The Windows Audio Team has developed several new measures to facilitate the evaluation of audio drivers.

 

Measure 39415262 is used to track audio client initialization (ACI) render stream initialization failures. Our measure will track the percentage of devices with at least one ACI render stream initialization failure. 

Audience Audio Measures capture data from any machine that is playing audio on Windows
Time Period 30 day sliding window
Machine vs. Instance Percentage of Machine
Passing Criteria <=1.5% of devices have at least 1 audio render stream initialization failure

 

Measure 39415321 is used to track audio client initialization (ACI) capture stream initialization failures. Our measure will track the percentage of devices with at least one ACI capture stream initialization failure. 

Audience Audio Measures capture data from any machine that is playing audio on Windows
Time Period 30 day sliding window
Machine vs. Instance Percentage of Machine
Passing Criteria

<=1% of devices have at least 1 audio capture stream initialization failure

 

Measure 27539296 is used to track audio client initialization (ACI) render failures. Our measure will track the percentage of device endpoints with at least one audio stream initialization render failure. 

Audience Audio Measures capture data from any machine that is playing audio on Windows
Time Period 7 day sliding window
Machine vs. Instance Aggregation of machine endpoints
Passing Criteria <=1.5% of machine endpoints with at least one render stream initialization failure

 

Measure 27539331 is used to track audio client initialization (ACI) capture failures. Our measure will track the percentage of device endpoints with at least one audio render stream initialization capture failure. 

Audience Audio Measures capture data from any machine that is playing audio on Windows
Time Period 30 day sliding window
Machine vs. Instance Endpoint level on a machine (each machine can have more than one audio endpoint).
Passing Criteria

<=4% of devices have at least 1 audio capture stream initialization failure

 

 

Measure 26628516 is used to track audio client initialization (ACI) stream failures. Our measure will track the percentage of device endpoints with at least one audio stream initialization failure. 

Audience

Audio Measures capture data from any machine that is playing audio on Windows

Time Period

7 day sliding window

Measurement Criteria

Aggregation of machine endpoints

Minimum Population

1000 machines

Passing Criteria

<=2 % of machine endpoints with at least 1 audio steam initialization failure

 

Measure 27657901 is used to determine an audio stream initialization success rate for each machine and calculates a percentage of machines with less than 90% stream initialization rate. When an application is unable to initialize an audio stream, the user will not have access to the application’s audio experience.

Minimum Population

1000 machines

Passing Criteria

<=0.5% of machine endpoints with at least 1 capture audio steam initialization failure

 

Measure 29568277 is used to track the percentage of audio device endpoints that cause a system crash.

Measurement Criteria

Aggregation of machine endpoints

Minimum Population

1000 machines

Passing Criteria

<=0.3% of machine endpoints with at least 1 crash in AudioSrv or AudioDg

 

Measure 29745823 is used to track the percentage of audio device endpoints that cause a system hang. 

Audience

Audio Measures capture data from any machine that is playing audio on Windows

Time Period

7 day sliding window

Measurement Criteria

Aggregation of machine endpoints

Minimum Population

1000 machines

<=0.5% of machine endpoints with at least 1 hang in AudioSrv or AudioDg

These measures are currently in evaluation for the next 30 days. They will become active for making driver approval decisions on 12/19/2022.
