TV Hub Sound

Just received TV Hub.

I'm connecting it through an AVR. The AVR seems to detect the sound as Dolby Digital Plus and sets up to that, but when I watch TV there is no sound through the centre speaker.

It works properly when watching Amazon Prime.

If I reset the sound on the Hub to not be surround sound the AVR detects this and resets to Dolby Surround and the centre speaker works.

 

How can I get the centre sound in Dolby Digital Plus?

Just a thought, but can you change the AVR output to "straight" so you get the sound as broadcast?

Alternatively would changing the sound output to a theme (such as to sport or cinema) work?

Thanks so much for your help.

It may well be the TV, which I now know is pre 2010. No HDMI 2.0 or ARC back then!

Still odd that it all works fine when the broadcast is in surround (Prime or some BBC/ITV), but not when it's broadcast in stereo.

Only solution is to buy a new TV. I was looking for an excuse to do that!

Thanks again for all your help.

That might be the issue then. Similar to my old Yamaha AVR that did not support HDR but I could force the sound by switching from one AV then back to the correct one.

 

Unless you find someone with a similar setup that has 2.1, or you can borrow a recent smart TV and try the hub on, I'm not sure we can resolve this for you (I appreciate how unlikely this is)!

 

If I can think of anything else I'll come back.

Hub is connected to AVR.

 

AVR is connected to TV.

 

I'm pretty sure TV HDMI is not 2.1 as it is older than 2017. I looked at the TV manual and it did not say that the HDMI ports were ARC.

Another thought. Can you confirm if the box is attached to your TV or AVR please?

 

And do you know if your TV supports HDMI 1.4 or 2.1?

 

I'm wondering, having just read an article on HDMI Arc if your cable or TV only support HDMI 1.4 which may not have enough bandwidth to correctly decode the audio across all channels, unless you force it as you are currently doing.

 

This might be worth your investigating further.

There are HDMI out settings on the AVR, but if they can fix it I have not figured out how to set it correctly. 

 

Swapping the HDMI to another output made no difference.

Have you tried changing the HDMI out on the back to the other output from the one you are using? Any difference?

 

Are there any individual settings for the HDMI out that could need changing? My AVR has settings that can be changed. 

 

In case you dont have the full manual here's a link to the pdf

https://www.google.com/url?q=https://assets.denon.com/DocumentMaster/ENG/AVR-X2800HE2EA_X2800HDABE2_...

 

Re the optical cable, I dont think that is needed as the sound and vision are routed via the HDMI Cable?

 

Are you using the HDMI cable that came with the Hub, as it requires a 4k rated cable. Older cables may not distribute sound correctly.

I've got TT Hub.

Denon AVR 2800.

Old Panasonic TV, HDMI (not AVR), Optical out.

 

Something in the AVR set up may not be right because, although I set the TV Audio to optical out from the TV, when I pull out the Optical cable I still get sound coming through???

Maybe if you provide your TV make and model, and also your AVR someone here may have a similar setup and provide and answer.

 

A recent customer could get no HDR content to play via the iPlayer and it turned out his TV was not compliant, as required by the BBC, but other streams would play such content.

 

I'm not saying this is the case here, but maybe TalkTalk's tech team may have a view.

 

At least you seem to be able to force the sound with a workaround, not ideal but it may be an issue with the AVR. Did you look on other forums to see if there are similar issues reported?

I'm at a loss as to what else to try except a factory reset of the box, but I dont expect that to work unless there is a corrupted file somewhere that the reset will cure.

 

You can find the reset in the settings menu.

Amazon prime through the Hub works fine - Dolby Digital and centre sound.

Cabling looks OK.

 

Tried BluRay into same input, and it works perectly.

 

Issue seems to be sound signal coming out of TT Hub.

I tried removing the Optical but that made no difference.

 

But oddly removing the optical did not cut the sound, so I may have something wrong in the cable set up wrong.

 

I think I'll pull it all apart and recable and try again.

 

I'll let you know how that goes.

Also, do you have a straight setting so only the transmitted sound is passed through, rather than it trying to decide to surround sound, or are you already using such settings?

Have you tried just using HDMI Connection as the optical may be causing a conflict?

Still not solved.

My TV does not have eARC.

For TV channels broadcast in stereo I need to select "no surround sound" then the AVR switches to Dolby Surround, and the center speaker works.

For TV channels broadcast in surround I select surround sound on the Hub and the AVR switches to Dolby Digital and the center speaker works. 

Amazon Prime from the Hub seems to work no problem.

The sound from the TV goes to the AVR throughout an optical cable. 

 

Any ideas?

Morning,

 

Thank you both 🙂

 

@MrBevs1  How are you getting on?

 

Thanks

@Michelle-TalkTalk yes I do but don't have a surround sound setup on that TV.

 

The options are auto or none, don't use surround sound.

 

My understanding of the auto setting is that the box will select the type of output based on the programme information supplied by the vendor, so I think if it's Dolby it will parse Dolby.

 

As to the OPs issue it could be a number of issues like a non 4k HDMI cable, or a possible Ark issue between the TV and AVR.

 

I had and ark issue with my HD BluRay player that was connected to the TV. It couldn't decode the signal from the player to the TV and through the receiver quickly enough and that was using an 8k rated HDMI cable. I resolved this by plugging the Player directly into the AVR.

 

@MrBevs1 how is the Hub connected? Into the TV HDMI or direct to the AVR?

 

Have you tried switching to the other input, whichever you are currently using?

 

On my TV an LG I am able to change the sound and vision to HDR ( I use this for my BT pro box). Perhaps you have a setting value on the TV HDMI input that needs changing?

 

Have you also searched out a forum for your AVR? There may be similar issues there that may help and also a TV forum may help.one last thing about my own personal experience, my original Yamaha AVR served me well but then suddenly on Prime, when I got a 4k TV I could get no sound when a film was streamed using HDR. I found on the Yamaha forum that that model number was designed before HDR so it could not decode such sound. I ended up buying a new AVR in the end.

 

Hope my musings have given you some additional thoughts you may not have tried.
