DVS feature not working RBDJ 4.2.2 DDJ RZX

Hi ,

When trying to calibrate the turntables I'm getting 'Error' and I cannot start the DVS feature in RBDJ.

I can play the turntable, sound coming into the controller and out to the speakers, but I cannot enable the DVS feature.

In the Preferences the DVS feature is enabled and deck 3+4 are set to phono in the output config.

Windows 10 64bit USB 3.0 16core pc 128GB RAM

Anyone, please help !
