A playing sampler voice whose waveform still accepts blocks (CONTINUE)
reported only INUSE|PLAYING after it had played every queued block, so
a title that waits for EMPTY before it reuses the voice never did.
PPSA18391 (engine: Clickteam Fusion) reads state_flags & 0x22 != 2 from
sceNgs2VoiceGetState as the end of a sound; each of its sound effects
played once and never again.
The voice now also reports EMPTY (0x20) in that state and keeps
playing, so blocks added later still play. A waveform that was closed
without CONTINUE does not report it.
AddWaveformBlocks rejects a null data pointer before reaching the silence
path, so TestSilenceBlock aborted and its dataless rejection passed for the
wrong reason.
A waveform block that declares samples with no data threw as not
fitting them. PPSA04867 adds such a block with flags 0x11 (data_size 0,
num_samples 16385) and terminates the process on the throw, followed by
a fully specified block under the same flags, which takes the ordinary
path. Accept flag 0x10, named SILENCE here: a dataless block under it
renders num_samples frames of silence and finishes like a complete
block, reporting its bytes through decoded_data_size. A dataless block
without the flag keeps throwing. No public reference names the flag;
the assumption is recorded in TechnicalDebt.

A 16-bit PCM block whose num_samples exceed its data starts a stream, and waveform blocks with flag 0x2 append more data to it. The voice outputs silence while it has played all appended data and CONTINUE is set, and ends at num_samples or when CONTINUE is cleared.
