The basic input/output system on an ASUS motherboard controls which on-board devices are enabled after the computer boots. Some ASUS motherboards have an option in the BIOS that allows users to enable or disable integrated audio. If integrated audio is disabled, the computer won't play sound. If the BIOS settings are correct, but the computer still doesn't play sound, the audio cables might not be connected to the speaker jacks on the computer case or disc player.
