So, this is interesting: the client requested 30ms (which is needlessly
low, but that's another question), but the server ended up providing
only 444 ms! That is incredibly high and points to the fact that PA
probably ran into quite a few dropouts before this, presumably due to
incorrect timing or suchlike, and hence bumped up the minimal latency
all the time, and bumped down the sleeping time, hence eincreasing the
CPU load. Almost certainly your audio driver is at fault here.

Check syslog for any comments about that.
