bonjour,

j'ai fait un essai infructueux :

aplay -D hw:1,0 /usr/share/sounds/alsa/Front_Center.wav
Lecture WAVE '/usr/share/sounds/alsa/Front_Center.wav' : Signed 16 bit Little Endian, Fréquence 48000 Hz, Mono
aplay: set_params:1345: Nombre de canaux non disponible

et je n'ai toujours pas de sortie audio

merci
slt
bernard
