My problem is that I’m not sure if Jack is running or not.
Jack seems to be starting OK - QJackctl and Ubuntu Studio Controls both state that it’s running but when I open Guitarix a message states that Jack is not running and Rakarrack crashes on opening.
I’m using a Windows 7 & era laptop now running Linux Mint 20.1 Ulyssa with a low latency kernel.
Any ideas?

Re: Jack says it's running but Apps say it isn't.
Looks like jack is running, but rakarrak is crashing, for some other reason.
What is accurate message Guitarix says?

Guitarix refuses to open a message says: Jack is not running.
Hydrogen works.
Thanks.

Re: Jack says it's running but Apps say it isn't.
You don't need them both.Studiohead wrote:... QJackctl and Ubuntu Studio Controls ...
That means JACK was already running when you opened QjackCtl.Wed May 12 09:37:40 2021: New client 'qjackctl' with PID 4024
That means you're using jackdbus which may start JACK when you log in. JACK is definitely started. Why doesn't Guitarix recognise it? To work out why try having the simplest setup possible.09:37:40.938 D-BUS: Service is available (org.jackaudio.service aka jackdbus).

Re: Jack says it's running but Apps say it isn't.
I uninstalled and reinstalled Guitarix and Rakarrack and now they work.
Prior to this they’d refused to work yet Jack was running, this happened after Jack refused to start, I managed to get it to start again but the above 2 x apps seemed to become uncoupled from Jack after the re-start.
