Consider the following scenario. You watch Live TV or a DVD in Windows Media Center on a computer that is running Windows Vista Home Premium or Windows Vista Ultimate. You pause the video. Then, you use the Start menu, a sleep button on a keyboard, or a Windows Media Center remote control to put the computer to sleep. Finally, you wake the computer and then try to continue watching Live TV or the same DVD. In this scenario, you can view the video in Live TV or on the DVD. But you cannot hear the accompanying audio.

Note: You can still hear audio in Windows Vista, in Windows Media Center, and in other programs.
