After my computer resume,
I have to
pkill jack and start ubuntustudio controls and click on the button "start or restart jack".
I am on my way to create a resume script (how to execute a command after resume from suspend?)
[Unit] Description=Fix jack audio after resume from suspend After=suspend.target [Service] User=trif Type=oneshot ExecStart=?????????????????????? [Install] WantedBy=suspend.target
But at ExecStart, I'm a bit stuck. what to write?
pkill jack && what ?
How to restart jack with the same parameters of ubuntustudio-controls? How to view the jack parameters line that ubuntustudio-controls launch maybe? Or, is there a hidden parameter to ubuntustudio-controls to launch jack when it launch?
Jack simply doesn't support suspend/resume as it's simply not designed for it. You need to stop Jack via ubuntustudio-controls before putting your machine into a suspend state.
