Denon AVR-1910: Attached HDMI cable to HDP slot from a media

Customer Question

Denon AVR-1910: Attached HDMI cable to HDP slot from a media box I am borrowing from a friend that sends TV stations to me from around Europe over the internet. I attached directly to my TV and the picture worked but no sound so I connected to my Denon and now trying to configure it to output picture and sound. Help please.

Nathan :

Sorry to hear you’re having trouble. We’ll get started chatting here.
If you’d prefer support beyond the chat format, you may also reach me directly via phone or a remote support session. I’ll send an additional services offer for these options - feel free to ignore it for now, it will be available to you at any time during or after our conversation.

Nathan :

Well, you have a few options here,

Nathan :

One would be to leave it connected to the tv, and run a separate optical cable from the tv back to the denon for audio

Nathan :

the other is to adjust the input mode/assignment of the denon to match the port used.

Nathan :

For example, the input you're using may be defaulting to an optical/coax input

Nathan :

you'd need to go into the setup menu, into Digital Input Assign, and set your input port to hdmi (rather than opt/coax)

Customer:

Hi, the only option for me is to configure the denon - is this possible ?

Nathan :

You can also then set the input MODE to hdmi (rather than digital, or auto)

Customer:

I did that

Nathan :

Yes, these settings are adjusted quite easily from the setup menu

Nathan :

if it isn't working, then you can try a different connection, such as optical out of the media box to the denon (say on cable/sat mode)

Customer:

could I call u and u walk me through it?

Nathan :

if that still doesn't work, then the issue is an incompatibility between the denon and the box, meaning the denon isn't decoding the audio stream properly

Nathan :

You could, yes, but I'm in the US, and I do not have a toll free number.

Customer:

noi problem

Nathan :

by default though, that HDP port should be looking for hdmi audio.

Nathan :

can you initially try setting the denon on the HDP input

Nathan :

and then hit the small INPUT MODE button on the front, repeatedly, until it comes up to HDMI as the selection

Customer:

I think I already did this

Customer:

let me check and take a screenshot

Nathan :

ok

Customer:

Full Size Image

Nathan :

thanks

Nathan :

so that does look like it is properly defaulting to hdmi audio

Nathan :

and you say you did get audio when the box was plugged directly to the tv?

Nathan :

or you never had sound out of the box at all?

Customer:

no audio when plugged to TV

Nathan :

okay so that isn't going to be a denon issue then, it is something with the box

Customer:

but that's I guess because tv sound is off

Nathan :

does this box have an actual hdmi port on it?

Customer:

yes

Nathan :

Or is it a dvi port?

Customer:

hrmi to hdmi

Nathan :

Ok did you check that input mode button I mentioned earlier?

Nathan :

If still no luck there, then the next step would be to enable the tv speakers (temporarily) and test the box direct to the tv. If still no sound that way, it would at least isolate this as being an issue with the box and not the denon or tv

Customer:

I thought that's what I did

Nathan :

can you tell me the make/model of the media box?

Nathan :

the screen you sent is the input assignment

Nathan :

there is also input mode (an actual button on the front)

Nathan :

they work a bit differently though

Nathan :

because you can have multiple connections for some devices, and in some cases with a multizone setup you may have both analog and digital connections in place

Customer:

just says MAG250

Nathan :

so both the input assign which you already did, and the input mode need to be set

Customer:

small black box with HDMI and Ethernet cable port

Nathan :

Okay, well it looks like this box does have an optical port

Customer:

let me check input mode

Customer:

so the mag250 should work?

Nathan :

can you try using an optical cable to the denon (you'd need to use a different port, say tv, just to test initially). If that works, then we can adjust the input assign to associate the optical with HDP input

Customer:

what is an optical cable?

Nathan :

Fiber optic

Customer:

don't have one of those

Nathan :

see that little gray square port to the right of the hdmi

Nathan :

you don't have this?

Customer:

not the cablke

Nathan :

but you have the port

Nathan :

that is the important thing here

Nathan :

you'd have to get one of the cables,

Nathan :

but I don't really see any other option at this point

Customer:

so hdmi will niot work?

Nathan :

because it appears that for whatever reason the hdmi output is not working

Nathan :

it should, the box is built for it

Customer:

let me check the 2nd thing u asked

Nathan :

but it may be a firmware issue

Nathan :

ok

Customer:

Full Size Image

Customer:

Full Size Image

Customer:

Full Size Image

Customer:

nothing coming out when I git HDP

Customer:

hit

Customer:

no soiund or pic

Customer:

looks like we cannot solve this

Nathan :

all of your settings are correc

Customer:

damn

Nathan :

can you try the box directly to the tv via hdmi (with tv speakers enabled)?

Nathan :

at least then we'll know if it's just the box not outputting hdmi audio

Customer:

already seen that pic works

Nathan :

i mean hdmi audio

Customer:

audio not but tried to get sound on TV but failed

Customer:

ah

Customer:

could not find a way of getting to output sound

Customer:

tried a few obvious buttons

Nathan :

then it is an issue with the box not outputting hdmi audio

Nathan :

I don't know that you can "fix" that,

Nathan :

but there is the workaround method of using the optical connection instead

Nathan :

you just have to go buy an optical cable, which is only about $5

Customer:

so optical from denon to mag250

Customer:

can u show me what the end looks like

Nathan :

sure

Nathan :

you can order these online, or get at most any store that sells electronics, computers, etc

Nathan :

it will be called an optical, fiber optic, or toslink cable

Customer:

and the denon takes this

Customer:

so if I get this what do I need to configure

Nathan :

yes there are 2 on the denon, just to the lower right of the hdmi

Customer:

and how does the picture compare to hdmi?

Nathan :

exact same thing as you did before,

Nathan :

under HDP, but instead of HDMI under the input assign you choose digi

Nathan :

this is for audio only

Nathan :

you keep the existing hdmi cable in place for video

Customer:

so I have to connect the hdmi to tv directly?

Nathan :

you're using optical for audio only, it is a full bandwidth digital connection, it is equal to hdmi

Customer:

but I don't want to go directly from digibox to tv

Customer:

I want to go through denon

Customer:

for picture and sound

Nathan :

You wouldn't be connecting to the tv at all

Nathan :

You will use 2 cords from the box to the denon

Nathan :

hdmi for video, optical for audio

Customer:

but no picture is working so why would it work with an optical audio?

Customer:

if both come from denon

Nathan :

Because it is a different type of connection and processed differently.

Nathan :

You're getting video via the denon through hdmni

Nathan :

*hdmi

Customer:

no pictiure at all

Nathan :

optical is separating out the audio to a separate connection, since hdmi audio isn't working

Customer:

I think we miscommuncated

Nathan :

I thought this entire time that you were getting picture, but no sound

Customer:

nooooooooooo

Nathan :

ok that is something entirely different then

Customer:

that was direct from mag250 to tv via hdmi

Nathan :

if you aren't even getting video through the denon hdmi

Customer:

I am getting no pic or sound

Nathan :

then the hdcp functions of the box are not compatible with the denon

Nathan :

there is one thing you can try for that

Customer:

can I change the mag box

Nathan :

power everything off

Nathan :

then turn on tv first, denon 2nd, and box last (unplug power to box, then back in)

Customer:

ok will try now

Nathan :

I'm sure there are similar devices that will do the job, but most of them are probably not fully hdcp compliant either, due to the nature of the content

Nathan :

there is one other way around it, which is to buy a hdmi edid cloning device to put inline between the denon and the box

Nathan :

they are somewhat expensive, but it is about the only guaranteed way to make it work, other than using the split connections to the tv and the denon

Customer:

tried it but no change

Customer:

no pic or sound

Nathan :

okay, that is an hdcp incompatibility then,

Nathan :

basically, that means that the box cannot identify the tv as a secure display when passed through the denon

Nathan :

the only way around that is either the split connection (hdmi to tv, optical to denon), or passed through the device I just sent a link to

Customer:

ok thanks - not easy - will try the optical cable next and then get a telly with more than 1 HDMI input

Nathan :

Oh you only have 1 hdmi port?

Nathan :

There are also hdmi switch boxes you could use

Nathan :

they are pretty cheap, certainly less than a new tv

Nathan :

If wiring is an issue, such as with a wall mounted tv that has the hdmi cable buried in the wall, you could put the box at the output of the denon, so just a single hdmi cable to the tv, with denon feeding into the switch, and also with the box into the switch

Customer:

ok

Customer:

thanks - more challenges ahead then

Nathan :

You're welcome, and sorry there isn't a simpler option here.

Nathan :

If you have any other questions, just let me know. Otherwise, please do remember to rate my service prior to logging off, hopefully I have earned an “excellent”. I also invite you to contact me directly with any future support needs at http://www.justanswer.com/electronics/expert-p0llinate/

Thank you, ***** ***** a good day,
Nathan

Customer:

thx and u 2 - well my problem is not solved so cant give an excellent im afraid

Nathan :

Well I am confident the solutions I've offered will fix the problem, it just isn't as simple as changing a setting, which is due to the box really. That is outside either of our control.

Customer:

true - u get an excellent them
