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

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

Go to retropie menu

Select -> AUDIO -> HEADPHONE

Then reboot again use sudo reboot

Set audio voice max

Press key START enter retropie MAIN MENU

select SOUND SETTING
->SYSTEM VOLUME 100

->OMX PLAYER AUDIO DEVICE -> LOCAL

Go back press key B，
Then enter SOUND SETTING ->SYSTEM VOLUME again
You will see it is 97 or 77,You need set it 100 again|
After all setting， the VOLUME will became ok
