          First you need to kill the existing pulseaudio process, start the jack_control process and re-start the pulseaudio process.



          Please use the below commands:



          pulseaudio --kill

          jack_control start

          jack_control exit

          pulseaudio --start

            Try using pasuspender with qjackctl. Like this:



            pasuspender qjackctl



            It should "pause" pulseaudio while qjackctl runs and "respawn" pulseaudio when qjackctl is terminated.

                            Try using pasuspender with qjackctl. Like this:



                            pasuspender qjackctl



                            It should "pause" pulseaudio while qjackctl runs and "respawn" pulseaudio when qjackctl is terminated.
