What about something like:

  import os
  import sys
  if sys.platform == 'linux2':
      os.environ['SDL_AUDIODRIVER'] = 'dsp'

before you call pygame.init? That way it even works for games you
distribute to others... or better yet, and in-game config screen that
lets the user choose an sdl audiodriver, save it in the game prefs, and
use it next time they run the game.

I would say either let the user configure that option in game (through
a menu as you suggested) or leave it out completely. By putting that
in you're forcing users into using a specific sound system, a system
that might not work for them.

Options such as this should be left completely in the user's hands.
What if I want to use DMA? I'm now forced into using DSP regardless of
any environment variables that I set.
