I understand now it was not a logical try.
Maybe I can start from the beginning if someone can respond to me.
So I am using Open Embedded daisy without X11, PulseAudio 5.0, Linux 
armv5tejl 2.6.37.6 #18 PREEMPT.

Aplay works correctly from root but not from an other user (I should do 
setup of the sound card).
 From root :
pulseaudio --system met the error shm.c: mmap() failed: Cannot allocate 
memory
pulseaudio --start or pulseaudio -D and then pacmd list-cards give 0 
card(s) available.
