I previously tried connecting my amazon fire stick directly to the unit via HDMI and their was no sound when dolby digital plus was used. Today I have tried listening to queens speach which is dolby atmos encoded via my sky Q using dolby digital plus via HDMI and no sound.
I have checked the manual and it clearly states that dolby digital plus is support and I looked around and their is suggestion that the HDMI drivers need to be updated for the unit.
Any advice. my device has the last firmware install 1023.1, which is dated June 2015.
