Percent of machine endpoints with at least one audio render stream initialization failure per driver

  • Article

Description

See the "Audio stream initialization" section at Audio measures

Measure attributes

Attribute Value
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 <=1.5% of machine endpoints have at least one audio steam initialization failure
Measure ID 27539296

Calculation

  1. Measure is accounting for failures at an endpoint level, that is, if there is a failure on a specific endpoint that the driver is targeting, it is counted as a failure.
  2. The measure aggregates telemetry from a 7-day sliding window into a percentage of machines’ endpoints that have at least one unexpected initialization failure
  3. Machine endpoint with initialization failure = Count(endpoints driver is targeting with at least 1 unexpected render initialization failure)
  4. Total machine endpoints = Count(machine endpoints targeted by driver that attempted to initialize an audio render stream)

Final calculation

Percent of machine endpoints with at least 1 render stream initialization failure = Machine endpoints targeted by driver with render initialization failure / Total machine endpoints targeted by driver
