The library function winsound.PlaySound takes a sound parameter. One of the valid arguments is a path to a WAV filename.

Since Python 3.4, paths can be cleanly represented with PathLib.Path instances.

However, if you pass a Path instance to PlaySound, it responds with:

   TypeError: 'sound' must be str or None, not 'WindowsPath'

This can be quickly fixed in the caller by passing str(the_path_instance) instead, but it would be cleaner if PlaySound accepted Python's preferred method of representing paths.
