No audio from speaker from TinkerBOY 2.2

PWM audio is configured to use GPIO18 and GPIO13 by default but you can edit the following lines in the /boot/config.txt to either enable 1 or 2 audio channel(enabled by default).

Code: Select all

# 2 channel audio
dtoverlay=pwm-2chan,pin=18,func=2,pin2=13,func2=4

# 1 channel audio
dtoverlay=pwm,pin=18,func=2
