This is the problem. Due to some reason PA starts to each a lot of CPU
time in which case PA's load limiter will become active and ask it to
commit suicide. 

Or actually this is just a symptom of a problem. What the actual
problem might be difficult to tell. PA starts to spin in some busy
loop for some reason. That might be a driver problem, might be a PA
problem, might be simply a client that asks for very low latency (and
hence high CPU load).

Could you please to the following:

1) Add a system load monitor applet to your panel, so that you can monitor if
your CPU is idle or not.

2) Terminate PA in a terminal:

$ pulseaudio -k

3) In the same terminal start PA with debbuging output on and the load limiter off:

$ pulseaudio -vvvvv -no-cpu-limit

4) Try to reproduce the issue, watch the load monitor applet. Does CPU
load go up to 100% for longer time? if so, please open another
terminal, type "pacmd ls" and paste the output somwhere.

Is this an USB audio device? Driver? Could you please dump the start
of the PA log output somewhere (i.e. the part that shows the
initialization phase)?

Which PA evrsion is this?
