Percent of machines with at least one audio stream initialization failure

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 machines
Minimum population	1000 machines
Passing criteria	<=2 % of machines with at least one audio steam initialization failure
Measure ID	39415055

Calculation

1. The measure aggregates telemetry from a 7-day sliding window into a percentage of machines that have at least one unexpected initialization failure
2. Machines with itialization failure = Count(machines with at least one unexpected initialization failure)
3. Total machines = Count(machines that attempted to initalizate an audio stream)

Final calculation

Percent of machines with at least one stream initialization failure = Machines with initialization failure / Total machines
