It's probably worth mentioning that the permissions for sound and
video devices are now managed by ConsoleKit instead of the older
consolehelper.  ConsoleKit uses acl's instead of mucking with the
standard unix perms.  So you want to check the acl's of your devices
using the getfacl command.  As an example, you should see something
like this for /dev/dsp:

$ getfacl /dev/dsp 
getfacl: Removing leading '/' from absolute path names
# file: dev/dsp
# owner: root
# group: root
user::rw-
user:gdm:rw-
user:tmz:rw-
group::rw-
mask::rw-
other::---

Additionally, the ck-list-sessions command is very useful to determine
whether ConsoleKit considers your session to the active session.  If
it doesn't, it won't add you to the acl list for sound, video, and
other devices that it manages.

Finally, one bug that could be the cause of this is:
https://bugzilla.redhat.com/show_bug.cgi?id=380031

Another possibility, if you're using updates-testing, is the
pilot-link-0.12.2-9 update (as suggested in bz#411321).
