I'm trying to write some code that plays sounds from the watch speaker. Ideally, I'd like to use WKAudioFilePlayer since it can play audio files in the background, but it seems to only support Bluetooth speakers. The other option is to use presentMediaPlayerControllerWithURL:options:completion: but it pauses the audio when the screen shuts off, and there's no way to ask for the screen to stay on, making this API almost useless.
Are there any other options for playing audio through the speaker?
