missing sox extension when using augmentations v2.3.1

[chrizzlemadizzle]

When trying to use --augment compress or --augment gain in training these errors pop up:
OSError: libsox.so: cannot open shared object file: No such file or directory
RuntimeError: apply_effects_tensor requires sox extension which is not available.
It doesn't happen when using --augment mute
I'm on v2.3.1 using --config v3 and --config wasserstein

yes, to use gain and compress you have to install sox beforehand (torchaudio usds the sox backend). Check on the internet ;)
