`pygame.mixer.Sound()` throws "Unrecognized audio format" for some Vorbis file (with emoji in metadata?)

Current behavior:

As the title said, some Vorbis audio files in my game don't load.

I have tested on both Windows and Linux. It works fine on Linux, but not on Windows.

Expected behavior:

The audio files are loaded properly.

Screenshots

No screenshots.

Steps to reproduce:

I uploaded a zip file that contains some Vorbis files. Some of them work and others throw an error. These files play properly with other audio players.

sfx.zip

• hyper-activate.ogg Error
• hyper-end.ogg Error
• charge.ogg
• get-point.ogg

Maybe the emoji in the metadata is preventing pygame-ce from loading?

Hello, thanks for the bug report!

I just tested it on my Ubuntu 24.10 system, and I cannot reproduce the issue locally (on pygame-ce 2.5.3 (SDL 2.30.12, Python 3.12.7)). This issue could either be windows specific, or something specific to your setup

[damusss]

@ankith26 I'm on windows, and this is the result:

pygame-ce 2.5.2 (SDL 2.30.8, Python 3.12.5)
loaded charge correctly
loaded get-point correctly
could not load hyper-activate, Unrecognized audio format
could not load hyper-end, Unrecognized audio format

So it must be a windows specific issue

The audio files can be loaded in pygame-ce 2.4.0, but not in 2.4.1.
