Do Samsung TV's not send 5.1 signals?

Well I'm trialing Atmos 4.1.2 and it sounds amazing, same does Dolby Surround.

The issue is, this is only via PC, on the TV, I can't seem to get 5.1 from any apps like Now TV, BBC iPlayer, Netflix or Amazon Prime. Under sound settings it does seem to specify bitstream or PCM, and then under the second option there is PCM and some dolby digital options that are grayed out.

This is on NU7400 TV.

Amp is TX NR686 Onkyo

Any ideas?

Is the TV connected via optical or HDMI to your amp?

HDMI ARC

It's working now, the amp auto switched from DD to Stereo depending on the channel, you can tell it switched as well due to a red icon on the amp but also the amp makes a loud double click for some reason. Must have been a glitch with the TV as I disabled ARC, enabled surround via optical and then moved back to ARC and removed optical and magically it works.

Well I have Atmos set up on the PC. This was the apps on the TV, turns out it was just a glitch and optical then back to HDMI sorted it.
