You'd better read some history before speaking.That is funny! I wouldn't trust Edison because he would say that for the money. And in 1911 there was no sound. They didn't even have color.
The first RECORDED sound was in the late 1850's. Two decades later (that would the 1870's for mathematically challenged) Bell made the first telephone call and Edison introduced the first phonograph recording.
And of course.....there was 'sound' long before.
And color? Have you ever had the experience of looking at a tin type photo before it was exposed to too much uv light sources that bleached them out?
