Dolby Digital Plus and Netflix on Various AVRs - Page 2

post #31 of 291

I'm experiencing this exact issue ever since having replaced my phat PS3 with a new PS3 slim. I have a Denon 3311CI. When I disable DD+ in the PS3's settings, the problem goes away. However, I just read (here: http://digitalhome.ca/forum/showthread.php?t=156135) that this downgrades everything to Pro Logic. I'll have to check it out tonight.

Gear mentioned in this thread:

Just a followup from the other day, Tested REDEMPTION on the X-4000 thru the OPPO and no issues at all. Could test on the 2113, the AppleTV will not stream DD+ and neither will the Sony BDP-460

I've been trying to figure out if it's just a bad audio encoding or if it was the Chromecast doing it when I stumbled on these messages. I think I noticed it through a WD TV Live as well, but that may have been wishful thinking to convince myself it's not the Chromecast's fault.

Does this sound like what you all are seeing? I have an Onkyo 414 in my basement I may hook the Chromecast to and test it with that now, but I really don't want to replace the Denon as my main AV receiver since it has dynamic volume and the Onkyo doesn't.

Thanks!

I'm so happy I found this post! I've been noticing the EXACT same problem when I play 5.1 Netflix through my Denon AVR-1613, S's and F's sound like low bit-rate artifacting or echoey. It's unbearable! I first noticed it a month or 2 ago on my Chromecast and couldn't find anyone with a similar problem, I thought it might be just my Chromecast, but it happens with the PS3 as well. I notice it in Supernatural episodes and other movies/shows that have 5.1 surround, problem goes away when I switch to stereo on Netflix. How can we fix this!?

Call Denon. The only way we'll get this 'fixed' is if Denon gets enough reports/confirms the issue is on their end, and releases an update.

Im still not 100% convinced this is a denon issue as opposed to a netflix issue. Poor audio streams can result in poor sound in the end.

I'm curious as to what denon says.
post #36 of 291
I've have the exact same issue with my 2113ci. I just assumed it was bad encoding until I switched Netflix's output to stereo and it sounded great.

I first noticed on Breaking Bad episodes. I am streaming with a phat PS3.

I've spoken with Denon and linked them to this thread. They are looking into it. Great customer service so far! One of the techs emailed me after I mentioned the thread existed asking for a link. Doesn't get better than that. Hopefully they can figure out where the problem is and sort it out for all of us experiencing the issue.

Keep us updated if/when you find anything out.

An AVR-2113 owner here checking in with the same issue.  I've just set up Windows 8.1's netflix app with superhd and dd plus, and have a fast central London connection - no dropped frames or noticeable visual degredation, but as above, the "s" and "f" centre speech sounds are quite lossy, sounds like it's coming through at 16kbps.  However, sometimes it seems to come right, I've not worked out if it's an intermittent issue yet.    Thanks for looking into this, Denon!

post #40 of 291
Created a new account just to post this. I'm having the exact same problem. AVR-2112CI, DD+, Netflix via Chromecast. I'll call Denon. Please keep me posted!
post #41 of 291
Just wanted to update everyone. Got a call back from Denon's testing lab a few days ago - they reproduced the problem and basically acknowledged that they were hearing the same crappy sound. They told me they had to forward it to their hardware development lab people to get a sense of what was causing the problems and how they might go about a fix. Haven't heard back from them in a while but do have a case number so maybe I'll follow up later today. I did post something on Reddit and had someone posting saying that they were having the same issue on a Sony receiver... which is strange. Either it's a buggy implementation of DD+ that multiple vendors are using, or Netflix has a problem with their audio streams... The problem is if you call Netflix I'm sure they'll tell you to call Denon.
post #42 of 291
I thought I would report that I'm having the same problem too. I have an Denon AVR-4311CI, Chromecast, and Netflix. S's and F's are very noticeably "underwater" or something like that. Like an earlier poster said, it is like listening to a 16kb/s stream of talk radio. I was noticing it on "How I Met Your Mother." On that show there is a *swoosh* sound effect that they do when cutting to flash-backs, and it's audible on that too. It's not a smooth *swoosh* but a rattly sound, like someone rolling their tongue on an "R" sound.

I also should note that it seems somewhat intermittent, and very well could be a Netflix issue.

Anyway, I hope this can get fixed.

I think its a Netflix issue myself but I'm not having the problem with 3 Denon receivers and 2 Panasonic BD players streaming Netflix.

If its happening on somebody's Sony receiver also then I'd say Netflix is the problem.

thanks for the update. its nice to know denon is interested in hopefully getting to the bottom of this. I still think it is entirely possible this is a netflix issue though.

i stream netfilix from a denon 1611 blu-ray player, a sony 70 inch tv, my pc, and 2 different play station 3's to a onkyo 809 avr and a denon 1611 avr and thus far have not been able to replicate the issues reported here on my gear. the closest i have been able to get is SD 2 channel stuff sometimes has harsh highs - i chalk this up to poor quality source material. No audible artifacts in DD streams thus far though.

A reasonable amount of Denon owners are having this issue (to put that into context, all 3 local Denon owners I know have experienced it) - that doesn't mean it's a Denon issue. It does mean whatever the issue is appears to affect many Denon owners. Now that Denon has replicated the issue and can get to the bottom of things (be it an issue with their HW/SW or Netflix), they can either provide fixes for their HW/SW or talk with Netflix on a level that most on this forum can't (which may result in actual fixes). It's win-win for everyone, as I'm sure others, and myself, are not happy watching Netflix in stereo on our expensive setups. Netflix may not listen to individual users with an issue, but if a manufacturer contacts them with details of a problem (if it is a Netflix issue) I suspect they'll be much more receptive. Too many people play the blame-game or the not-to-blame game, there's no point in getting stuck in that line of thought. I, as a consumer of streaming video/audio, just want it to work. It really doesn't matter to me who is responsible for the artifacts/sound issues we're encountering, I'd just like it fixed. Denon recognizing/replicating the issue and acknowledging it is a huge step in this process, and kudos to them for listening to their customers. I can't say the same for Netflix.

I joined based on a quick internet search that yielded this thread. I do NOT have a Denon receiver, but am experiencing the same issue. I have the following:

Sony STR-DN840 receiver
Sony BDP-S5100 Blu Ray player

I use the blu ray player to stream netflix and have the same issues. It is apparent in ANY RECEIVER mode including 2 ch stereo. When I change netflix to stereo mode the problem goes away. Just thought I would let the Denon folk know they are not alone. Frustrating

Just heard back from Denon:

"We did escalate your issue with the Dolby Digital Plus to management that you had raised and found it was verified/escalated to Japan for a future firmware fix a couple weeks ago, so check for available firmware updates in the near future (check every couple weeks or so on the Denon) as they should try to work this in."

Awesome CS! Sounds like we have a fix coming our way. I was in contact with them re: a 4520, so I don't know what other receivers will be getting this treatment. I do suggest talking to support if you're having this issue.

This is great, a big thanks to everyone who has dealt with Denon on this issue. If we do indeed see a firmware update as a result of this I will be a happy camper!

Just saw a firmware update on my E300! Didn't get a chance to download it and can't find anything about it online... Wish I could find some patch notes!
post #50 of 291
Confirmed issue on Denon AVR-X4000. When watching Nightmare Before Christmas with Dolby Digital +, at the 15-16 second mark the audio in the center channel cuts in and out. Also, noticed throughout the intro song that the sound was overly bright, probably the cause of the sibilance described above. Switching to stereo resolved both issues.

Watching (listening) from PS3 slim in bitstream mode. I might try switching to PCM to see if the problem is resolved, as then the PS3 would be handling the decoding.

Another thing I thought of, I have a Pioneer VSX-1021 that works with DD+ from Netflix. It wouldn't be too much trouble for me to hook it back up and determine if the problem follows the receiver or Netflix.

So I finally got my receiver back from Denon, they could not reproduce the issue.  This is despite me explaining exactly what the issue was to their repair people.  Very disappointed with Denon at the moment!

Firmware change log notes are posted in post #6 of the Denon AVR E/X Owner's thread ....

post #54 of 291
I am also experiencing this exact issue (distorted audio) on the Denon AVR-X2000. This occurs when the receiver is showing Dolby Digital Plus while I am watching Netflix from a PS3 slim (bitstream). This was driving me nuts, and took tons of trail and error before I was able to eliminate the problem by unchecking DD+ as a supported Audio format on my PS3. I only found this thread afterwards. frown.gif

I don't think it's a Denon issue.  I just recently (last 2 weeks?) started to have the same problem streaming DD+ tracks in Netflix via Roku 3, into my Pioneer AVR.  (It's not an internet speed issue.  I'm getting 18 mb/sec, hardwired.)  Like the previous users reported, "f" and "s" sounds come through very digitized; very sharp/static like.  There is a scene in Johnny To's "Vengeance" where a woman is cooking in a hut on a beach.  The waves on the beach come through somewhat sizzly and the sound of the steam from the woman's pan is unbearably harsh.

 

I posted the same issue on the Roku forums.  Someone else there said that Netflix recently changed their bit rate on DD+ and because of that my AVR has trouble processing the signal.  If this is in fact true, and also the reason for the distortion on DD+ tracks, generally speaking can AVRs be configured to deal with this kind of issue?    Can I tell my Pioneer to decode using regular ol' DD when it's getting a DD+ signal?

I am having the exact same problem on a Marantz SR 6008 with a ps3 slim.  Same result, turned off dolby digital plus and it went away.

post #57 of 291
This is not a Netflix issue. I have an Onkyo TX-SR805 and a Yamaha RX-V573 and they both play Netflix Dolby Digital + streams perfectly. I recently picked up the Yamaha receiver for my bedroom system (to replace an older failing Marantz SR-5200) and chose it over comparable Denon and Marantz receivers precisely because of this issue. I'm sure Denon/Marantz will have a firmware fix for this but I didn't want to wait and got a receiver known to handle DD+ streams properly right out of the box.
post #58 of 291
Just went back to the beginning of this thread and read the stuff batpig and jdsmoothie posted, you guys are great. Problem that often happens in this forum is information overload.

Happy with my X2000 so far. Resigned to having to manually switch between Dolby and and multi-channel stereo. It's really only used as the sound source for the home theater. RARELY use it for anything else. Basically have no interest in streaming music. Might want to do streaming movies at some point. Currently I just have all the movie channels from FiOS (used to have DirecTV). Might want to do NetFlix.

I really don't want to run ethernet cable to the AVR or TV (not good options). Thinking about a WiFi bridge. Interested in opinions.

Would the NetFlix come through the TV or AVR? IF it came through the TV, would it require the the ARC or a separate audio signal?

Sorry for being such a dweeb. Looking for networking answers.

Still having this issue on my end. I'll end up just completely ignoring DD+ as DD 5.1 comes in fine, even if there is a firmware fix I'd have to send my whole unit back to Denon and the cost of shipping would make that unreasonable for me. I'm glad I brought it to the attention of people though and I do hope we get a fix from someone!

As far as I know, Denon has not yet released a firmware update addressing this. My projector is being serviced right now, so I haven't been able to check for updates, but I haven't seen any note of a firmware release yet. Thank you for making your post, it's what motivated me to chase Denon on this one until I got confirmation from them it was an issue and would be addressed in a forthcoming update. I just hope it's sooner rather than later!
