qjackctl

I really like the Qjackctl Graph, and while there are several patchbays available i would like to stick with Qjackctl.
I start Qjackctl hidden in tray, but i would like to have the the Graph window to open whenever i start Qjackctl, is that possible?
Thank you.

I just installed qJackCtl (and jack) on my Macbook running Catalina 10.15.7. I plugged in my Scarlett Focusrite Solo (MIDI-USB interface) and also started Jamulus. My goal is to be able to connect a 3rd party audio source like iRealPro or Chrome (Youtube) to Jamulus (the audio sink) so that my online band partners and I can play along to a backing track, drum track, or just listen to a recording without leaving the Jamulus session. I'm having trouble getting started and I can't find any docs to help me on a Mac. Most of the docs cover Linux with Alsa.

Hi,

We are new to Jack, and are trying to understand what the RT % number means? Can anybody explain it to me? My colleague and I are using qjackctl with jacktrip, and notice that we have differing numbers here, but aren't sure what to make of it.

Thanks!

Scarlett 2i2 shows up in jack but not in Reaper, or in ARDOUR. No recording at all.

Here is what I get when I type ./configure at the command prompt;

I'm running the latest version of qjackctl built from source on ubuntu 20.04.

I installed the Alsa-API library and if I select alsa in qjackctl's driver options, the outputs (including my USB interface) appear fine.

My goal is to use portaudio to stream audio from a custom software to dedicated speakers via a USB interface. If I select portaudio (or any driver other than 'alsa', I just get 'default' as option and the server does not start.

What am I doing wrong?

Thanks.

Hello,

is there a way to launch a session automaticaly ?

that would be just awesome

thanks

I'm trying to configure qjackctl to use a Blue Snowball USB microphone as the input device and the system sound for output (with headphones).
When I click on Setup and then Advanced Parameters, how do I select the appropriate options?

Hello,

while I managed to build qjackctl from the git repo, I notice the ALSA button was grayed out in the patch bay

I uninstalled it and reinstalled the default raspbian qjacklctl package (which has the ALSA button not grayed out)

I was wondering is there any reason why it is so ?

I did not notice any advantage to use that git version, apart bezier curves used as connections in the patchbay, so I dont mind using the old one

regards

Hello,

I was wondering why my ALSA device was not listed in qjackctl

I can clearly see it in alsa, but it does not appear as I try to add it in the patch bay
