The pulseaudio executable fails which is also logged in my user.log. Another way to find out is e.g. to use the command
pulseaudio --dump-modules
to list the PA's modules. This gives the following initial output:
I: caps.c: Limited capabilities successfully to CAP_SYS_NICE.
I: caps.c: Dropping root priviliges.

N: main.c: Called SUID root and real-time/high-priority scheduling was requested in the configuration. However, we lack the necessary priviliges:
N: main.c: We are not in group 'pulse-rt' and PolicyKit refuse to grant us priviliges. Dropping SUID again.
N: 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.
W: main.c: High-priority scheduling enabled in configuration but not allowed by policy.
W: ltdl-bind-now.c: Failed to find original dlopen loader.
The file pulseaudio has the suid-bit set but still fails so it seems that the statement "For enabling real-time scheduling please acquire the appropriate PolicyKit priviliges" is what is missing.
