PS3 Slim (HEN) - Cutscene dialogue missing in multiple games

Hi everyone,

I'm having a really strange issue with my PS3 Slim running HEN and I'm hoping someone has seen this before.

Symptoms:

- Gameplay audio works perfectly (gunshots, explosions, ambient sounds, music, NPC greetings, etc.).

- Only cutscene dialogue is completely silent.

- Subtitles still appear normally.

- This happens in multiple games, including:

- GTA V

- Red Dead Redemption

Things I've already tried:

- Resetting the date and time.

- Reconfiguring audio output settings.

- Restarting the console.

Since it's affecting more than one game, I'm starting to think it's a console configuration or audio issue rather than a bad game dump.

Has anyone experienced this before or know what could be causing it?

Any help would be appreciated. Thanks!
