Just purchased QN95A (with One Connect Box) and noticed the following behaviour:
When using HDMI-CEC functionality, TV is not sending Dolby Digital audio via either HDMI-ARC or Optical. It is simply dead quiet. PCM audio format works fine. Sometimes there is loud click when audio formats are switched before audio goes silent - like digital noise for a fraction of a second.
When HDMI-CEC is disabled, then I get both PCM and Dolby Digital audio formats via optical cable, HDMI cable in that case is not available for audio at all. The issue exists when HDMI-CEC is enabled on both AVR and TV (This is required to enable swicthing and volume control using TV remote).
Receiver is Yamaha RX-V473 (it suports HDMI-CEC, HDMI-ARC and audio formats ie. PCM, DD, DD+). Everything works without any issues with 2 year old Q80R.
Already tried: 6 various HDMI cables, resets, cold reboots, disconnecting power, etc. TV is on the latest firmware.
There are many posts regarding HDMI-CEC and ARC issues with Samsung TV but I didn't find anything about losing only Dolby Digital while PCM would still be working.
Obviously using only PCM audio format or disabling HDMI-CEC on brand new TV is not an option to me.
Any advice welcome.

Hello, I have the same problem with my old Yamaha receiver and Samsung QN95A. Any new about this issue?

Mam dokładnie ten sam problem. 5.1 przestało działać. Zauważyłem, że stało się to po aktualizacji. Też mam kino LG. Pozostaje czekać aż to naprawią.

Jaką masz wersję oprogramowania ??

Any replies to this? I have the roughly same issue with a Samsung AU8000 plus a Sony HT-RT40 home theatre system. Cannot output DD via HDMI from the TV's apps like Netflix (passthrough option is greyed out in the expert sound settings). Got around this by using an Optical connection and was able to use the smart remote as a universal remote to at least be able to control the home theatre's volume - no way to control power. I am on version 2001 of the TV's software if that helps.

Mam tą samą wersję oprogramowania. Po aktualizacji tv właśnie do tej wersji dźwięk wrócił do normy. Na poprzedniej wersji oprogramowania był problem.

I have the same software version. After updating the TV to this version, the sound returned to normal. There was a problem with the previous version of the software.
