Yes but it run on dapper... (concerning the changement of the volume) And it works changing the alsa-base, so I suppose it's not a bios problem...
A friend confirm these bugs with another chipset (his problem is not solve by using my alsa-base) Like me, he has : $ lspci | grep Audio 00:1b.0 Audio device: Intel Corporation 82801G (ICH7 Family) High Definition Audio Controller (rev 02) -- [dapper & edgy] Sound -> Chipset ADI1981B https://launchpad.net/bugs/68556 -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
