Are you logged in on the graphical console?

The way this normally works is that the login display manager will change
ownership of the audio devices to whoever is logged in on the console,
using logindevperm(5) via di_devperm_login() and di_devperm_logout() -
there's a patch 11-login-device-permissions.patch for lightdm that
actually does this for you.
