RE: Alsa muet et OSS Ok ?
Merci beaucoup,
'amixer set Master unmute' a résolu mon problème...
Serais ce un bug de alsamixer ?
A l'origine, amixer me renvoyais ceci :

On voit que le volume est bien fixé à 100% via alsamixer mais reste [off] !
'amixer set Master unmute' passe ce champ à [on] et là, magie, j'obtiens du
son !
Est ce une erreur de manip de ma part ?
Merci en tout cas pour l'info !

Bonjour,
Chez moi, je dois utiliser amixer.
Je ne me souviens plus de la commande exacte, mais ca doit donner quelque
chose
du genre :
amixer set Master 80% (on monte le volume à 80%)
amixer set Master unmute
C'est tout ce dont je dispose comme piste
