Volumio 3 Issues
The way that i have to do it, is,
every time when i try a different GPIO pin for the sensor module to see if it works, first i shut down the Pi, connect the ir module and connect the volumio to the browser and select the ir remote profile which is JustBoom and select the GPIO #. I did that, reboot Volumio and them try the JustBoom remote and nothing. I have to keep reinstalling volumio to the pi4 in order to get the GPIO configuration and try another gpio pin and reboot and nothing. this is the worse headache ever.
