A few basics (just to be sure):

- Check /etc/security/limits.conf, where you should give
  RT and memlock privileges to the audio group.
- Check if you are in the audio group.

If these are OK, the usual suspects are obese desktops like
Gnome and KDE, their zillions of dependencies and daemons,
and their security configurations using polkit and consolekit.
If that's the case I can't help, I'm not using those.
