X4400+FireTV+Atmos=Staticky Audio

[Drunkpenguin]

Finally got my 4400 and hooked everything up. I'm doing a full 7.2.4 system and everything sounds great, but one small issue. When streaming content from the FireTV and choosing Dolby Atmos to upmix I get this awful staticky sound. I can still hear the audio and the dialog, but it sounds how a speaker sounds when a wire is shorting out on something. If I switch to DTS Neural X the problem goes away. Atmos also sounds just fine through my Bluray player. I tried setting the firetv to both auto sound and dolby digital plus.

Any ideas?

What is the Fire TV outputting? Is it Atmos or just Dolby/Dts?

If you do not use DSU and just play it as is does it still crackle?

Well, today I cant get it to do it. Seems to have fixed itself while I slept.

Sleep can fix a lot of things.. If you were upmixing from 2 ch stereo, you might can that kind of noise with certain codec.

Love it when that happens! Wouldn't surprise me if Amazon snuck in a quick little update while you were sleeping. Not kidding.

That's good to hear. Hopefully the problem stays away

Just out of curiosity was the stick plugged directly into the Denon or off on an extension?

 

[Drunkpenguin]

Its not a stick, one of the original boxes with an hdmi cable.

Ok, was just a thought

Other than that, how is the Atmos working out, are you noticing a difference?

I havent even gotton a chance to watch a movie. 3 day weekend has turned into a working weekend. I have run some demos like the atmos trailers tho and its pretty impressive tho!

Drunkpenquin, I've noticed the same on my 5.1. I have a fire TV 2nd gen box. The audio it lets me choose is
: DD+ auto
: DD+ off
: DD+ over HDMI ✓
: DD over HDMI
I have the one checkmarked selected and I get that same intermittent cricket noise. I don't hear it when on Netflix or yt or any app only on the main screen. My only fix to kill the noise was DD+ off selected....but that defeats the purpose

 

[Drunkpenguin]

I'll have to double check where I left my set to. I haven't had the issue recently.

I have my fire Stick setup to DD+ over HDMI and no static problems. I don't have Atmos though. Maybe try another Hdmi cord.

Is it like the static on the TV like in the Ring? Or like in poltergeist?

 

[Drunkpenguin]

Have you ever heard a speaker that had a bad wire connection? Like if you slightly shorted out the positive and negative? It sounded like that, but from all speakers.

That’s strange it would make that noise.

Doing a quick Google search, it would appear that you're not the only one having the issue. One guy said Amazon responded to him saying they were aware of the problem and are working on a solution. My guess is it's something software based on the Fire TV side. Also saw one guy saying he isolated the problem to some app running in the background. A podcast app. He removed that and the problem went away. Have you given Amazon customer service a call? Not that they'll do much, but hopefully if enough people complain about the issue, they'll actually work on an update that fixes that specific issue.
