The runtime plays audio two ways — a Web Audio transport (sample-accurate) and the HTMLMediaElement as a fallback — and mutes the elements when Web Audio takes over so they don't double-play. That mute gate was global: it muted every element the moment ANY Web Audio source was active (webAudio.isActive()). A track Web Audio had not claimed yet (its larger buffer decodes slower) was muted on the fallback AND not playing on Web Audio = silent, while the other tracks played. With TTS narration + BGM + SFX, the narration (largest buffer) lost the decode race and dropped out intermittently, with every file fully loaded. Make the mute per-element: an element is muted only when its own Web Audio source is live, or the user / parent-proxy force-mute is set. A track Web Audio has not claimed stays audible on the HTMLMedia fallback until the transport takes it over — which also lets narration start immediately on cold play instead of waiting for its buffer to decode. Also in this change: - Don't permanently blacklist a transient fetch failure in the Web Audio decoder (_failedSrcs was never cleared); only blacklist genuinely undecodable bytes, so a late-arriving asset (404 then available) self-heals on the next play. - Stop re-issuing play() every tick on an errored / no-source element.
