Play sound before shutdown
In tasker is the profile "shutdown" and a task "play ringtone with the option to change it to notification"
But its not working.
I want the same like in this videos. On phone or another device.
The original is from audi
Someone else have a solution but he did not share it
He is using a Android 6.0 device... So its possible.
The media file is in mp3 format
