How to configure GPIO pin 18 and pin 19 as PWM audio function on RPi 5B?
I tried adding the configuration "dtoverlay=audremap,pins_18_19" to the nano /boot/firmware/config.txt file on RPi 5B, but after rebooting and selecting "System Options -> S2 Audio" in sudo raspi-config, I didn't see any new audio devices. I also didn't see any new audio devices in the GUI settings.
Later, I tried using a different configuration in the file: "dtoverlay=pwm-2chan,pin=18,pin2=19,func=2,func2=2". I followed the same steps, but still didn't see any new devices.
I tried disabling and enabling the KMS configuration, as well as switching between X11 and Wayfire in raspi-config, but still couldn't find any new audio devices.
