curently when I try to configure my device in the Audio Panel, I get these options
I've installed all the lasted Motherboard Drivers, and the motherboard is Windows 7 compatible, and this problem has occurred on all the fresh installs that I've done. When I try to google the problem, I get a couple of entries about this, and then it seems like the rest is just advertising/reviews.
Can anybody please help me?

I have an Asus motherboard on XP, with R-20, and the Realtek audio offers 2CH, 4CH, 6CH, 8CH and headphones as options for what is plugged in to the jack.
It never even occurred to me that it should detect or offer 2.1
Maybe it does not matter, because the subwoofer is really handled by the speakers themselves, presumable by a low-pass filter on the combined channels. I don't think the PC would do anything differently if it knew it had a subwoofer.
P.S. the R20 is a brilliant speaker IMHO

You may have to pick 2CH or Stereo.
The subs audio is a mixture of the left and right audio anyway.
I believe Logitech has posted cures saying use 2CH; 2.0 or Stereo.
My Realtek HD sound applet in XP only has a 2CH speaker or headphone choice if I am not 4CH; 6CH or 8CH speakers.
