No sound on most TV channels Denon 4000X

And yes, since you posted the Internet is starting to explode with this issue.
I have an X4000 and have had no problems like this. (We use Dish, not Direct.)
I wonder what is unique about the OP. Is this something I should expect in the future? Is there a new generation AVR from somebody that can handle it?

I've seen some handshake issues with native format and hdmi. Try a fixed resolution and see if you get sound.
Just did that, and the lower rumble signal left the SW.
The upper end of the SW's FR was still faint as it had been, just lost the rumble.
The options were On or Off for Native.
Thanks for the reply :)

Well, my guess is DTV did a major "upgrade" without beta testing it, or very limited testing.

I've been running this setup over a year without anything like this.

I made a boring youtube video that shows the issue and the temporary or not, PCM fix.
My wife commented on how different her DVR'd show sounded now.
Trust me, if she noticed, the sound is flat as a pancake using this method…

As far as a DVR capable of handling the contradiction I'm experiencing, I'm sure there is.

That was a good demonstration. I think the issue is that the compression codec has changed. The problem is the Denon, it lacks the correct codec to adapt to this changing environment.

Check for an update here.

I have no idea who did this update, but it might have been done by the broadcasters and not Direct TV.

Unfortunately for you the solution may well be a new receiver.

I have the Genie, and my Marantz 8003 is able to handle what ever happened. There are enough reports now that this is only affecting certain receivers and TVs.

The only thing that surprises me is that your receiver is newer than my pre/pro, although it is a much higher end unit.

These codecs are all worked out years ago, but there is a big delay to implementation.

It might be as simple as the fact that your Denon can not decode HE-AAC. I understand there are units that can't. Everybody is switching to that as it is a much better quality audio codec and saves a lot of bandwidth. It has been around a long time, but only recently coming into very common use. I think it will pretty much replace all other codecs. You might want to ask Denon if your receiver can decode HE-AAC. If it can't, it is going to be pretty much useless.

After doing more digging around, I don't think this is an HE-AAC issue. As your receiver has HD radio it must be able to decode HE-AAC.

In any event I have found that broadcasters are not allowed to switch from AAC to HE-AAC because of the lack of backward compatibility.

I think you have a malfunction in either your Genie or more likely your Denon receiver. This might be solved by a firmware update.

The way to sort this out, is to see if your Denon firmware is up to date. If not. update with a cable Ethernet connection.

If that does not resolve the problem see if Direct TV will replace your Genie.

If that does not solve it then I think your Deonon needs replacement or service.

I run an x4000 with DTV and have no issues....never done a firmware upgrade either.

It is the genie system as mentioned.

Thanks for that post. That is really useful information.

I think that clinches it. He ether has a bad Genie DVR or his Denon is failing.

At least he now has ammunition to tell Direct TV that other Genie boxes work with that receiver.

Since the Genie is the new boy on the block that is what should be replaced first. However my instincts incline me to believe the problem is with the Denon receiver.

Interesting, thanks. I'll keep following as this is puzzling.

I sure hope so, I think.
Have not received any news yet, was supposed to be by this weekend that
DTV will send a more thorough system test via phone line I think (is plugged in now)
which is supposed to be more involved than typical tech support on the phone.

Since the Genie is the new boy on the block that is what should be replaced first. However my instincts incline me to believe the problem is with the Denon receiver.
Isn't it NAD that has the adaptive technology where you can do a system upgrade
of the hardware, by dropping in a new module? I forget what that's called, I was hoping
the Denon was that way, but must have been one of the other AVR's I was shopping for.
That's a very attractive feature/platform.

Since I'm integrating my mains through a second 28 yr old external amp via the AVR
since the mains require a bit more beef than the Denon supplies
I prefer to buy a cable to plug into the computer to update . All my cables and connections
on both the PC and the sound system are a nightmarish mess I'd rather not disturb really.
Even if the DVR gets replaced, I still want to do a firmware update, and hope that doesn't
mess up Audysseys settings or worse. I've never done a firmware update aside from the
likes of Windows, Mac, and a printer. So do wish me luck.

I saw the link you posted, and have located updates on the Denon site
but have not dug in yet to see if my vs is up to date or not.
Now that Winter and vacation's over, we're staying pretty busy.
Stoked to get this fixed. Could still be a number of things.

So…I think I've found the problem :oops:
or…could be a coincidence…

DTV could've sent a patch, or update while I was checking this but, read on…

If you go back to the OP post #1, the 1st thing I eluded to was
while I was out of the room, and the fact that my wife didn't remember
doing anything to the remote…well, it appears that my hopes that a setting
could be off, is precisely what it was, or a fix was just passed down.

Just wanted to complete this thread before it gets any further.

On the remote, I tried to change the presets i.e.. Movie, Stereo, Game and Pure.
The colored preset buttons. When I selected one, I had been going back through
the DTV settings toggling between Dolby Digital on and off.
Anyway when I select STEREO on the preset buttons, I get the issue repeating
which determines a fix was not sent down I believe.

Honest mistake and admit it, but do tell…
why on Earth would this cause specific channels to fail audio?
I'm sure I never had this before and have used all the preset modes.
Whatever the reason, at least this might be a new issue of compatibility
with DTV, and if others experience it, then a simple fix.
Sorry for all the man hours put in on this, remember it if anybody else
experiences it.

So any idea why Stereo mode would mute certain HD channels and not others?
I find it strange that 2 HD channels side by side on the tuner, would behave differently
or be interpreted differently with the AVR in stereo mode, all SD channels were unaffected that I tried, and turning off the Dolby Digital would cause all channels to un-mute, or to return the AVR to Movie
mode or select another setting in Stereo mode other than stereo.
Very odd and confusing to me how this happens.

By the way, DTV never followed up on the test they were to run.
