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
- 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.
- The measure aggregates telemetry from a 7-day sliding window into a percentage of machines’ endpoints that have at least one unexpected initialization failure
- Machine endpoint with initialization failure = Count(endpoints driver is targeting with at least 1 unexpected render initialization failure)
- 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
