Public bug reported: Problem occurs shortly after pulse-audio is first used after login. I'm able to reproduce this consistently by trying to play sound through Firefox right after login, although speech-dispatcher eventually exits and audio returns to normal.
Only occurs whilst `speech-dispatcher` is visible in `pavucontrol`, killing `speech-dispatcher` solves the problem for me. I was able to grab the exact command and arguments being run from `ps`: `/usr/bin/speech-dispatcher --spawn --communication-method unix_socket --socket-path /run/user/1000/speech-dispatcher/speechd.sock` By running it I'm able to reliably trigger the crackling audio.
