Volumio 3 Issues?
Just a quick question, I have a nice Volumio box with a 14 inch display and I wanted to put a led on the front panel that shows activity… Ive seen where you can add a led to a pi with out a hat but no instructions on adding one with a hat… can this be done?. I have a Rasberry PI 3b and a hifiberry dac hat pro . Thanks in advance.

if I recall correctly, t=you need to add the following to the /boot/userconfig.txt.
dtparam=act_led_gpio=xx

where xx is the GPIO where you have connected to the LED.

I’m not sure is this would work woth a dac hat as it used pins from the gpio .
