XDJ RX - Not working as USB soundcard (Windows 10)

Hi,

My XDJ-RX is not working as USB soundcard in Windows 10. 

I downloaded and installed Rekordbox. It asked for the audio setup and executed it for the XDJ-RX.

The XDJ device is visible in the sound settings:

It is turned on ('Use this device' is Dutch for 'Use this device'):

The levels are set to 100:

and it is set to 2 channel, 44.1K, 16 bit stereo:

However, there is no input line visible in the sound settings (tab Recording devices) and I guess there should be one for the Microphone, am I right?

The device manager shows this:

and 

On the XDJ it tried different settings for mixer mode (XDJ and MIDI mode). Of course I checked whether the master level is not set to 0 and such.

When it didn't work after the Rekordbox-setup, I downloaded and installed the drivers (XDJRX1000exe.zip) from the download page. Without any result.

Please help me with this issue. Thank you!

With kind regards,

Jarno
