What is the oldest known Chinese audio recording? I have tried search engines and Wikipedia articles on the history of audio recording, in English and Chinese, but couldn't come closer to this.

What is the oldest known recording of anyone speaking (Mandarin) Chinese? Is it available online?
Fred Gaisberg of EMI made the first Chinese audio recordings 1903-03-18/1903-03-27 in Shanghai.
