The decoder cached on a note was keyed on nothing, so a note reused for a different streamed sample carried on decoding the previous track. Audible as the wrong custom music: the sequence and soundfont the audio editor reports are correct, only the samples reaching the mixer are not. Reproduced on the game-start cutscene chain with a streamed music pack in 4 of 6 runs; 0 of 6 after.

Fixes #5684.
aOPUSdecImplcaches itsOggOpusFileon the note and keys it on nothing, so a note reused for a different streamed sample carries on decoding the track the previous note was playing.Audio_NoteDisablefrees the handle, butAudio_NoteInitForLayercan run on a note that still owns one.This is why the audio editor looks right: sequence and soundfont selection are correct, only the samples reaching the mixer are not. #6736 fixed the selection half of the issue; this is the rest.
