it's there:

joerg at phb:~$ pulseaudio -k
joerg at phb:~$ ps uax |grep pulseaudio

I then played test.wav with paplay, here is the pulseaudio -vv output:

I: main.c: Called SUID root and real-time/high-priority scheduling was 
requested in the configuration. However, we lack the necessary priviliges:
I: main.c: We are not in group 'pulse-rt' and PolicyKit refuse to grant 
us priviliges. Dropping SUID again.
I: main.c: For enabling real-time scheduling please acquire the 
appropriate PolicyKit priviliges, or become a member of 'pulse-rt', or 
increase the RLIMIT_NICE/RLIMIT_RTPRIO resource limits for this user.
I: main.c: Note that real-time/high-priority scheduling is NOT normally 
required. If you experience crackling or other sound anomalies, consider 
one or more of the above solutions.
I: main.c: High-priority scheduling enabled in configuration but now 
allowed by policy. Disabling forcibly.
