Cannot get the extra 25 GPIO pins to work with AUDIO+

I can’t get the extra 25 GPIO pins to work on the AUDIO+ HAT. They seem to not output anything changes in voltage when I access them with Python. I’m talking about the small loose ridge of 25 GPIO pins that are shipped seperately. right now it’s resting in the holes and i’m curious is perhaps they need to be soldered or something?

Hello yes the 1 row 25 pins header need to be soldered
