Kodi device not seen by Denon Receiver

I switched receivers from an Onkyo to a Denon 3313CI, and the Denon does not seem to see my little Kodi device. If the Kodi is connected to the receiver when the Kodi powers up, I can see the very start of the sequence, but then the display goes black. This happens for any HDMI input to the Denon.

Connecting the Kodi directly to the TV works fine.

The Denon has no trouble with any of my other HDMI devices. What could the problem be? Thanks.

I'm guessing, but any chance you're running 4K devices that require HDMI 2.0 and use HDCP? This video explains the potential problem with older HDMI standards:

Thanks for responding. The Denon isn't that old, it has 4K capability. I have to check with Denon because a Roku which had been seen by the Denon is now no longer visible. This is a story worth telling:

Like most receivers the Denon has a very elaborate remote and the unit is dead in the water without it. I like to have a backup remote but my faithful learning remote can't handle the Denon codes so I have been shopping for a universal remote which will operate the Denon. I tried two versions of the RCA units and the best they could do was turn the receiver on and off. Last night I tried a Sony RM-VZ320. The instructions that come with universal remotes don't give a key mapping so after finding that the power button can turn the unit on/off, you have to experiment with the buttons to find their functionality. So, I found that buttons 1-6 switched between different inputs of the receiver. So far so good. Button 7 seemed to switch to an aux input. Buttons 8,9 didn't seem to do anything until I found that if you pressed these buttons you lost the HDMI sound connection on whatever input you were watching when you pressed the buttons. After spending some time on the phone with Sony "technical support" it turns out that they have no idea of what the buttons do. Support means they look up the device code from the same data sheet that comes with the device. After spending over an hour trying to recover sound on the two inputs I lost because of the Sony I did a factory reset on the receiver and restored functionality on those inputs. However, the factory reset caused the Roku to disappear after it had been working with the Denon.

Good video, and setting up to watch this video revealed another shocking thing about the Denon: it seems that if no input is sending audio through the HDMI connection on any input to the Denon when the reveiver is turned on no HDMI input is recognized by the Denon. Some consequence of this may be my whole problem.

Thanks again Jeff.

There is no such thing as a "kodi device", kodi is software. Odds are it's one of those black boxes loaded with a custom interface sitting on top of an old version of kodi that can't be upgraded.

Have you tried to change the default settings?

home -> system -> settings -> system -> video output -> display

Try changing the resolution to something else, even like 1280x720 to see if the auto-default guessed wrong what it thinks it is connected to.

If you didn't build that "device" yourself, remember it could just be a Rasberry Pi under there which barely has enough horsepower to do 720p.

That means that all the HDMI inputs must be HDMI 1.3 or higher. 1.0 to 1.2 have audio, but only one bit, which might not work. If you're running a TV, it should be 1.4 or higher to get bi-directional audio.

It would seem that the HDMI port is "triggered" by the presence of a digital audio stream. Makes sense because it's cheaper to do at low audio frequencies than at video rates. If the Denon has an input "scanning" feature, where it automagically selects an HDMI source that is actively belching data, the lack of audio on the HDMI cable might explain why it's ignoring the Kodi device. There should be some way to disable this automatic input selection mis-feature in the settings.

What's inside the Kodi player? Raspberry Pi? Which version board? You should be able to lookup the HDMI version level for the board and see what it does with audio. My guess(tm) is that anything less than HDMI 1.4 is going to do strange things. Oh-oh: Looks like Raspberry Pi is HDMI 1.3.

The Denon is HDMI 1.4a. I got the Kodi to work, but I am still stymied by two of the inputs to the Denon. One problem I had, to use the Game input on the Denon, the receiver has to be set to the Multi-Media input setting.

There is something in the manual about triggering, I will play around with that. Thanks again.

Although I suspected that my device was a Rasberry Pi, I'm not sure. I thought it best to refer to as a Kodi device and let it go as that. I solved my immediate problem after finding out the receiver doesn't map the inputs at the back to the selections and display on the front.

For what it's worth:

If they didn't bastardize the kodi too much, you should be able to:

home -> system -> system info -> hardware

and see the type of processor in there along with the cpu speed.

Might give some clue to the guts.
