The "Official" Denon AVR-4311CI/AVR-A100 thread [NO PRICE TALK] - Page 701

In cases where I can't level-match (and blind test), I've turned the supposedly superior source/component volume down, so that it is noticebly lower than what I'm comparing to.

Maybe an out of date question but can any one please advise what the latest firmware up date for the 4311 does or fixes or removes?

Thanks.

resolves Pandora related internet problems

Looks like the 4520 got an update this week? I guess we don't get one? (I know they are different AVRs).

At this point there shouldn't be any firmware updates to the 4311 (being an older, fully mature model) unless there is a specific bug fix (as with the Pandora update). The 4520, being much newer, still will get periodic updates to fix issues that come, generally with networking and HDMI handshake stuff.

Yea, I dont want any more updates on my 4311!

I've used a variation on that technique with level-matched tests, to compensate for measurement error. I turn up the inferior-sounding source by 0.5dB to see if the diff was due to insufficiently accurate "level-matching."

Thanks BP. Figured as much. As one that builds/maintains/crashes computers regularly, I update firmware on MBs, GPUs, SSDs, etc. constantly and sometimes they make a real improvement.

No, no level matching. Just my own subjective judgement. Dismiss it if you like.

Hi all,

I need some advice as something has gone terribly wrong and I am not sure how to fix this?

My 4311 has all of a sudden stopped playing HD audio, both FTS-HD and Dolby True-HD.

I try to send it to the amp via the usual methods but playback will not continue and no audio is recognised.

My avr works perfectly in every other respect which is strange, no errors, no issues etc.. It's working exactly as expected and when I tell my HTPC or blurry etc to send notmal dts, ac3, PCM etc they play perfectly fine?

I have made no changes what so ever to my player and/or my avr... It was working at 2pm as I played a movie, after watching i left the room, came back at 5pm and have been sat here since very confused?

The previous movie I watched today won't even work with HD audio and neither will new/different ones.

Is it possible to burn out or break only a HD audio decoders part of the avr and for the rest to still function as expected? Is this possible? Does it run/function in this manner? If so, I think I have broken my HD decoders chip but the rest are fine? Is this possible?

I'm so confused.

I hope someone can help me, also is this fixable... I think I may still have warrenty but shipping of this paving stone will cost me a fortune I expect

Also, does the 4311 decode AAC via hdmi, as I'm having issues with that too?

I hope someone can help,
I'm panicking that I have broke my avr

^Go into the menu and look at INFO->Audio Input signal. It will tell you what your player is sending. Highest suspicion is that this is a player settings issue, now decoding in the player and sending PCM rather than bitstreaming.

Thanks for the tip.. Im panicking here :-0

I've tried looking here but it's blank as when I try to send the hd audio the player says failed to initiate device, or not supported, or refuses to play etc.. Until I switch to PCM or normal dts ac3 etc...

On the front of the avr, nothing happens on the left hand side where the incoming speakers are located, it stays completely blank? when I switch to dts etc it lights up as expected?

Is it possible to break only the he audio controlled/decoder? Would it not e programmed to know its failed ad throw an error?

I've tried 3 players (blurry/hd HTPC/and ps3) and all refuse to send hd audio to my 4311 via hdmi, that thy have been doing perfectly for months...

I'm so stressed out, I'm literally devastated as this thing is my entire centre to my home media ... Anything else I can try?

Right. I didn't know if/how using HP you level-match.

Hmmmm....Ian, if you did NOTHING irt changing settings or connections just prior to this prolem, and noone has any other fix ideas on the thread, then I'd consider doing a reset the microprocessor procedure. First use Network Save and confirm the file on your HD is not all zeros. Then reset, then check if the problem is fixed, then Load the Saved file.

Thanks, Will do and will report back..

Does anyone know though, if its even possible for this to happen though... Can you "blow" the hd chip with out affecting the avr or it's other decoding methods? Is that even possible?

Do the Audyssey EQ check graphs show the amount of Audyssey correction, or do they show the speakers output previous to Audyssey correction?

 

I have a full 11.1 system.  Normal operating mode for me is DD+DSX fronts and wides.  This is for satellite television, movies, etc.  On some broadcasts, DSX does not sound good, so I turn it off, but it is usually on.

 

For music listening, I never use DSX or Neo:x, only PLII Music or Stereo 2.1.

 

The EQ graphs show correction with Audyssey, which is why they are called Audyssey EQ.  Of course, the EQ graphs are only a crude representation of the correction that Audyssey has applied, and are of limited value.

Hey,

Ok.. Micro processor reset has not resolved the issue? Does anyone know if I can play a sample file dts-hd or true-hd file via USB?

There are trailers in mt2s and mkv for dts-hd etc... If I put these on a USB will the (should the) avr play them?

Basically this would rule out the avr as being at fault and point to my source device/settings.

Is there any way to get a dts-hd file to play directly on the avr or is that just not going to happen....

Ive googled high ad low and can't find out if this thing should throw back an error if a decoder is faulty... If anyone knows if it's possible for an avr to break it's dts-hd, Dolby true-hd decoding chip but still function perfectly with no errors, or not, tht would help dramatically as I could rule it out as being at fault... Currently I have 4 variables ad can't narrow it down as they all connect to the avr and refuse to play hd audio... My weekend off and I've been sat here since 5pm (now 00:30) and tried everything and so stressed, not eaten my dinner, ignored the family and been swearing like a hooligan... Anyone

Hello Ian-do you have your 4311 manual? I know this may be a "reach", but on page 84, make sure your "audio input" is set to "auto", or "hdmi"(if you are using only hdmi inputs). Decode mode is next-make sure this is set to "auto" also. I know these are individual input "selectable", but at least it is something to check-and yes, they both should have gone to the default "auto", when you did the microprocessor reset.

It's extremely unlikely that the receiver could break in such a way that only the HD audio formats would stop working.
What player is the "blurry" player (brand/model)? Is the PS3 the slim version or the older version?

It would help if you tell us what Blu-ray player you are using. Also make sure that "secondary mix output" (a.k.a. "mix audio output") is turned OFF on your player. My Denon player also has a setting called "HD audio output" which has to be ON, perhaps one or two of these settings in your player are to blame for your problem.

Hey all,

I've checked the settings as mentioned and all settings are where they should be "auto" etc

My HTPC is HD compatible and uses MPC-HC etc and is all set to bit stream hd audio.
My Bluray player is a SLIM PS3 set to bit stream and i have a standalone Sony Bdp580 player too.

All of these items have worked perfectly until last night, The thing is, I can honestly, categorically state that nothing changed... I know that's hard to believe, but nothing was changed in any way shap or form.

If I could just test hd audio somehow, I could rule out the amp but currently all indications point to the amp having lost its hd udio decoding capabilities. This seems insane, but it's happening.

Is there any way to play hd audio directly on te unit via USB etc as currently it's impossible to fid the point of failure due to technical limitations imposed by the manufactures of each device.

I'm so frustrated

I will try this, as I have the same problem that you had, the receiver shuts itself off when playing 2ch music (for a few hours), although the receiver is quite cool to the touch. Incidentally I'm also a fairly new owner (the unit was manufactured last spring, as one of the last?).

This brings me to my question. Anyone know for sure what the 4 ohm setting does on the AVR-4311? You often hear in this forum that all it does is limiting the power and that you should leave it at 8 ohm. But what I find interesting is that when switching from 8 ohm to 4 ohm you can hear a relay clicking (this doesn't happen when you switch between 8 ohm and 6 ohm) and in 4 ohm mode the receiver "clicks differently" when you turn it off.

So what exactly happens inside the receiver when you switch to 4 ohm? (My speakers are rated at 4 ohms btw, but in reality moves between ~ 6 and 16.)

Refer to the bottom of post #1 for the firmware changelog information.

@ Ian Beale -

Try a few more resets .... at least 3-4 in succession. Also as a test, try setting the INPUT MODE = "HDMI" and DECODE MODE = "DTS" with a DTS HD audio track.

@ Ian Beale -

Have you tried using a different DVD player with a different HDMI cable to a different input? Even a cheap BluRay player would let you know right away if it was an issue with your current source and its connection to the Denon.

@wilbur and jd

Just doing this now, thanks for the advice and I'll let you know the results and how it all turns out. Totally devastated at the moment though

+1, except that I am opposite and usually leave DSX off. I found DSX to be distracting on "most" material, while adding an enhancement on "some" material.
