#11578: Waveform discontinuity in decoded E-AC-3

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.
