Pygame causes ALSA underruns due to small period size on XO-4

Physics and Maze use a lot of cpu (50% aprox) without doing anything.
The log show a continue stream of:
ALSA lib pcm.c:7339:(snd_pcm_recover) underrun occurred.
The activities don't use sound at all.
Just to compare, in xo-1 use 39% cpu, and don't show the error msg, and in xo-1.5 use 20% cpu.
Using the activity Maze on xo-4 for a while, I saw random crashes. (The easier way to trigger it was rotate the screen a few times, I am not sure if is related or not)
