The media is definitely in PLAYING state, not paused. Interestingly, bypassing RemoteMediaPlayerProxy::setShouldEnableAudioSourceProvider() seems to unblock media playback as I see the current time changing. It must be an issue with the provider somehow. 1721223 3 cdumez 2021-01-21 10:17:56 -0800 This is due to sandboxing.
