Hi there, archiving the game keeps your save file and profile settings on the console, which is why redownloading loaded the same configuration back in.
Try these steps to see if it helps:
- Check in-game sound settings: Go to Options > Sound from the main menu and check if the dialogue/spoken language was changed to Spanish separately from your subtitles.
- Check Player 2's profile: If you're playing co-op, check whether Player 2's Switch profile or account region is set to Spanish, as the game can sometimes inherit settings from the second player.
- Refresh Switch language settings: On your console, go to System Settings > System > Language. Switch temporarily between English (US) and English (UK), let the console restart, and launch the game again to force it to reload the language pack.
If none of those work, check for corrupted audio files before doing a full reinstall:
Go to System Settings > Data Management > Manage Software > It Takes Two > Check for Corrupt Data. If it finds an issue, it will prompt you to redownload only the damaged files. If the check comes back clean and the audio is still stuck, a full delete (Delete Software, not Archive) and fresh reinstall would be the next best step.
Let us know if that helps.
