I think we should have a list of issues with the HLE plugin posted somewhere, I'll list the issues I'm aware of:
- BGM music or any music that uses the AFC decoder stops looping after the first or second time playing. PCM16 looping may also be buggy, but the game affected seem to use the AFC decoder and are affected by the same issue or similar issues. Games affected are Super Mario Galaxy, Super Mario Galaxy 2, ZTP, Mario Kart Double Dash, other games.
- Volume issues or missing music (not sure), affects some Zelda Ucode games, as of right now I only observed Wario World with this issue. Other games may have this issue as well.
- Magic meter audio is wrong in Zelda Windwaker, I think it uses saw wave or square wave audio.
- Missing/wrong samples, missing music such as BGM music, incorrect music tone or music notes with music in most AX/ADCPM games. Affects all Resident Evil games except Wii version of Remake and Zero (I think), Starfox Adventures: Dinosaur Planet, Tales of Symphonia, other games. In the Gamecube version of Resident Evil 4, cutscene audio goes silent only moments into the cutscene and also the issues with BGM stopping like other games.
If the bugs that are causing the above issues are tackled then all affected games will likely see an improvement.
