I just checked my system log when loading the jack-sink module and noticed
the same thing:
pulseaudio[30057]: [pulseaudio] module-jack-sink.c: JACK error >Cannot use
real-time scheduling (RR/15)(1: Operation not permitted)<
pulseaudio[30057]: [pulseaudio] module-jack-sink.c: JACK error
>JackClient::AcquireSelfRealTime error

It doesn't seem to cause any problems, I  just played a couple of youtube
videos with no underruns.
