No Dolby Digital 5.1 from X1 Box for X1 Apps
My old Comcast box had a TOS output that I had connected to my Receiver in order to get 5.1 Dolby Digital.
My new X1 box "Comcast X1 XG1v4-A 4K Primary TV Box" Does not have a TOS output, only HDMI out. I
connect the HDMI out to my TV's HDMI input. My new TV does not "pass" Dolby Digital out of it's TOS
So I do not get 5.1 to my Receiver... my Receiver is not ARC, so I cannot use HDMI Audio to it. So I
purchased an HDMI Audio Extractor, and connected it between my X1 Box and my TV. [X1 Box: HDMI Out]
>>> "In" HDMI Audio Extractor "Out" >>> [to HDMI on TV], AND Extractor has a TOS output that I connect to
Now here is the strange part: Watching a TV channel from the X1 Box, my Receiver shows "Dolby Digital"
and I get 5.1 audio from my Receiver.
BUT, If I run ANY application built into the X1 Box... Netflix, Prime, Disney Hulu, Vudu, I do not get ANY
audio to the Receiver.
It cannot be my extractor, since it works fine on a TV channel.
Going in the Audio settings on my X1 Box: I only have 2 choices for "HDMI Audio Output"
1 = "Auto Detect Dolby Digital" - Which if I select - I get NO Audio for a TV channel or an X1 App.
2 = "Expert Setting Dolby Digital" - Which does give me Audio (5.1 DD), But only for a TV Channel... Nothing
from the same X1 Box if I choose an App from the box!
Calling Comcast is no help, they just have you power cycle the X1 Box, or they send the X1 Box a reset,
which has NO effect. And the Comcast Call Center people have no technical knowledge beyond that.
If only Comcast had a 4K Box with a TOS output, but they do not.
