Before I buy something else that doesn't do what I want I need to ask some questions.
If I understand from what I've read in the docs. The Digi+ I/O will act as a streamer from an iPhone and Apple Music to my DAC.
Now I also have a CD transport. I again think from what I've read I can connect it to Digi+ I/O either electrical or optical input.
Lastly I have a NAS. I'm using PLEX DLNA. Is GMrender or something similar available in the HiFiberry OS?
Last question. How do I go about switching sources? Will the remote do that?
