Fixed Runtime Error in _normalize_loudness on Windows Torch 2.11.0+CU128

[SundayRX]

Resolved a compatibility issue with the _normalize_loudness function on Windows (Torch 2.11.0+CU128 RTX5070TI)

Thanks for working on this compatibility fix.

Could you please share the full RuntimeError stack trace you encountered on Windows with Torch 2.11.0+CU128? That would help confirm whether the failure happens in torchaudio.load(), loudness calculation, saving, or another part of _normalize_loudness.

One concern with the current implementation is the broad except Exception around torchaudio.load(). It may also catch unrelated issues such as corrupted files, permission errors, or unsupported formats, then silently fall back to soundfile, which can make real problems harder to diagnose. It would be safer to catch the specific torchaudio/backend compatibility error if possible, or at least preserve/log the original exception context when falling back.

Thanks again!
