Do your XA decoding changes fix this?

[Vincent-Halver]

It does not. I double checked and it is not a regression either.

Could be related to incorrect overflow behavior when the audio peaks.

[Vincent-Halver]

After #14449 the audio still crackles.

I think I need someone to validate the correct audio on a real console.

The following audio file was extracted from the game. It appears that this is not a bug. The audio file itself appears to be encoded with audio peaking.

Closing as working as intended.

tbh and fwiw I don't see this SW softlisted in hash/cdi.xml, may be a good idea to add it and make sure to attach this issue as a btanb note.
