Event though the media file starts playing in the GPUProcess, its current time never changes (stays 0). 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.

This is due to sandboxing. Fixing now.
