I have a new system using ASRock sis746FX on K7S8X mainboard. The onboard includes integrated sound. I have added 1 AIW Radeon 7500. The sound is C-Media and the Cd includes the drivers for loading the media controller which does load properly. However, the disk stop at 94% while attempting to load the audio drivers. As a result I have absolutely no sound. Device ,amager shows everything correctly loaded excluding the audio drivers. I have tried to load updated drivers but they stop at 94% also. I have uninstalled the controller time and again but the same problem reoccurs. I'd be grateful for any suggestions. Thank you.
