Public bug reported: Crackling sound only when audio is played during a few minutes after startup, then normal sound.
During ubuntu-bug test, the first set of sounds played fine, crackling began immediately after the end of the first set, continued before I started the second set, and lasted during the first seconds of the second set, then became normal again during the remaining of the second set and after it.
