DDJ RZ with a USB Sound Card

Pulse

I am on Windows 11, I have Rekorbox 7.0.2, I have a DDJ RZ.

I have a Radial USB-Pro Stereo DI for Laptops that I use in my studio and recently upgraded my studio monitors and really like the sound coming out of the USB Sound Card

I am thinking of taking the sound card it on my next Gig.

Here is my question, In Rekordbox I select Audio Radial USB-Pro - Works perfectly.

I get no sound from Headphones???? Not sure what else the external Sound Card Kills?

Thanks for any help....
