Hi,
I just got the 4670RW and am wondering whether the device can passthrough Atmos sound via a receiver that's capable of decoding the same? I have a lot of videos and Atmos demos on a USB and am pondering whether I should haul in my friend's Atmos receiver to check if the passthrough works or not. I thought it would be a lot simpler to ask it here. Please reply.

If you are referring to an Atmos track from a ripped Blu Ray, the answer is no. BD discs use Dolby TrueHD, which is a lossless audio codec. Roku devices do not support any lossless codec, either from Dolby or DTS.
What Roku devices do support is the lossy version of Atmos available from Dolby Digital Plus, which is used by many of the online streaming services. This is the Atmos you get from Vudu, Amazon, Netflix and others. Although I don't think the Netflix channel for Roku devices supports Atmos yet.
If you want a device that supports the lossless audio codecs (TrueHD, DTS Master Audio) and/or the lossless audio with height (TrueHD/Atmos or DTS:X), then the best device is probably the Nvidia Shield. Using a player such as Kodi you get resolution and framerate matching, lossless audio support, captions for all sorts of sources, etc.
This guy @atc98092 would know.

Thanks for the help. Rather than writing a kong whining message, I'd summarize my response in this word...
D-OH!
