Read the trailer's sound pass.

The last sound pass laid on the trailer and whether one can be laid now: soundPass (null when none was asked for) with its status (queued, laying, laid, failed), auto (laid by itself after a story film's first master), cueIds (the cues it placed on the timeline's sound-effect lane, listed with their loudness on the sound map), placed, notLaid (each designed sound it left out, with why), remade (cues made again because their file came out too quiet, clipped or gappy) and error; canLay and blocked (no_master before the cut is rendered, in_progress while a pass is being laid); and sentence, the one line every surface says. Read-only. Scope: story:read.
