Windows 7: Video and audio not in sync.

08 Dec 2012   #1

Windows 7 Home Premium 64bit
Video and audio not in sync.

Hello everyone, does anyone know what this problem could be? Since the first day I brought my computer home the audio and video have been out of sync for video and video games. The audio is ahead of the video, not by alot but it is noticeable. I use VLC 2.0.0 to play all my video (it's not in sync with WMP either) I try to manually re sync the audio in VLC and get good results. Can I fix this or am I stuck with it? Thanks in advance for any help. I have only tried re sync with vlc to fix this.

This happens for .avi, .mkv, mp4 and when streaming and videogames.

I use VLC for every file and have not installed any codecs for WMP.

From device manager> sound, video and game controllers

When I click properties for each on it looks as if they are all enabled, will disabling realtek do anything?
