Whitebear, DNLA issues with Arcam AVR360

Hi I just just decided to switch to Whitebear as the dnla front end for my squeezebox as I heard its more robust then the built in one. I am pushing files direct to my amp via DNLA as I can have better control over the audio that way. I have whitebear on my Server, SB Touch, Bubble UPNP as a controller on my phone and an Arcam AVR360 amp. I am having a few issues with it not playing certain file types though via DNLA. It wont play any FLAC files that I have at all it just seems to sit there and do nothing. I can see its putting out 3 streams LPCM, FLAC and MP3, but it just seems to hang on the LPCM. My amp had no issues playing these files through the Official SB DNLA as raw FLAC or via SB Touch as digital audio. Any ideas is this Whitebear, Bubble UPNP, SBS or something else?

Also is it possible to stream the Triode spotify plugin via DNLA. It comes up when browsing the library and you can search songs but wont play.

Any help appreciated.
