Audio Devices (Marantz SR-7013 - HDMI)
I am not able to change the Channel Layout settings in the Device Setting window. It is locked on 2.0
Please advise on how this can be modified, or why the setting is locked.
I assume you are HDMI connected into some input on the Marantz. Kindly share which input. Does your Roon audio setup have a selection something like NVIDIA High Definition Audio (WASAPI)? Or is that what you are already connected to with this problem? JCR
