Missing audio


  • You can see the video, but you cannot hear the sound 

Detailed information

If you are unable to hear audio playback when using LearnKey courseware, then checking speaker power/volume, adjusting the sound card configuration, adjusting the system volume sliders, closing background programs, or verifying your hardware setup will usually fix this problem. 


Close all other applications that are running on your computer. Use the No sound in Windows tutorial at http://windows.microsoft.com/en-us/windows/no-sound-help to resolve the problem. This tutorial will help you to perform the following tasks:

Check your speaker power and volume

Update your sound card drivers
