Many Windows (XP, 2000, NT, 2003, and even Vista) users are faced with the common problem of there being no sound and audio coming through from the system. Most beginner-level users do not know how to deal with this problem and have to end up paying a lot of money to advanced computer professionals for a job that actually can be done in a matter of minutes by anyone who has the right guidance.

First, you have to know that this problem is most likely caused by a disorganized registry resulting from third-party softwares that often result in corrupt or missing codecs – a component necessary to decode and decompress media files so that Windows can play them for you.

The symptoms of this problem are simple – there is no sound at all! You can’t hear anything right from a mouse click to Windows startup tone to songs to flash media on the internet – although the video playbacks are working fine. If you have a no-sound issue with only Flash objects then try to fix the Flash sound registry file as shown here. In other cases, all you have to do is follow the steps below.

· Download and install K-Lite Codec Pack version 3.3.0. If you don’t need the features of the pack as such, deselect all components except Codec Tweak Tool under the Tools section.

· After installed, click on Start button, then go to All Programs -> K-Lite Codec Pack -> Configuration -> Codec Tweak Tool.

· In the Codec Tweak Tool window, tick the check box next to [Registry] Fix non-working system sound.

· Click on Next button, and your Windows no sound problem should be fixed, and working as usual.
