Running latest update of 2.6 on MicroRendu (with Roon Ready version 1.1.30), but can’t get an option to use DSP volume control on Roon.
I’ve set the volume control to “hardware” (also tried “software”) on the MR, rebooted the device, turned off and then on the DAC, etc., but I only ever have the option for “fixed” volume on Roon.
I’ve never tried to use DSP volume control before, so can’t say if this is new behavior.
Once this has been set you should be able to use DSP volume as seen in the screenshots below. Note that the DSP volume takes place on the Rendu itself, not Roon, so the Device Control setting is what you’ll want to use here.
My understanding of your documentation is that the device option is where the DAC has a volume control option, and the endpoint is passing on that information. But this one doesn’t.
I wasn’t aware of the rendu products having anything either.
