Windows xp – Stereo sound through whole 5.1 speaker set – is it possible with winxp or 7?

Is it possible to “upmix” (split) stereo output from games, winamp, youtube and so on through 5.1 speaker set? Movies from DVD or some games uses all 6 speakers, but most of today’s usage does not.

I know foobar2000 can upmix stereo MP3 to all speakers, I’d like to process all stereo sound that way.

Is there any solution for Windows XP or 7?

EDIT:I’m talking about onboard 5.1 sound output AC97 nForce2 chipset in my case. Definitely low-end.EDIT2:No digital output, 3 analog mini-jacks there.

Solution:

As Skelly says, it would depend on your driver.

For me, it’s this setting:
