New Audio Measures

To improve our capabilities in evaluating driver quality, the Windows Audio Team has developed several new machine endpoint measures along with updates to the existing system level measures to facilitate the evaluation of audio drivers.

 

Updates to existing measures

As our targeting abilities have improved, we have identified several legacy measures that are in the process of being replaced with new measures that will more comprehensively test for the same passing criteria:

 

Evaluation

Legacy Measure ID

New Measure ID

Percent of machines with at least one audio crash

23032999

38373370

Percent of machines with at least one audio hang

11458540

38880837

Percent of machines with at least one audio stream initialization failure

12111510

39415055

 

While these new measures are coming online, the existing legacy measures will continue to be used and reflected in reports shared with driver publishers until they are phased out in Q1 2023.

 

New measures

In addition to leveraging system level measures, Microsoft can now evaluate driver quality at the machine endpoint level. The following measures are currently in evaluation for feedback through 12/21/23 and will be operationalized into Driver Shiproom publishing decisions in January of 2023.
