Thanks all. It’s probably a fair assumption that you may not be able to install just anything on a Roon Nucleus since it’s a Roon device. However, I also have a NAS that I use for photography; it’s hardwired to the network just as the Bartok is.
But installing and managing a server to make audio files accessible may be beyond my IT expertise. I’m open to experimenting with this if anyone can point me to an online resource to walk me through the process, or perhaps just outline it in non-technical ways.
I could copy over my audio files and see what happens.
I have nothing against Roon. I love it and it works beautifully. But so does the Bartok. I’m open to tinkering with Mosaic and bypassing other apps since the Bartok can do that. It simplifies the chain of connected devices and apps.
