I have a little function that plays back numpy arrays using PyAudio. I think PyAudio is pretty platform independent (but it takes a bit of installing). My code is not perfect, but it is simple and works ok. Want it?

Sorry, I should have been more specific.  I am really looking for a way to play audio as part of a script.  Your link would certainly work for playing back sound in an interactive manner in a notebook. However, it is not really useful as part general-purpose script or function,  or when control of the playback is needed. Thank you, though, that is certainly very useful in many situations.
