Roon on MacPro Laptop Played Through Headphone

I can set up Roon to play fine though a LG monitor attached to my laptop, but when I try to listen with headphones, I’m getting a lot of loud clicking with the music. What have I set up wrong?

More info about your hardware, setup and settigs would be useful.

Do you use DSP?

Is it Ok when you select system default and switch to the headphones in macOS (top right of screen)?

Thanks for your answer. We were about to leave for France so I was short of time and just bought a Dragonfly DAC/amplifier. It works fine with Roon.

I do play DSP, but was not using it when the popping occured. In any case, It’s all working now.

Again, thanks for taking the time to answer.
