Dear Lenard, I did it. But the "mixer" comands don't also need to be
changed for it to play? Thanks,

Hi Sarah,

There are two audio drivers pygame.mixer can use on Windows. I believe
the default is "waveout". Try setting the SDL_AUDIOMIXER environment
variable to "dsound" to use the directX. This can be done within Python
by adding these two lines to the top of the file:

import os
os.environ['SDL_AUDIODRIVER'] = "dsound"


This will work for Windows, but not Linux. So add add some conditional
code to only set SDL_AUDIODRIVER when the program is running on Windows.

Hope this helps,

Lenard Lindstrom
