Whats That Sound?????

Ok so have a ASUS M4A88T-M MB and it is showing I need the VIA Drivers. I can only find ones for Win 7 so done the compatibility mode thing and now I have sound but its just fuzz in a tin can.

Any help would be grateful as I am running Win 8 CP as my main OS right now.

PC Info
Asus M4A88T-M
AMD Phenome II x4 955
4 GB Ram
ATI Radeon HD 5850

Sound is via the 6 sound jacks not the optical or HDMI any other info needed please ask
