When viewing news video (and others) the lips move and the sound follows after a few seconds. How do I fix this?

The movement of the lips when a video plays is not synced with the verbal noise that comes from speaking. It's like if I am talking and I hear it moments later not when I actually say it.

This happens when I view Fox news, cnn or any of the local news stations.

You can try to disable hardware acceleration in Firefox.

  • Tools > Options > Advanced > General > Browsing: "Use hardware acceleration when available"

You need to close and restart Firefox after toggling this setting.

Try to "disable the hardware acceleration" in the Flash Player.
