Description
This problem was detected in olpc xo-1.0 using Dextrose image from Uruguay (dxo-uy-1.0).
After executing in python:
import pygame pygame.init()
the proccess pulseaudio shows 10% cpu usage.
Changing the SDL audio driver is a workaround:
import os os.environ['SDL_AUDIODRIVER'] = 'alsa' import pygame pygame.init()

I used the workaround in an activity I'm working on.
It would be nice to fix the problem for the next Dextrose release, I don't know if it's a SDL problem or a pulseaudio problem, but I guess is one of these.
In the older image (802c) that problem didn't occur.

iirc this was tested on an activity that pablo is working on, seems like a general issue.

To what exact activity you added pygame workaround?
In any case would be useful to change Component field to that exact activity (and create similar bugs for the all pygame activities). Because these are different people who maintains all these activities (unfortunately Sugar doesn't handle activity deps in some cases people bundle pygame to theirs activities).
