Hello,

thank for your response and corrections of the topic "minimal_playback.c " from http://equalarea.com/paul/alsa-audio.html There are good tutorials too : http://home.roadrunner.com/~jgglatt/tech/linuxapi.htm http://jan.newmarch.name/LinuxSound/Sampled/Alsa/

On the raspberry, with ArchLinux, the jan.newmarch version and aplay command make the wav jumps for the beginning and sometimes in the middle of the wav music.

Do you think it comes from the raspberry’s « bcm2835 ALSA » audio chipset or the arm processor efficiency or other things ?

Thank You for your help
