To suspend the service, stopping PulseAudio do: systemctl --user stop pulseaudio.socket systemctl --user stop pulseaudio.service To start it again, you can use: systemctl --user start pulseaudio.socket systemctl --user start pulseaudio.service Is PulseAudio running? ps ax|grep -i pulseIf yes 40871 ?
