Specify which audio device to use on remote wndows VM with KRDC

Hello,
Currently on X11 with Plasma 5.27. I have a setup with 2 Microphones and 3 sound outputs for various reasons. What I would like to do is to use a specific set of mic/headphones with VMs that I access via KRDC.

What troubles me is that I have setup the application “ALSA plugin [xrdpp]” to use my headphones as the output device. But it’s not working! I have to change the output from the Devices:

In order to overcome this problem, I wonder if it’s possible to define the audio devices directly in the KRDC profile.

Can I?
