Why does video slow down and speakers make a buzzing sound when I use the touchpad?
When you use the touchpad, your system reacts slow, or makes a buzzing sound when playing video. This behaviour started after installation of updates from Windows Update.
Uninstall the Intel Technology Access program to resolve this issue. You can find instructions for uninstalling programs in our support article .
The offending update has been removed from Windows Update. After removing this program, or after re-installation of your system, the issue will not occur again.
