Sound is crackling when not playing anything. It stops crackling when I play something. - Log out again and relog (no need to be fast). This time only one process is up but the sound is still crackling. Killing the process fixes it. - On subsequent logouts+logins, the issue does not seem to be reproducible. I have to reboot. Another clue: After a fresh boot, the first time I log out I can see from a TTY that 3 pulseaudio processes are now running. If I wait some seconds, they all eventually die and I can login without sound issue. Subsequent logouts won't spawn those 3 processes. If however I follow the above receipe and log back in fast enough, an additional process is spawned (which is normal) but the 3 processes remain.
