GPIO Audio Module-Raspbian-Audio configuration tutorial

If your Module is GPIO18
Download audremap18.dtbo to your pi
sudo cp audremap18.dtbo /boot/overlays/
sudo nano /boot/config.txt
Add this code
dtoverlay=audremap18,pins_18_19

If your Module is GPIO19
Download audremap19.dtbo to your pi
sudo cp audremap19.dtbo /boot/overlays/
sudo nano /boot/config.txt
Add this code
dtoverlay=audremap19,pins_18_19

If your Module is GPIO18&GPIO19
sudo nano /boot/config.txt
Add this code
dtoverlay=audremap,pins_18_19

Then you need reboot
sudo reboot
After rebooting , You need enable local audio

sudo raspi-config Select System Options -> Audio -> 'headphone'

Then reboot again use sudo reboot

Set audio voice max and play any music then you will hear sound
