NUC8ixBEH HDMI Sound issue - only showing Stereo

[DavidNUC]

I am not able to get Dolby Digital/5.1 sound options on my NUC - just recognises Stereo only

NUC & TV Details:-

Make/Model Intel NUC8i5BEH

TV Make/Model - Samsung UE43MU6100 - firmware up to date.

NUC BIOS - 0088 30/3/2021

Motherboard - NUC8BEB Version J72692-307

Memory - 16GB

OS - Windows 10 Pro (64-bit) Version - 2009(10.0.19043)

Processor - Intel Core i5-8259U CPU @ 2.30Ghz

Graphics - Intel iris Plus graphics 655 - Driver Intel V27.20.100.8681

Audio - Intel Display Audio - Driver - Intel intcDaud.sys V10.27.0.9 25/02/2020

Realtek High Definition Audio - Driver - Realtek RTKVHD64.sys V6.0.8981.1 30/06/2020

I have run Intel Driver & Support Assistant - it comes back as being up to date.

Nuc8i5BEH is connected to Samsung TV using HDMI cable (input), the TV sounds (output) settings is connected to Sonos Playbar using Spdif, and is set to Dolby Digital (on TV). However HDMI/Sounds setting on NUC only recognises Stereo (2) speakers and not 5.1 - that option is greyed out.  So I am not getting Dolby Digital from the TV when using NUC - Just PCM.
When TV is using Amazon/Netflix directly (SmartTV) I do get Dolby 5.1 on Sonos Speakers - just not from NUC, which I use it for Plex to playback Movies/Series Library.

So I have tried the following articles/troubleshooter on Intel website:-
HDMI Audio Doesn't Work on Intel® NUC - Went through all the Options and are all OK - Samsung TV is set as default.
Audio or Display Problems Related to HDMI on Intel® NUCs That Use LS-PCON (HDMI firmware update)- Updated but no differences.
Also tried EDID Editor - but to no avail - Configure Surround Sound on an NUC

So I am now stuck and need Intel Support

Any advice please?
