I have my amp connected trough USB to the silent Angel Rhein and it is saying connected to the Core. But when i swith of my Amp the connection is lost and HDA intel PCH Analog appears in connected to the Core. This is very annoying because this means i have to reboot the silent Angel Rhein every time. I unplugged/ plugged the USB Cable to see if my Amp appears when i boot it up but that did not help.
