How to correctly connect a guitar to Linux Mint?

Question

linux

Hello!
Has anyone tried connecting a Linux Mint electric guitar?
I found Guitarix software, which allows you to add various gadgets to the guitar, but it requires jackd to work correctly. Installed jackd on the computer and the server starts.
The problem is:
- you need to kill the pulseaudio process. Accordingly, I type in the terminal
pulseaudio --kill
But! After a few seconds, it starts up again.
At the beginning there was this problem:

“Jack Server is not running or cannot be started”

We chop off pulsaudio, start jack_control (for some reason, pulseaudio starts again)

pulseaudio --kill
jack_control start

We return to the original state:

jack_control exit
pulseaudio --start

Also used this source for setup - https://askubuntu.com/questions/237793/guitarix-am...

sudo dpkg-reconfigure -p high jackd2
sudo usermod -a -G audio username
su username -c guitarix

In general, now the guitar does not sound.
PS On windows, this is usually done like this: - asio driver + (amplitube || guitar pro).

Answer 1

And it will start because it is a service.
Stop service
sudo systemctl stop pulseaudio
