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.
