At the time rtkit-daemon is/was running as the gdm user since no user
was logged in using the gui.
So perhaps I can fix this in /etc/security/limits.conf?
Hmm.
Putting gdm user in pulse-rt group does fix the rtkit-daemon messages
but not the pulseaudio error.

I will seek help for this elsewhere as it is not so on topic here.

Thanks for the patch!
