Can someone tell me how to play a specific sound file in the Music Library of my Sonos system on a specific Sonos. I'm trying to use the ChangeStationByUri(stationName, streamingUrl) function but no success yet. The command is being transferred to the Sonos player when I put the link to the file (\\NAS-....) instead of stationName (and leave streamingURL blank) but my Sonos controller tells me "Unable to locate ...". Also tried putting the audio file in my Sonos favorites and calling the favorite in bOS but no luck so far.
