If you are using a program that has its own volume control, make sure the volume control is properly set. See the
program's help file for more information.
The volume may have been turned off by the Fn+F2 keys. Press them once again.
The volume may have been minimized by the Fn+F3 keys. Keep pressing the Fn+F4 keys to turn up the volume loud
enough to hear sound.
Check the Windows volume controls by clicking the volume icon on the taskbar.
Your sound output device may have been incorrectly configured. To change the sound output device, see How do I
change the sound output device? (page 200).
