Environment Details
ubuntu24.04 / cuda128 / torchaudio==2.9.0
Steps to Reproduce
Running Fish Audio with TorchAudio 2.9.0 fails due to removal of torchaudio.list_audio_backends(), which is still called in fish-agent/tools/api.py.
The function was deprecated in 2.8 and fully removed in 2.9 (released Oct 2025).
The project’s pyproject.toml declares:
cu128 = [
"torch>=2.5.1",
"torchaudio",
]
so torchaudio is unpinned, allowing 2.9+ to install automatically and break compatibility.
Reproduction Steps
Create and activate a clean conda environment:
conda create -n fish python=3.11
conda activate fish
Install Fish Audio in editable mode with the CUDA 12.8 extras:
pip install -e .[cu128]
Run the Fish Audio agent or any module initializing audio I/O.
Observe the crash:
AttributeError: module 'torchaudio' has no attribute 'list_audio_backends'
