I just set up my new Roku 3. It is connected via HDMI to my HD621 which goes into an 861v8. Unfortunately I can't get any sound when I select the Dolby Digital Plus 5.1 option in Netflix (or Vudu.) I can get sound with stereo. (My Roku settings are set to 5.1 surround.) Is DD+ not supported yet by Meridian? I have tried selecting all of the DSPs on the 861 but no sound. I'm guessing this is going to take a firmware upgrade?

Thanks,
John
