Surround Sound via ARC Samsung 55 AU8000

Hello all,

Just got the Samsung Crystal UHD AU8000. Great TV for its price. 

However, I am trying to output Dolby Digital audio to my home theatre system, a Sony HT-RT40, via the HDMI eARC port. All I get when using the TV's Netflix app is PCM audio, 2.1 channels yet I have a 5.1 setup. I have turned on the HDMI e-ARC mode under Sound expert settings to no avail. Digital output audio format is set to 'Auto.' The 'Pass-through' option is greyed out no matter what I do. I have resorted to using optical audio for surround sound but the downside to this is that I have to control volume using the speaker's remote, not the TV's. Any ideas on what I can do or am I stuck like this? Would be quite the bummer. My previous TV, a Samsung UA40J5300, did not have ARC but I could at least change volume using the TV's remote when I connected the HDMI cable to it and used optical for digital audio. 

Also, how do I get 4K HDR HEVC content to play back properly? The colours are completely messed up. 

#AU8000

Cross-brand ARC rarely works unfortunately, even within the Samsung ecosystem it depends on the age of the devices as to whether eARC works properly or not even if both say they are ARC compliant.

Oh, man. 🥺 Isn't there anything that can be tried to at least see if it can work? Quite a shame this.

Apart from a different HDMI cable just in case it has a dodgy pin for control sharing.

Thanks for the reply. 

I tried a different cable to no avail. 

It seems I'm resigned to PCM audio for the TVs apps until, hopefully, Samsung releases an update on this. I don't think it's cool. 🥲
