base::UmaHistogramEnumeration(This histogram will not be logged if the feature is turned off, so it cannot be used to measure the size of the change in an A/B comparison. I suggest a histogram that is logged with equal frequency for both the enabled and disabled groups.
This histogram could be as simple as a boolean "Media.Audio.Capture.Win.InitializeSucceeded", which just logs whether initialization succeeds (similar to Media.Audio.Capture.Win.InitError.SystemPermissionDenied). This is good because that histogram conversely also proves that initialization doesn't regress.
If you are interested in how often retrying succeeds we can keep this histogram as well.

Added a boolean UMA as well to track success with and without the experiment.
