Could you post a screen shot of the Roon signal path … when configured this way and this stuttering occurs.
I’m wondering what value Roon’s processing speed is.
I’ll tag @support to follow this up with you… In order for Roon’s team to better assist you, please provide a brief description of your current setup using this link as a guide.
Make sure to describe your network configuration/topology, including any networking hardware currently in use, so they can have a clear understanding of how your devices are communicating.
