Thanks all.

I sorted out my problem.
I tried numerous times to update the AMD driver for the Graphics card and it kept failing.
The AMD website kept saying it was the wrong file for my OS.
Anyway, I went and bought a cheap graphics card online. While waiting for it to arrive, I tried one last time to update the driver.
And, suddenly it worked. Always kena like this...buy new and then the old one will decide to work.
So, with the update, the card works well now.
I get Dolby TrueHD and DTS Master now on my AV.

Also, I installed Plex Media Server into my PC based NAS and use Plex Home Theatre for my HTPC.
Also there's mobile apps for iOS and Android too if you wanna pay for it. Haven't tried it though.

Thanks again.
