When the module is loaded the acl gets installed.

The snd_seq module is not loaded, but udev created the character file. If you would run manually "modprobe snd_seq" it will fix the acl on /dev/snd/seq. This doesn't seem like udev issue, but more like initrd issue. I mean I think it should be included in the initrd image. I'm not taking out udev from the problem, just considering other options :) -- Configure bugmail: https://bugzilla.novell.com/userprefs.cgi?tab=email ------- You are receiving this mail because: ------- You are on the CC list for the bug.

I've even checked Fedora and seems to have the same issue with /dev/mixer /dev/dsp and /dev/snd/seq like we do. Adding those lines in 50-sound.conf will fix the issue, or at least it should, it does fix it on openSUSE:12.2 :) If we don't wanna use 50-sound.conf, we can use a default one, something like 10-alsa-default.conf and add this to alsa package.
