guy`s thanx for replying but i solve the problem it was a bios configuration . When i put my graphic card on computer and as u know graphic card`s has they are own sound card`s so bios has change best option for the PC automatically and disable builtin sound card of motherboard . I just restart the PC opened bios configuration and make Integrated Audio Enable ( it was disabled ) and that`s all ! Now sound working perfectly without any problem !
