Windows 7: PCI Sound Card drivers not working

Hey guys, I recently upgraded to Windows 7 Prof 32bit, after installing it I relised I can't get surround sound with my onboard sound like I was able to with XP. I went out and bought be a genius 5.1 surround sound PCI card.

Now the thing is...before installing the genius drivers, Should I first unstalled the drivers that came with Windows 7 and if i should how do I go about doing that.

I installed it thow, but at the moment when I enable 5.1 sound in my controle pannel only the front speakers work while playing music through WMP, I do however get surround sound in games and dvds, to get sound through all the speakers I have to select stereo sound again in the controle panel.

When I make any changes on the sound program provided by genius nothing happens. Think there might be a driver clash or something.

Please HELP.....

uninstall the original drivers and install the latest avaible drivers for your soundcard if needed install them in compatibility mode.

Do you mean the drivers that came with Windows 7? If you do How do I unstall it, can't seem to find the place do to so...

just go to device manager, n search driver sound card then right click uninstall.

That is exactly what is supposed to happen. Unless your music is being played from a DVD-A or was encoded in 5.1 all it will playback as is stereo. You want music to play in 5.1 you have to use some form of upmixing; CMSS3D on Creative cards, Stereo Surround/Fill/Expand or something similar on other sound cards, or Dolby Digital Live (or DTS Connect) if it is supported by the card.

Ok thats understandable but why didn't I get this problem on my XP machine?
5.1 sound worked and when I played a mp3 which is stereo I got sound from all the speakers?

Can you provide me with a solution regarding your statement? I tried fill but it sounds real crap....

Guys.... I've tried everything, I unstalled every single audio driver on my PC, then I installed the Windows 7 compatable drivers for my sound card ( which I downloaded), and guess what...ALL I COULD SEE IS HORIZONTAL LINES AND BOOOOOF GOES THE PC,(restarted on its own) so I reinstalled my old sound drivers...ow by the why, after installing the new drivers nothing changed relating my sound, its the same as what I mentioned in my initial post.
So know I'm back to stereo sound which on 5.1 mode only comes out the front left and right speakers
