I solved it I´ve found that 'High Definition Audio Codecs Audio drivers available for download from the Realtek website are general drivers for our audio ICs, and may not offer the customizations made by your system/motherboard manufacturer. To be sure you obtain the full features/customizations provided in your original audio product, please download the latest drivers from your system/motherboard manufacturer's website.' At So, you´ll better surf on to AC´97 and to and you´ll find drivers.
