[Linux-bruxelles] pas de son sous Gutsy, mais es-ce ALSA ou le kernel?

Hello,

un ami (novice) n'a pas trop attendu pour se jeter à l'eau: 
Feisty->Gutsy et hops! plus de son.

Mais apparement plus de carte détectée (chip snd_hda_intel normalement) et
plus de mixer dont on peut remonter le potentiomètre etc.

S'il reboote parcontre via grub avec le précédent kernel, (Feisty), là il 
a du son, et
dans son lsmod je vois aussi les lignes snd snd_hda_intel snd_hda_codecs 
etc.

D'où mon étonnement de lire qu'il y aurait un blème d'Alsa, alors qu'ici il
a du son dès qu'il redémarre Gutsy avec l'ancien kernel.

Qq'un a-t-il une lumière/+ svp l'url de launchpad.net consacrée à ce problème
(pas un site trop convivial avec lynx, sorry).

Voici aussi en guise de preuve des details:
