 Summary of the bug: Specific E-AC-3 streams with Atmos occasionally fade
 in from zero amplitude at a block boundary, producing a click. It only
 happens on the first playthrough. Rewinding to before the defect in the
 same player session makes the fault disappear. Channels higher than 0 in a
 5.1 layout are affected. The official Dolby decoder works fine. The
 streams were acquired from Apple Music.
