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.
Can you give some more details about what you're seeing? Specifically, what CPU / audio hardware you have, if you're using any non-defauly PA settings, what your buffer size / sample rate is in JACK, what applications you're running that interface with the sound servers (e.g. pavucontrol, carla). I have a fairly complex setup that routes sounds from PA to JACK and back to PA, and the PA server only consumes ~5% of one CPU core (on an i7-6600U laptop). Running pavucontrol can cause that number to rise, though, since each sound source / sink has an audio stream to drive the VU meter. --Sean
