Fix Windows No Sound and Audio Problem

Ever had the problem when windows system does not give you sound and audio suddenly or despite sound card or audio device is present and working previously? Windows XP, 2000, NT, 2003 or even Vista computers may lose Windows audio and system sounds output due to the mess on file system or registry that created or left by third-party utilities after installation and uninstallation, or corrupted and missing codecs, (a CODEC is a component necessary to decompress and decode media files so that they can be played back by Windows).


When the Windows “no sound problem occurs”, the symptoms include users do not hear any Windows system sound even though the volume control on speakers have turned on, and all audio mixers and EQs are not muted. Users cannot hear sound from mouse start navigation clicks, Windows startup sound, messenger’s user online or incoming message notification alert and etc. Even Flash video clips hosted on YouTube, Google Video, Dailymotion, CNet Video, MetaCafe, and etc will not output the sound, even though video playback fine without problem.


Here is a simple trick to fix Windows system no sound problem. The trick works by using a tool built into K-Lite Codec Pack.

  1. Download and install K-Lite Codec Pack here, or choose other versions from more mirrors here. You can deselect most components that you don’t need, except Codec Tweak Tool under the Tools section.
  2. After installed, click on Start button, then go to All Programs -> K-Lite Codec Pack -> Configuration -> Codec Tweak Tool.
  3. In the Codec Tweak Tool window, tick the check box next to [Registry] Fix non-working system sound.
  4. Click on Next button, and your Windows no sound problem should be fixed, and working as usual.
