Presonus Firestudio soundcard seen by ROON, but no sound return to soundcard,

Maybe you use the wrong channels?

Motu 828x mute with Roon

Roon is usually just using the first 8 channels. So do you hear sound when you connect something compatible to the analog 1-2 channel outputs? Note: Roon is not a mixer software. You may need something like a software that provides a virtual sound card (compatible/seen by Roon) and properly setup with/for your Motu multi-channel audio interface to be able to use it as you wish to. You can also find older threads about that on the forum: Search results for 'multi channel interface' - Roon Labs C…

What happens if you configure and use System Output in Roon instead of the external interface directly (assumes that the interface is configured as standard output device for your computer)?
