Description of Issue

I am trying to understand why I only see DSD128 as my max sample rate. Any advice on why this is happening and settings I can change to get DSD 256 and DSD512 as options as well.

I think I found the reason… the Lumin iPhone app allows volume control from within the Roon interface. This is really convenient but if it is enabled the DSD sample rate is capped at 128 for some reason. If I disable this volume control in the Lumin app I can select all of the DSD settings.

I will have to do some test to see if setting DSD to 256 or 512 is worth the loss of this volume slider that is accessible within the Roon app and not have to use a separate remote for volume.
