What code is executed when headphones are disconnected?
In most systems if not all, ACPI can handle this event. To test that:
- Run
acpi_listen
Unplug & replug headphones, example output: (mic/ears share in same jack on my laptop)
jack/headphone HEADPHONE unplug jack/microphone MICROPHONE unplug jack/headphone HEADPHONE plug jack/microphone MICROPHONE plug
Put
your-script.sh
in/etc/acpi/
Add an event trigger file for your script in
/etc/acpi/events/
event=jack/headphone HEADPHONE unplug action=/etc/acpi/your-script.sh
Check the other files there to learn from.
You may need to restart
acpid
service to reload changed rules in/etc/acpi/events/
sudo service acpid restart
Reference: man acpid
