UR22C Audio Set-up Headphones Only

Good Afternoon all,
Is it possible to install and use the UR22C with computer and headphones only - no monitors or MIDI units.

I’m a beginner and thought I would start there. When looking through the Audio files of instruments to audition for use, headphone plugged into front of UR22, and various volume settings, no sound comes through the headphones from the audio files but the tutorials play through them without a problem.
I couldn’t find any directions in the manuals to setup using only headphones.

Appreciate any hints thankyou.


Have you downloaded and installed the DspFX mix software?
