Audition 2020 cut off the output signal from my RME UFX

Just uopdated to Auditino 2020 I have got the following problem:

When listening to anything else than microphones on my sound card RME UFX the Audition cuts off the signal to my loudspeakers on the board while at the same time tjere is no input signal to be recorded.

I have loaded my normal presets on the sound board.

What have I done to Audition?

ThankS!
