New to the world of Raspberry Pi/ Volumio
Im currently trying to add a physical power off button to my Volumio/RPI 4 setup.
I tried a few different approaches. One of which was to add
dtoverlay=gpio-shutdown,gpio_pin=26 to config.txt
(Im trying a different pin than GPIO 3 as I need I2C for DAC/ ALLO DIGIONE)
I was able to do so, but unfortunately when I connect pin 26 to ground nothing happens.
Note for this tests I did not have the DIGIONE DAC hat connected, but I did have a GPIO extender mounted. This one here. GPIO Edge Extension SKU: EP-0121 - 52Pi Wiki
From what I can this just spits each pin.
Any thoughts as to why the shutdown feature isnt working?
