Hi. I'm considering an X9 for use with Roon and roPieee as the bridge. I'm interested in understanding if the X9 supports HID control over USB. If it does, it should be possible to set up the Roon zone so that Roon can control the volume of the X9 through the USB connection from the roPieee box to the X9. Is it possible to find out if the X9 does support this HID-based control over USB? Thanks!
