QE55QN700A e-arc only outputs PCM

Hi all.

I have a QE55QN700A 8K TV; I have a soundbar connected to the e-arc port, HDMI 3. However when the e-arc setting is set to "auto" rather than "off", all of the apps, such as Netflix, Prime, Disney Plus and Paramount Plus only output PCM audio to the soundbar; no Dolby Digital, Digital Plus or TrueHD; it does weirdly still output Atmos. (The soundbar itself supports e-arc and has no issue with those formats from a Blu-Ray player, which is why I suspect the TV).

However when I turn e-arc off, all the apps start to output Dolby Digital and Digital Plus, and Atmos again, (which is weird because I thought e-arc was the requirement for the newer audio formats, I'd have thought turning e-arc off would mean no Digital Plus or Atmos but it seems to be the only way to get them).

Moreover, I have a Blu-Ray player which needs e-arc on, in order to passthrough Dolby TrueHD, so turning e-arc off isn't a permenant solution; as turning e-arc off prevents passthrough.

TLDR: e-arc being on shouldn't limit audio output to PCM only; e-arc on is supposed to provide better support for audio, not worse.

If you set output as PCM on TV and have ATMOS enabled that should work. Sounds counter intuitive but fixed my issue.
