You don't really need to fix this. The message means that pulseaudio
will not run with high priority but that is probably not a problem. 

Most probably you have to include the pulse-rt group in your user groups
(ie: the groups the user that you login as has).

OK, thanks, Fernando.  I'll try adding myself to the 'pulse' and 'pulse-rt' groups, just for fun.
