Public bug reported:
While playing back any sounds, a certain crackling sound (static) will
play with a fixed delay of the sound being played. The amount and volume
of the static will depend on the sound/music that is being played, and
this only starts occurring after a somewhat long time (30 minutes or
more). What is interesting to see is that while playing back music from
Spotify (Snap) the static will only start after a second or so, but when
playing YouTube videos on Firefox, it will be immediate and output that
static while the video is playing.
I've added two sound recordings, one while playing back a song from
Spotify and the other while playing a song from YouTube. This issue goes
away when restarting the PulseAudio service, but it comes back after a
random amount of time.
