No...  you should be added to the acl list associated to the device if
you are the physical console user as per the authorization policy
managed by PolicyKit.  This it how it works from at least F10 onward.
Mucking around with file ownership directly is "old think." The system
scripts associated with pam use to do that on user login and
logout...but has been replaced with the more flexible solution
involving acls that PolicyKit based hardware access authorization
makes use of.


for example on the F10 system I'm on right now:
ls -la /dev/snd/seq
crw-rw----+ 1 root root 116, 3 2009-06-17 07:07 /dev/snd/seq


getfacl /dev/dsp
# file: dev/snd/seq
# owner: root
# group: root
user::rw-
user:myuser:rw-
group::rw-
mask::rw-
other::---

I do not own the file in the traditional Unix permissions sense. But I
am listed in the acl list with read write access.  If your user is not
in the acl list, something misfired in the area of the PolicyKit based
authorization handling.
