I have been streaming my CD collection FLAC files in 7.2.4 for over a year now. Use an older router with a USB attached 8TB drive. Connect my Pioneer Elite SC97 via ethernet to the router (hardwired.)
I have all of my living room theater equipment connected to the router. So that I can control each piece of equipment. The router has NO internet access connected. I use the Pioneer AV5 app to access and control the media server functions. The app is great provides all the details about each song, album, album art and artist and can play ALL songs shuffled within the entire CD collection.
It’s been nice to enjoy my CD collection again. Listening to artist and songs I have not heard in a long time.
