WatchKit: system sounds allowed?

Question

I've been reading some posts regarding playing sounds in an Apple Watch and it looks it is not possible... However, such posts deals with audio files, and I'd like to know if it would be possible to play at least system sounds, and if notifications delivered to the watch could play a system sound like notifications in iPhone and iPad can. I don't find anything related to sounds neither in Apple Watch Human Interface Guidelines, nor in Apple Watch Programming Guide.

Thanks

It's not possible to play any audio by using the WatchKit API.
