Nit: `trackMatchesKind` is slightly awkward. Maybe `isKindOfTrack`, or `isTypeOfTrack` instead?

Nit: `Kind` doesn't seem right. RealtimeMediaSource's `Type` is analogous, so how about `MediaCaptureType`?

I think `pageMutedState` would make the logic easier to follow.

Don't you want to just add the muted flag:  `mutedState |= WebCore::MediaProducer::AudioCaptureIsMuted`?

If the page microphone capture state is already already muted, why not just call the completion handler immediately and return?

Ditto the comments above.
