RPI5 with NVME - GPIO Buttons Issue

Hi All,

I’ve just built a Volumio streamer based around a RPI5, everything works (Touch Screen, Peppy Meter & Rotary Encoder) with the exception of the GPIO Buttons plugin (0.8.3) it appears to install correctly however I’m not able to save any configuration settings (using GPIO pins 4,17,22,13,16) which I believe to be unused by the system/DAC (IQaudio DAC Plus). Am I doing something wrong or is there a work around to control the buttons that I’ve missed reading the forums? Any pointers greatfully receieved.
