Readme.md

sudo mkdir /etc/acpi/actions

sudo nano /etc/acpi/actions/jack.sh

sudo chmod +x /etc/acpi/actions/jack.sh

#!/bin/bash
runuser -l $(id -nu 1000) -c 'killall pulseaudio'

sudo nano /etc/acpi/events/jack

event=jack/*
action=/etc/acpi/actions/jack.sh

or to be more specific:

event=jack[ /]line
action=/etc/acpi/actions/jack.sh

sudo /etc/init.d/acpid reload

another option

systemctl --user disable --now pipewire.socket
systemctl --user disable --now pipewire.service
systemctl --user restart pulseaudio.service
and adding this script in /lib/systemd/system-sleep/99_restart_sound :

sudo chmod +x /lib/systemd/system-sleep/99_restart_sound

This may also fix sound problems: sudo alsactl restore
