[arch-general] PA over JACK: excessive work?

[riveravaldez]

Hi, I'm using PulseAudio over JACK and noticed in htop that while not
doing nothing PA works much more than when idle alone, is this
normal/right?

This is what I do:
Close everything that uses audio. Start JACK through qjackctl.
$ pulseaudio --kill
$ pulseaudio --start
(So, PA now works as some kind of bridge redirecting audio through JACK.)
$ pactl load-module module-jack-sink
$ pactl load-module module-jack-source
(So I have general sink/source ports to make connections.)

But then I check htop and PA is working all the time. Is this normal?
Am I doing something wrong?

Thanks a lot in advance.
