Research direction
Start with the provided setup.py bdist_wheel reproduction in the nvidia/cuda:11.3.1-cudnn8-devel-ubuntu20.04 environment and inspect the linked build log. Then trace the import warnings through torchaudio/_extension.py and torchaudio/backend/utils.py; done means the built wheel imports without the C++ extension and audio-backend warnings.
