I think this should be a 3-state enum, probably with a different name like m_audioPlaybackPolicy.
enum class AutoplayPolicy {
    RequireUserGesture,
    AutoPlay,
    AutoPlayWithoutSound,
    Default, <-- This name might need to be more descriptive indicating that the policy hasn't been set by the WebsitePolicies so default to the Settings value.  Maybe just a comment explaining this.
    etc.
}
These two could probably even be made into one enum

Let's get rid of this now that it doesn't do anything for other platforms.
