I currently have a large amount of music stored on my WD Home NAS in various formats.  I’m able to stream MP3s to Sonos but FLAC files, although visible on the Sonos app (Music Library), bring up an error stating they don’t exist.  I guess this could be down to the NAS (which is a few years old) or the device I’m using to connect to Sonos.

I also use Spotify but again, this doesn’t allow lossless audio.

If there’s no workable solution, one option I am considering is buying a Brennan B2 or B3.  I have a large CD collection so streaming from Brennan to Sonos in lossless is appealing.

However, if I take the plunge on a Brennan, I believe I would need to set that up as the designated Music Library.  So my question is - can two folders be set up within the Music Library on the Sonos app?  I don’t want to lose access to my existing NAS as that has some unique recordings (albeit on MP3) but would love the option of streaming lossless from another device.

I guess my other question is does anyone know of  a solution to play lossless from WD Home, which has limited features.

Thanks
