A few months back whilst watching a BluRay movie on the PS3 I'd intermittently loose the centre channel, and the surround sound bit remained. I fiddled with some user settings and everything seemed fine.

Occasionally I'd loose the centre but on Sky, but turning the TV on and off sorted things out.

Anyway I was just watching Captain Phillips on Apple TV and hey presto we have lost all voice etc from the centre bit. Any ideas?

Having to make do with Beverly Hills Cop on 4HD!!!!

Sorry just re-read your post - which answers my question! Did this happen on your old and new Bv11? I have never heard of this issue.

I've only ever had one 11! Has happened on the PS3 but when I changed user it seemed to work. Then I tried my user and again it worked.

But tonight using Apple TV it just dropped all the centre channel completely.

Now watching TV on Sky at volume 70, it's only an average level of volume. Isn't there normally a green light on the Beolab 14 sub? The satellites are working.

These days the LEDs on the speakers turn themselves off after a few seconds so you probably won't see an LED if the TV has been on for a while. I'll refer it to B&O and see if they have any knowledge of it. I have definitely not come across a BV11 doing anything with sound levels or center channel. Have you tried watching something on Apple TV that you know works?

Yes, and have just tried a BluRay, Love Film and a game on the PS3. Way too much bass when you don't expect it, far too much exaggerated surround sound.

Sky, Apple and PS3 all doing the same. Watched Beverly Hills cop on Sky at volume 70 and it sounded like volume 45! All speakers working, just not when and how they should.

Hi Chris,

don't know if that could help shedding a light to this mystery - but have you checked the 'sound mode' in the settings when 'your center is missing'?

WHAT!!!!

I've spent the last few months fannying around with my PS3' settings etc thinking it was them, and it's a known fault on the BV11 after all. Maybe this has something to do with my post last year about the sound quality on the BV11 and it;s associated distortion, which was dismissed in some quarters may i add.

If speakers can turn off by themselves, they can jolly well distort as well. The grief this caused me last year, almost lead my wife just to bin it in the local tip. These problems have been going on for over 6 months now, and i'm seriously unimpressed.

Hmmm Sturrock is correct - there is a registered problem that matches your symptoms exactly. It reads as follows:

Symptom:

Intermittently sound is lost from the centre channel.

This often appears to coincide with change of sound format to Dolby Digital 5.1 or possibly re-flagging of Dolby Digital 5.1 at a disc layer change.

DTS, PCM and Dolby Digital 2.0 seem to always work fine.

Deadline: 25/02/2014

Sorry i sent that post off before i finished it....

Workaround:

Was expected solved in SW version 1.0.5.33043. Unfortunately, it can still happen. Problem is re-opened and the team is working hard on a solution.

Pressing standby should resolve the issue.

Solution: official release expected end of February.

The above is copied directly from the internal technical knowledge base.

I can only apologise Chris - this information doesn't get sent out to customers and is only available if we go and look for it. As you are the first person to experience this issue and contact us about it, this is news to me too.

Means - if you set the playback device to decode all sound to PCM, the problem would no occur!?

Finished your glass(es) of red 🍸 ?

Idea was: if the BV11 (sometimes) has trouble with sound in DD5.1 being send from the playback device (PS3)  - and not with sound in PCM - all you would have to do is to let the PS3 do the sound decoding (to PCM).

Of cource you would have to change that in the settings of the PS3!

And you would have to do that anyway to have the benefits of the HD-sound formats.

My BV11 has the same issue/bug. And this without PS3. The BV11 itself has this problem.

I tried that a few months back when the problem arose, actually a lot of months back.

To be honest i'm so disappointed that this was a know fault all along(not by my dealer may i add), i'm in the process of selling the lot and being done with it all. I don't open the living room door and smile at what is a luxury item to be coveted. I did with my 7-40. I just want the bloody thing gone after the stress and bother it has caused.

I'll keep a few items, but has for B&O that we have owned for on and off for forty years, thats it.

@Hermann_

Of cource the BV11 has the problem - MartinW already described that and that there will be an update for it.

My suggestion was a 'workaround' if using the PS3 (or any nother Bluray Player) - and at the same time the advice to let that do the sound decoding (to PCM) in order to enjoy the HD-sound formats of a Bluray disc.

Please check out some of Dr. Mark Waldrep's posts on uncompressed sound.  Dr AIX . If you agree with him, you will either let your source do audio processing in the format of your choice, or output PCM to your BeoVision, on purpose.  The science on this stuff says you want it processed one time. Let the best processor/format have it.  

That will hopefully make the center-channel-failure an annoyance/quirk in your eyes and not a catastrophe.

Any idea when this fault is going to be fixed? Kids on half term this week watching Blurays...a lot. I'm sick of watching everything in the bedroom because the main tv decides to mess around with its channels etc.

I feel that the point at issue is that B & O's ability to respond to, and correct, an identified software issue is highly questionable.

 

As for the build, and aesthetic qualities of B & O TVs, they count for very little if the product is unable to fulfill  it's primary function.

I know this doesn't help, but volume 70 on a BV11?! I've never been above around 55, ever! Anything above 55 would be incredibly loud.

The kids are watching a movie at volume 56 now and your right, its quite loud. Occasionally when the TV decides to just do surround sound or some bizarre mix, even at 70 its muffled. Then the centre comes on, and it's deafening. This is an 11 issue Moxxey, not my 11. B&O know about this fault.

Remember all that grief i had about this last year, when even i began to doubt myself. Life's too short to be worrying about what AV solution your TV has install for you tonight. I got so fed up with it, last night i thought balls to it i'll take the kids to the cinema. We got there and sat down, to only get a phone call to say that our intruder alarm was going off, and most of Northumberland were unhappy about it.

It never rains..............

Sorry to hear about your problems,it's frustrating when you pay hard earned money on a luxury item and it lets you down.Granted had my 7-40 mark 6 a while,and has never missed a beat.

Get rid of it and get another bv7 40 or 55,it's a better all round solution in my eyes,with effortless sound and picture quality.

Your speaking to the converted trust me. When I has problems last year B&O and my dealer were very flexible and generous in trying to sort out the problem, hence the full Beolab 14 setup. But back to square one, and out of pocket due to a known fault!

If anyone wants to make me an offer, it's yours. I'm done.

I hardly expect this to assuage your annoyance and disappointment, but have you tried setting the Bluray player/PS3 to a fixed PCM output over HDMI?

Given that the issue appears to be the way the software in the BV11 is dealing with the DD metadata flag, I would expect this to fix the problem.

It's not really related, but in my V1-40, which, having the same digital chassis, and in part I would think very similar software, I team it with a Sony Bluray player.

In the setup menus of the player, I have the option of 'auto' (default) or PCM as regards whether I send either bitstream or PCM over the HDMI link.

The manual describes the 'auto' setting as: “Outputs audio signals according to the status of the connected HDMI device”

Since the last software update for the V1, I've noticed some odd behaviour when leaving the Bluray player set to the default 'auto' setting for audio over HDMI, and playing Blurays with DD True HD or DTS HD Master audio sound tracks.

If I played a DTS HD Master Audio 5.1, 6.1, or 7.1 disc, instead of automatically outputting multichannel PCM for which the processor in the V1 is capable of handling, it would output a downmixed DTS 2.0 channel mix - which the processor in the V1 is also capable of handling.

Similarly, if I played a DD True HD 5.1 mix, instead of outputting 5.1 PCM, it would output a downmixed standard DD 5.1 soundtrack, which simply showled up in the sound information display of the V1 as Dolby Digital 5.1 - again the V1 is capable of decoding standard DD 5.1, but not DD True HD - hence the player should be outputting the high res PCM soundtrack.

I updated the players software to the latest version, but this effectively made no difference.

I have no idea why this quirk suddenly developed as prior to this the player seemed to correctly determine which audio codec to send so as to correctly 'handshake' with the V1's processor.

However, setting the Sony Bluray players HDMI output to a fixed PCM, has cured the issue, as it now decodes all the various formats internally, and outputs the resultant PCM stream for the V1 - which correctly shows up in the sound info display as PCM 5.1, 6.1, 7.1 etc.

The internal DD 5.1 processor on the V1 is still used for TV broadcast, and when such a broadcast is in DD 5.1, again it is shown correctly on the V1 sound info display as Dolby Digital 5.1.

On the plus side, I'm probably imagining it, but the sound quality seems to have actually picked up by setting the Bluray player to a fixed PCM output - I'm wondering perhaps if it may have been outputting down-mixed audio signals for some time, depending upon the disc, and I simply hadn't noticed it, and it's now that I'm only getting the full benefit of the higher res soundtracks.

Well, that's a guess really, but the sound does seem better to my mind.

Unfortunately though, software is part and parcel of pieces of hardware these days in the AV world, and whatever one owns, there are likely to be upgrades, which may well bring some issues whilst solving others, and no brand is immune.

I have had two Sony ES AV amplifiers prior to buying B&O, and both of them had software upgrades during their lifespan - and nothing like as easy as doing it over the internet as we can do today; one had to download the files, decompress, burn them to disc and upgrade that way etc.

And I found that whilst there were some performance benefits, there were tradeoffs and some glitches too, so whilst not wishing to be an apologist for B&O given the difficulties you've been having, they are by no means alone when it comes to software glitches and the associated angst that goes with it.

Anyway, if you haven't already, may I suggest for your bluray movies, setting the player to a fixed PCM output if that is possible, as from the description of the problem, it should fix it,  and I'm sure that the software team at B&O will have a solution for the BV11 itself shortly.

All the best

 

John.. Cool

Thanks John, but it happens on all formats. PS3, Sky and Apple TV.

It hasn't happened since, so it's hard to replicate, but you just know it will. It's a small relief to know that there is a problem, and B&O acknowledge it. I spent tonight watching the trusty 8-32 in my bedroom because I just cannot be bothered with it.

@John

Sorry to say it - your suggestion was already made (by me) on the first page, and Chris also responded to it at that time.

Since he is having 'his problems' not just with sound from BRP discs - but also with sources where you have no direct influence on how/where the sound is being decoded (to PCM) - the 'problem' must lie somewhere else.

But where?

Hi Chris

The sound issue should be resolved at the end of February. I hadn't heard of this fault until it was flagged with me by a client some time ago. He owns a 46 with a sub and his current work around was to switch off the sub, our showroom model with lab 14 4.1 works perfectly, frustrating. The workaround is to put the set to St.BY, not practical when you're half way through a film!

The problem occurs when there is a change of sound format up to Dolby 5.1 or possibly re-flagging of Dolby Digital 5.1 at a disc layer change. B&O tell me DTS, PCM and Dolby 2.0 seem to always work fine?

Hopefully it will be sorted soon but not before the kids go back to school, so in the meantime down grade your TV to stereo?

All the best!

Hi w5bno123,

but there is no 'disc layer change' when you watch Sky or something from an ATV.

And I suppose that there is no 'change of sound format up to Dolby 5.1' 'half way through a film' on these sources.

And Chris has (if I understood him right) stated that his problem is still there, even if he has set the BRP to decode all sound to PCM.

Thus the problem must be somewhere else!

I am not 100% sure MM, this was the reply I received from DK internally.

It is probably something to do with the new True Image processing?

Just hope it's resolved soon, in the meantime we have a lovely 7-55MKII in need of a new home lol!

I predominantly get these problems when watching a movie louder than you normally would. Volume 66 say.

I've already spent half of last year sorting out the distortion problem, and don't intend wasting any more energy or life trying to get a £7,000 TV to produce some half decent sound. Thanks again

Seems to be an issue of the center/internal speakers shotting down at high volume, then!

And (maybe) redirecting the sound to the more capable speakers - just a thought.

66 is pretty loud.

Chris - have you ever tried to test the same movie (or music) at the same high volume level (for a longer period) with 'only internal speakers' of the BV11?
