Need help with Transcode

[lwxian]

Hi Support Team,
I have been trying to setup my Synology NAS to enable transcode for playing back flac and dsf files but I could not get it to work. Here are the codes of the profile I use.

contentDir = /volume1/Music/
indexTags = Genre, AlbumArtist, Album
mergeFolderAlbums = false
serverOptions = indexArtwork=auto
startupScan = true
tagOptions = Album.sortTags={AlbumArtist}
stream.transcode = flac:wav24/176
stream.transcode = dsf:wav24/176

Please guide me on what is wrong with the above profile or I am missing out some codes... is it stream.options? or flow control etc?
Thanks!
Leong
