Looking at the SWMixer docs, you probably want

   snd = swmixer.Sound(data=tone_data)

Well, sort of. You probably need to scale your data and convert it to int16 
format. It's currently in floating point format.

When asking about why something fails, it helps a lot if you specify exactly how 
it fails and what you expected to happen. Copy-and-paste any error messages exactly.

If you need more help with SWMixer's API, I recommend asking the author. It's 
not in widespread use, so he can probably give you better and faster help than 
we can.

If you need more help with numpy, specifically, you can ask on the 
numpy-discussion mailing list. numpy *is* in widespread use, but there's a 
higher concentration of helpful numpy users over there.
