Raymond - 06-19-06 14:57
----------------------------------------------------------------------
There is no segmentation fault when
aplay -Ddefault:1 atmos30.wav
aplay -Ddefault:1 beat2.wav
aplay -Dplughw:1 *.wav
Since aplay use snd_pcm_drain() between different files ,the segmentation
fault seem related to "Warning: format is changed to U8" and dmix

The shmem record was changed due to this fix, hence you need to close once
