Moving PWM to GPIO pins on the Raspberry Pi

# We are adding these to config.txt on the SD card
# From Windows/etc, just edit the file in the root directory of the first partition, from the Pi itself edit /boot/config.txt

# Uncomment the settings you would like.
# Make sure you are using a modern Raspberry Pi bootloader or this will do nothing.
# If it does not seem to work, flash a fresh SD card with Raspbian and try it.

# If you want stereo sound from GPIO pins 18 and 13
#dtoverlay=pwm-2chan,pin=18,func=2,pin2=13,func2=4

# If you want mono sound from GPIO pin 18 only
#dtoverlay=pwm,pin=18,func=2

# You can use any of these GPIO pins for the above:
# pin=18,func=2 (PWM0)
# pin=13,func=4 (PWM1)
# pin=19,func=5 (PWM1)

# Enable sigma delta modulation (considered experimental as explained in my video)
#audio_pwm_mode=2

# If you are not using sigma delta, use this to make it sound cleaner at times:
#disable_audio_dither=1
