Hmmm. Do you actually even hear two sounds? The channel.play method 
shouldn't wait for the sound to finish, so I would expect only the latter 
chan.play to have any audible effect. You can wait for the sound to 
finish using for example (not tested):

from pygame.locals import *
pygame.event.set_allowed(None)
pygame.event.set_allowed(USEREVENT)
chan.set_endevent(USEREVENT)
chan.set_volume(1.0, 0.0)
chan.play(snd)
pygame.event.wait()
chan.set_volume(0.0, 1.0)
chan.play(snd)
pygame.event.wait()


And the way I read the docs, you pass (1.0, 0.0) and (0.0, 1.0) to 
set_volume in order to get sound from only one channel.
