how to play flac on universal media server ps4

Love the product and the work the developers do. I wish I was more technical to be able to better troubleshoot this. The receiver would recognize the audio as 6 channel DTS. Many versions back, when MEncoder was an audio engine option, things worked well for these 2 channel DTS flac files. I was not even able to get them to play in slow motion. When they were 2 channel flac dts files I could not get any engine to play them correctly. If I try and use Ffmpeg to play the 2 channel DTS wav files it plays as if in slow motion and receiver only recognizes it as two channel audio not 6 as it should. Universal Media Server supports all major operating systems, with versions for Windows. It was originally based on PS3 Media Server by shagrath, in order to ensure greater stability and file-compatibility. It is capable of sharing video, audio and images between most modern devices. With my PS3 using optical connection to my SONY STR-DA777es I was only able to get correct sound out of all 6 DTS channels with current UMS by disabling the two existing audio engines and converting my 2 channel DTS flac's to 2 channel DTS wav files. Universal Media Server is a DLNA-compliant UPnP Media Server. My wav files are two channel as well with DTS encoded in them (play as 6 channels when properly sent to receiver). When correctly sent to the receiver they play as 6 channels even though they are technically two channels. Not sure if that is the right way to say It. I think the issue is that my Flac files were 2 channel with DTS encoded in them.
