Hi,
no chance, I tried many times configurations and nothing. I have always the
same case, once I can record without hearing the guitar I am playing into
ardour. I only listen to it after the recording, otherwise I with
pactl load-module
module-loopback, the delay kills..
Any tuto for installing jack, ardour and recording.
Please help.
Regards to all.

Hi again,
When activating this module for hearing what I am producing live, pactl
load-module module-loopback, that the 2 seconds delay comes. Otherwise
and
without this module I am unable to hear the sound
nor to record...
Is there any advice/ tuto for recording and listening in the same time
the
hole jam (my guitar with things I created...)
You have started JACK on the "default" ALSA device, which on your
system is PulseAudio.
Please tell JACK to use a "raw" or "hardware" device such as
"hw:0",
though you will have to stop PulseAudio to make this work.
For reference, JACK should almost NEVER be started using any
devicename other than hw:N

google will find many.
but we've already established that you have a problem with pulse
audio. you should NOT use pulse audio and JACK together unless you
really, really know what you are doing. your problems are because you
are making JACK route audio via PulseAudio. PulseAudio is not a low
latency system, and feels entirely at ease creating seconds' worth of
delay.
many of us either remove pulseaudio, or never install it, or disable
it, or use 2 audio interfaces ("soundcards") and leave to do its thing
wth the el cheapo builtin one.

Pulse can do low latency but it's main goal is to provide seamless desktop
audio for normal audio users and mobile devices.
If you want to do low latency recording/audio production then you should
use jack directly.
If you don't want to uninstall PA then use jack2 and all is dealt with
gracefully.
Cheers.

jack2 by itself doesn't do this. it will happen if the combination of
jack2, dbus, pulseaudio are all set up correctly.
you don't need jack2 for this either, there are quite elegant schemes
to get pulse out of the way no matter which version of JACK is used.
the key point is that they all require some system configuration (or
checking system configuration) and i didn't want to suggest that to
someone who is clearly a newcomer to this environment. except that
then i did anyway :(
Pulse can do low latency but it's main goal is to

audio for normal audio users and mobile devices.
actually, Pulse can't do low latency by any reasonable definition of
that term :)

pactl ? Are using PA for this ?
Disable PA, make Jack use the ALSA hardware device,
and your problem should be solved.

Ok friends, thanks for your support. I am new with ardour, I always used
widows for my recordings with Cubase SX, and since it was always a unique
sound card I didn't have issues.
I'll test all your suggestions and feed you back.
Thanks again,

i don't know how much you actually know about windows audio, but an
analogy from that world would go something like this:
"you're supposed to use Cubase with ASIO, but you've configured ASIO
to talk to a virtual audio device that is actually
routing via the kernel mixer, and is thus adding hundreds or even
thousands of msecs of latency to the signal"
and yes, you could actually do this on windows, but it would take some
effort. the problem on many linux distributions right now is that
they've setup this type of configuration for you, even though its
totally broken for your purposes.
