Hi @Adam_Casey ----- Thank you for the report and sharing your feedback with us. The insight is always appreciated and my sincerest apologies for the delayed response here.
Moving forward, to help aide in our evaluation of this behavior may I very kindly ask you to please provide us with a brief but accurate description of your current setup using this link as a guide. Additionally, from the RME website I see the card has the following:
“Three MADI I/Os - two optical and one coaxial are accompanied by one AES/EBU I/O and one analog monitoring output.”
Have you tried testing with all of the available interfaces to confirm if the experience is any different in Roon?
Additionally, how are things functioning with the MADI fx card in play, outside of Roon? Just curious from a data standpoint.
PS: I would also give @Rugby’s suggestion a go if you have not already
