Yesterday , I Bought a gigabyte 78lmt usb 3 . My first question is ! does this motherboard has realtek Audio card ? or it has its own integrated audio card ? I downloaded realtek azalia ati from their main site after selecting my motherboard and os . After installation system reboots . still there is no realtek in control panel Hardware and sounds .but it is there in uninstall a program in control panel .... and i went to C:\Program Files (x86)\Realtek then the audio folder size is only 3 mb ? why ? my sound is working but . where is realtek ? ,,either the driver is not installing or the hardware of realtek is corrupted ?. and there is no process of realtek running in task manager . and yes im using windows 7 64 bit !
