Vista can't split sound through 5.1 speaker,any suggestion on sound card for vista?

[ani123]

riends,my computer is a dual booting one,i've both winxp(sp2) & vista,i've recently bought a foxin 5.1 (6 channels) speaker system that has 1 sub woofer and 5 speakers,my asus motherboard's default audio driver is soundmax,problem is that when i'm on xp i can get distinct sound from all of them,but when i'm on vista i get sound from only subwoofer and the centre one.if i buy a sound card will i have better result with vista?can u suggest me a non expensive sound card for vista?

Microsoft software mixer requires OpenAL sound card compatability
Creative seem to be leading the way here

Have you chosen 5.1 speaker setup in Vista's playback devices?
