Percent of machines with at least one audio render stream initialization failure

Description

See "Audio user-mode reliability" on Audio measures

Measure attributes

Attribute	Value
Audience	Audio measures capture data from any machine that is playing audio on Windows
Time period	30 day sliding window
Minimum population	1000 Machines
Machine Vs Instance	Percentage of Machine
Passing criteria	<=1.5 % of machines have at least one audio render stream initialization failure
Measure ID	39415262

Calculation

1. The measure aggregates telemtry from a 30-day sliding window into a percentage of Machines that had a render stream initialization failure.
2. Render stream initilzation failures = Count(machines with render stream init failure)
3. Total machines that played audio = Count(machines that had a render audio stream init event)

Final calculation

Measure failure rate = # of machines with atleast one Render Stream init failure / Total # machines with a stream init event
