Pygame Performance with pulseaudio

[pmoleri]

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()

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).

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.

Dextrose is not tracked here anymore.
