      The behavior is similar on macOS, Windows and Linux.
      Switching to native system backends may cause other issues, but without
      freezing applications.

      Here is the GitHub link to my simple Python test app:
      And here are the screen recordings of my tests on macOS,
      Windows and Linux, switching from FFmpeg to native system multimedia
      backends.

      The bug is better reproducible right after the app/script (re)start, when trying to load/play an audio file while a different one is still playing.
      Thanks!
