The [This device is not compatible with Roon 2.0] message on your laptop - you have a Compatibility Mode for an earlier version of Windows set on the roon.exe program - it needs to be turned OFF. See this post:
It’s ifi’s job to integrate Roon’s streaming technology directly into the firmware of their device. If you are talking about the Pro iDSD Signature DAC/Amp, then the product page does not mention it being Roon Ready, which means that ifi have not done the work to add support for the RAAT streaming protocol into the product.
Talk to ifi about adding Roon Ready support to the product - not Roon Labs.
Since the Support team will not be able to help you on this issue, I’ve moved your post from the Support category of the forum and put it into the iFi category. Thanks for your understanding.
