Bonjour,

Je suis sur Debian Testing, et depuis que je suis pass=E9 en noyau
2.6.15(avec udev) le son ne marche plus (ni Alsa, ni OSS, ni ESD).

J'ai bien cherch=E9 sur les archives de la liste ou sur Google, mais rien d=
e
bien convaincant...

J'ai un chip int=E9gr=E9 VIA mais aussi une carte TV :

J'ai bien les devices /dev/snd/... ainsi que /dev/dsp et /dev/mixer.
