Updated February 10, 2017 Turn on your computer and access your BIOS settings. The keyboard key in question varies by motherboard manufacturer. Typically, the BIOS key is disclosed at the bottom of the screen during the Power-on Self Test process. Access generally consists of the F1, F2, F10 or the Delete key. Go to the “Advanced” BIOS section. Go to the “Onboard” or “Device Configuration” option by pressing “Enter.” The sound settings are typically under “Audio Controller” or any other similar sound-related configuration. Press “Enter” to enable or disable the sound setting at hand. Note that such options vary by motherboard, although these are the typical settings programmed into a computer BIOS. Press F10 to save and exit the new settings. Writer Bio
