M2N-SLI & CM6501 Sound Problem

[Madrugada_Gr]

Hello Forum ,

i have the M2n - sli M/b and use the creative x-530 speakers
until recently i was listening to any kind of music / movies / games Fine

today i tried updating the Drivers and then....! i had no sound for the rear speakers and the center speaker

after lon searching i found about some USB design that ASUS is using

it didnt help much cause im using no from pannel USB ,

Do i have to Disconnect my USB devices ?

I cant place another xtra sound card cause my SLI dual 9600gt are blocking all the slots !

i even tried Uninstalling the sound card and installing other ones older and newer many times but still ... no sound ?

should i Refer to the retailer or asus to get a new Mo/bo ?

But , even if i get the same ? wont i have the same problem again ? Or is it Just vista ? !

i want my sound back

thnx in advance
thanos
