Question

Samsung SmartHub videos and 5.1 sound?

by CosmicWiz / April 16, 2013 3:51 PM PDT

Hi,

It just occurred to me that since my new Samsung ES7500 TV, by design, does not output 5.1 sound on optical out, there is no way I can watch my USB/Allshare and those streaming app videos (youtube etc) in surround sound!! Please correct me if this understanding is wrong but sounds like a big rip off.

Is there a work around? What about ARC, does it output 5.1 sound?

Thanks,
YP

HD Tech,

Your response didn't answer my question. You suggested to hook-up STB directly to HT to get 5.1 that way but what about USB and Smarthub apps which are directly connected to TV? How do I get 5.1 sound out of TV to my HT for those?

Thanks,

Hi CosmicWiz,

I'm sorry if I wasn't clear: by connecting your home theater via HDMI to your TV, you can get sound back down the HDMI cable; if your home theater has ARC, then the signal will be sent back down from the TV to the home theater. You'll just need to make sure the home theater is connected via HDMI port 2 and that Anynet+ (HDMI-CEC) is turned on both devices.

HD Tech,

ARC is not necessary, it seems. Please see my reply below.

Keep in mind that there are rules about passthrough.
by R. Proffitt Forum moderator / April 17, 2013 2:27 AM PDT

I'm going to keep it short but HDMI/HDCP mandate that pass through is only standard definition or stereo when the digital stream is passed out of a device that can render video or sound. It's a stunner for those that think that such is possible and it is possible but the industry is trying to shutter the possible leak of HD content.

There is a fine exception in the rule for pass-through of OTA (over the air) content and the issue of network playback is an area I find it may or may not work at better than stereo.

It's an industry issue and not a maker decision. If a maker decides to ignore the rule, Intel has a pack of lawyers they send in.

Thanks bob. So, the question is: does HDCP mandate of no pass-through apply to SmartHub streaming, USB sources directly connected to TV also or just HDMI IN?

So I leave it to others to read and interpret. But you can test the pass-through and from what I see, SD (that's standard definition and stereo) are being passed all the time. It's the HD content where the industry gets all fouled up.

PS. Let me sum it up another way.

Don't confuse what is possible with what this industry has done to thwart what is possible.

A -> classic <- discussion is the "sports bar" situation where you want to send the same HDMI source to a few locations. What a mess.

It ain't that bad
by CosmicWiz / April 18, 2013 3:25 PM PDT

Okay, I did some stress testing of my system and this is what I found:

HDMI-IN: TV outputs only 2 channels on optical out. There is nothing in surround speakers. SPDIF out menu has only PCM option

USB/Smarthub: If video has it, TV outputs 5.1 channels on optical out. Surround speakers do have sound. SPDIF out menu has PCM and Dolby Digital option.

So, it ain't too bad I guess Happy

Help, my PC with Windows 10 won't shut down properly

Since upgrading to Windows 10 my computer won't shut down properly. I use the menu button shutdown and the screen goes blank, but the system does not fully shut down. The only way to get it to shut down is to hold the physical power button down till it shuts down. Any suggestions?
