I haven't had that problem -p 32 r 48000 starts on my D66 with no
problems. 32 samples is pushing it for this system though, just changing
workspace is enough to give an xrun sometimes. bumping it up to 64 seems
to be enough. I am using a 10year old P4 at 2.4Ghz. In general, I have
found pulse seems to take twice the cpu that jackdbus does at the same
latency. (according to top)

I have found that unloading the module-jackdbus-detect module while
recording is just as effective. Pulse uses very little resources with the
PA-jack bridge unloaded. It can be reloaded when finished recording or
just pulseaudio -k

I have a script that does this... as well as a few other things (turn off
cron and other services I don't need, set CPU governor to a steady state,
etc)
