why are the inodes in /dev/snd only crw-rw----  and in /dev/sound crw-rw-rw-? (i don't really understand the concept having a /dev/snd AND a /dev/sound ... or is it simply legacy-reasons to keep older software working?)

Re: udev: /dev/snd <-> /dev/sound

my dirs are the same permission-wise... you may have an extra 6 in your /etc/udev/permissions.d/udev.permissions...

I think that /dev/sound is legacy (if I rmmod snd-pcm-oss this /dev/sound is empty).

thanx for confirming that i'm not crazy or having paranoia ;-)

yes, indeed i have

I think that /dev/sound is legacy (if I rmmod snd-pcm-oss this /dev/sound is empty).

oh ... didn't think at that  ... exactly! if oss-legacy is removed, the duplica /dev/sound disappears - and now the world is a little bit more logical to me

thanx
