Recorded sound had existed in the experimental work of scientists long before the time of practical playback, as can be seen in this brief collection of early recordings made between 1806 and 1886. A hand written date can be seen inscribed in most of these images. Disclaimer : I made an error upon identifying the medical researcher I called Angelo Russo, his name is actually Angelo Mosso (1846 - 1910)
