Cannot load audio from pathlib.Path

🐛 Describe the bug

Running the following:

import torchaudio
from pathlib import Path

test_audio_path = Path('test.wav')
torchaudio.load(test_audio_path)

Produces the following error:

Traceback (most recent call last):
  File "<stdin>", line 1, in <module>
  File "/Users/pinea/miniconda3/envs/EveryVoice/lib/python3.10/site-packages/torchaudio/_backend/utils.py", line 203, in load

Declaration: torchaudio::sox_io_load_audio_file(str _0, int? _1, int? _2, bool? _3, bool? _4, str? _5) -> (Tensor _0, int _1)
Cast error details: Unable to cast Python instance of type <class 'pathlib.PosixPath'> to C++ type '?' (#define PYBIND11_DETAILED_ERROR_MESSAGES or compile in debug mode for details)

But my understanding from the torchaudio.load type signature is that a pathlib.Path should be accepted here.
