I installed audio driver but same message.and volume has a red cross sign. But when i connect an usb audio adapter,everything goes fine.i can hear sounds,can control volume.is there any problem in my motherboard's audio???plz help

USB sound adapters have own sound chip and don't use one on MB. Check Device manager for HD Audio or anything pertaining Realtek ALC662 6-Channel HD Audio drivers. because that's what's on that MB. Also check BIOS, integral sound may have been disabled.
