Kinetophone (partially found early sound recordings; 1894-1912)
From The Lost Media Wiki
Status: Lost
The Kinetophone, developed By Thomas Edison, was a combination of the Kinetoscope and the phonograph to create the first recordings with sound.
Though many samples have been found, only two of them have the audio found and repaired, due to the rarity of the wax cylinders used to record the sound on. You can find the footage below.
