Rasberry pi 4b

[fred9000]

i built something with a rasberry pi 4b alone with moode audio and add a start button to gpio with pin 5 and 6 and now with soft shutdown i can start it with the push button ( i modify the txt file also ) but now i add a fifopi q7 II with hdmipi pro II and want to use my same button but i asume that i have to use different gpio pin number , is somebody here that have the same setup and share what number of gpio pin i can use ofr if i can do it , for the modification of the file , i can do it
thanks
