I am using a LaVie G laptop model PC LG26NRCGM. The specifications in the manufacturer's web site indicated that the chipset is SiS 963L and that the audio device driver is SiS7012. I downloaded the specified driver but it won't work. a message appears on screen : "UpdateDriverFoPlugAndPlayDevices -536870397.a Aready i have instaled AC97" Driver but yellow "?" showing in the "Multimedia Audio Controler". What should I do. Please help...
