Bonjour, je viens de me rendre compte que j’ai un petit soucis au niveau du son sur mon PC portable, lorsque je branche un casque dans la prise jack, cela ne coupe pas le son des enceinte du portable =/ , cependant il y a bien du son dans le casque.
Avez vous une idée pour résoudre ce problème ?
Pour info:
machine : Acer Aspire 7740g
kernel : 2.6.32-5-686-bigmem
module son : apparemment HDA Intel avec ALSA (je n’ai pas installé pulseaudio)
