That audio track is hiding itself somewhere...

Uninstall the codec packs.
The use DXMAN to remove the crap codecs that the uninstaller missed.

And never use a codec pack again.

The problems jairovital had do indeed seem to be due to codec conflicts.

However, not as far as I can see because of a codec pack, but codecs installed by media players.
Thus his problem was not solved when he did uninstall K-Lite.

The only codec involved that was installed by K-Lite was ffdshow, which is universally recommended, and that was working.

A major benefit of a good codec pack are the tools they include for managing such conflicts.

If you have a deep understanding of the process of course, you can do it all by hand.
