Upnp Gapless on Uniti Atom

Hi I was wondering if its possible to have gapless playback via uPnP on the Atom. I have bubble upnp server setup and have set the Atom as a openhome device and enabled gapless playback but it did not work.  Should it work with the Naim app itself (not a fan of it so trying to use an alternative) or has anybody else got this working with gapless and if so what are they using. I have a QNAP nas which runs Squeezbox with upnp enabled and BubbleUpnp.
