A master volume-control window opens. Verify that the Mute settings are not checked and none of the volume settings is set too low. • Some models have a front audio panel you can use to adjust volume. If you have a front audio panel, verify that the volume is not set too low. • Verify that your external speakers (and headphones, if used) are connected to the correct audio connector on the computer.
