My Intel Q67 or Q77 Based System Suffers from Audio Skipping or Glitches, How Can I Fix This?

Problem

An Intel Q67 chipset or Intel Q77 chipset based system may experience the following issues randomly:

Cause

This issue is caused by the design of the Intel LAN driver and the way it interacts with the Q67 or Q77 chipset management engine. These issues can appear even if the management engine has not been configured, i.e. the management engine is "un-provisioned".

In the case of the Intel DQ77MK based system, the problems only affects the Intel 82579LM controller. Using the 82574L secondary LAN controller and leaving the 82579LM controller unplugged will work-around the issue, but this will prevent the use of AMT technologies such as VPRO remote control.

Note: The audio or video being played does not need to be being transferred over the network; the 82579LM adapter simply needs to be plugged into a network to cause the problems in the system.

Resolution

Ensure that you use the Intel Pro 1000 driver Release 19.1.

If you have an older driver already installed:

If you have a newer driver already installed:

The correct driver based on the 19.1 package has a version number of 12.10.28.0.
