I have an issue with the audio on SkyQ as follows:
Setup is Q90R TV with Q70R soundbar.
SkyQ plugged into soundbar and ARC port on soundbar to ARC port on OneConnect box.
Sound works fine with SkyQ digital audio output set to Normal, ie PCM.
When SkyQ digital audio output is set to Dolby Digital or Dolby Digital +, the sound is fine on non-HD channels, but on HD channels it is appalling. You can hardly hear people speak and their voice is very tinny.
