Exact: j'ai express�ment mis dsp, audio et sequencer sur 666, et rien
n'y fais, c donc pas un pb de permission; mais si c un pb de conf,
comment cela se fait-il que sur TOUS mes autres pcs le son a tj tout de

C'est un chipset on board, je me souviens que Knoppix lui avait charg�
le ad1848, j'ai donc fait pareil; il semble l'avoir pris, j'ai mis �a
dans /etc/modules et vois ci-apr�s mon lsmod + strace de saytime en
tant que root (car peu importe, root ou user, le pb persiste).
