Hi all - first time poster.
I'm hoping for clarification about the audio output capabilities of the TV. I'm trying to play Atmos content from Vudu (the Atmos Amaze "Movie") via the smart hub. I am connected to a Marantz 7009 receiver. I have tried both optical and HDMI and can't get anything better than Dolby Digital.
I just chatted with Samsung support and they say the HDMI 4 output (the one that supports ARC) only outputs PCM, and the Optical outputs up to 5.1. I am trying to understand therefore that the TV will never be able to output atmos via smarthub.
FWIW I've tried connecting my Roku and it will play Atmos just fine.
Any help would be most appreciated. Below is the chat transcript.
Albert W: The TV certainly outputs 5.1 if the app support the codec.
Visitor: OK - what about atmos?
Albert W: The TV supports Dolby MS11.
Visitor: ok I'm trying to understand if that will allow atmos to be passed through
Albert W: The Dolby® MS11 Multistream Decoder provides television with a single-package technology solution for decoding all premium audio formats, including Dolby Digital Plus, Dolby Digital, HE AAC with Dolby metadata, and all HE AAC/AAC bitstreams.
Visitor: ok, I see that
Visitor: what audio out setting should I have on for best results then? I'm hooked up the ARC HDMI port on the TV. I assumed that would output the best sound to the receiver
Albert W: Even though HDMI is capable of carrying a 5.1 audio signal because of HDCP (High Density-Bandwidth Content Protection) the TV cannot bypass decoded 5.1 audio content from the HDMI input to the optical output. Because of this 5.1 audio output is not available with the HDMI input.
Visitor: Ok - i get that, but what about the output from apps then?
Albert W: It should support.
Albert W: Only available with apps that carry a 5.1 audio track.
Visitor: via HDMI
Visitor: right - almost everything carries 5.1
Visitor: netflix, amazon, vudu all do. vudu carries 7.1
Visitor: I thought optical couldn't carry anything higher than 5.1 but I may be wrong
Albert W: HDMI only supports PCM audio.
Albert W: Where as Digital optical supports up to 5.1.
Visitor: you mean HDMI from the tv, right?
Albert W: Yes, HDMI from the TV.
Visitor: OK. I think that makes sense then. If you can only go up to 5.1 out of the digital optical and the HDMI only supports PCM, then that explains why I can't get atmos
Visitor: same reason I can't get 7.1
Visitor: is that correct?
Albert W: Yes, that seems to be the issue, for testing purpose, you could perform a factory reset of the TV as well.
