Hey @Marcin_Batkowski — Thanks for reaching out!
We moved your post into it’s own thread so we can better track and assist you here.
First, may I kindly ask that 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 we can have a clear understanding of how your devices are communicating.
So we can better understand what you’re experiencing here, can you please describe exactly what you’re seeing when you are using the iGalvanic device with Roon?
Thanks!
Dylan
