IR Remote Control with Lirc

[IT-Andy52]

Sorry
still another (maybe stupid) question from an absolute beginner:

I have an HiFiBerry DAC as Hat on my Pi. If I include a IR-Sensor, how do I this technically - in my view all pins are occupied - is there some kind of "in-the middle-connector" ?? The number of the pins mentioned the IR is attached to are these generally not used by soundcard Hats or do I have to find that out?

Thanks for help
