Does DirecTV Stream support Dolby Digital 5.1 Sound

I am an audiophile with what I consider very sophisticated components.

I have good knowledge of connections and various cables.

I have had no luck trying to reach someone at DirecTV Stream that is qualified to assist me.

Before agreeing to a 2 yr contract (which is no longer required) I emphasized the importance of DD 5.1 and was told it is available and supported which was FLASE :(

Does Direct TV Stream support 5.1 Dolby Digital Surround Sound and if so,

what is the correct way to connect the AT&T Receiver (C71KW-400) using the OPTICAL OUT connection?

Using the Optical Out connection does the HDMI CABLE stay connected or does it get disconnected?

Does using the Optical Out Audio Output supercede the HDMI Audio if I leave the HDMI CABLE connected?

If I cannot obtain DD 5.1 sound and am going to change to a different provider.

I would greatly appreciated if someone can take the time to respond,

Thank you,

JDaily

Hello @JDaily thanks for reaching out to us. 

The DIRECTV STREAM device supports Dolby Digital 5.1. We don't want to see you go, and we want to share with you the DIRECTV STREAM device user manual. The connections you make will depend on the audio device you connect to your DIRECTV STREAM box. 

Remember that we'll always be here for you in case you need further assistance.

Which flavor of DD are you looking for?  S/PDIF (optical TOSLINK) can in theory carry basic DD 5.1, but not the more advanced variants, and it isn’t required to carry more than stereo.  

The DirecTV Stream service supports DD 5.1 (for content that offers it) on various devices, and that includes the DTV-branded streamer. However, I don’t know if that device supports DD 5.1 over the optical link or just over HDMI.  (I don’t use one in a surround sound environment.)  

Since you apparently have been a subscriber for a good while (contracts basically went away almost 2 years ago) is your problem with DD on the device new, or hadn’t you tried that configuration until now?

Is there a reason you can’t try running the HDMI through your AV receiver?

Yes, the C71K supports DD5.1 audio via both its HDMI and Optical Digital outputs. I simply connected my C71K HDMI output to my Denon AV Surround Receiver and get DD5.1 audio just fine.

But have you also tried the optical link without HDMI to the receiver and without ARC?  It’s clear DD works over HDMI, but if you have both, HDMI may take precedence.

Yes, it works with both HDMI and optical digital, even if HDMI isn't connected.

That’s odd - I’m not familiar with any AV receivers (which would seem the only type that would support DD 5.1 decode or have amps for that many channels) that don’t support HDMI or video switching.  But OK. 

Before anything else - I assume you’ve checked the settings. But if not, under Settings>System>Audio, you can select either Stereo or Surround - make sure it’s set to Surround.

WRT your other questions:

You obviously always need to use the HDMI port on the DTV device to get video to your TV, and there is no setting to control where audio goes to (and I don’t think there’s any way for the device to know something is plugged into the S/PDIF port), so the device must output audio to both the S/PDIF and the HDMI. That means there can’t be any superseding at the device. And if your receiver doesn’t support HDMI, there can’t be any superseding in the receiver.   So if the device is set to surround and the content you are watching has DD 5.1 sound (not all does), then per @litzdog911 ’s comment, there should be DD 5.1 arriving at your receiver.
