Owner

Some sounds never play.

Who it hits most: scripted music players. They chain many short sound clips (llPreloadSound, llPlaySound / llTriggerSound, llSetSoundQueueing), and individual clips, or the rest of the song, go silent.
Where it came from: this is old behaviour inherited from Alchemy/LL, not a recent regression.

The #883 memory audit (3987d194db) found that the audio decode manager wedged after failed decodes:

A failed decode was put back as "in flight" and never finished.
Each failure therefore held one of the decode slots for the rest of the session.
Once enough bad assets had been seen, no new sound ever decoded again.

That is fixed, but it may not be the whole story.

Scope

Find every way a requested sound can fail to play: fetch, decode, buffer, source, queueing or timing.
Retry failures with a bound: retry a failed fetch or decode a few times before marking the asset bad.
Never let a bad or slow asset block other sounds.
Make clip chaining for music players reliable.
Log why a sound didn't play.
