Great that Sonos and Plex have come together! Finally!
It appears that Plex does transcode my DSD files (I use .dsf as it supports ID3v2 tags) and it plays them via my Plex Android app. I don't get the transcoding and playback, however, to Sonos. My high bitrate FLAC files do work. Is this something to come? Ideally, Plex should convert all FLAC, DSD, PCM, etc to simple CD standard for Sonos.
Also, please let Plex respect embedded tags in .dsf files. This includes the folder/cover art as well. Can it also look at the "folder.jpg" too in a directory and grab that? My stuff is tagged completely and Plex seems to ignore it.
