the ALSA jack plugin has poor latency too. anything that has to

intermediate between a "push" model API (where the app gets to decide

when and how much data to read/write) and a "pull" mode (where

something other than the app makes those decisions) has to have enough

buffering to deal with the app's intentional and unintentional

behaviour. it probably isn't as latency inducing as pulse's default,

but its not a replacement for using JACK directly.

if you distro didn't set this up and you want it to work, i suggest

you switch distros to one that does. you may get advice from this or

other lists about how to do this, but configuring PulseAudio to be the

default audio I/O system is a challenge most for distro packagers, not

users. if you then add in the fact that you actually want pulse to

talk to JACK ... now you're out of even distro packaging territory.
what you are trying to do is just not recommended practice. JACK

targets pro-audio/music creation workflows. it is not intended to be a

desktop sound server.
