Raspberry Pi 1.54inch LCD-Retropie-Audio configuration tutorial

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
(audremap18.dtbo just enable gpio18 as pwm audio pin,
This Above code will not enable gpio19 as pwm audio pin,
gpio19 have configured as key START)

After rebooting , You need enable local audio
