How can I send a .mp3 to play through my mic?

[ejected]

you can play the mp3 directly from the python script.
The easiest way to do this is with pygame mixer which is use like:

from pygame import mixer

def play_mp3(mp3filename):
    mixer.init()
    mixer.music.load(mp3filename)
    mixer.music.play()

That's not what I'm trying to do.....

I need to change the output device to something other then my Windows default one.

Something like this: So that I can change the playback device
