Intel NUC and separate audio & video outputs

[Rijard]

Good morning,

I have NUC D34010WYB. It has miniDisplay port and miniHDMI port.
I would like to send video through miniHDMI directly to TV and audio through miniDisplayPort to AV receiver.

Now, in KODI/audio settings I can see an option where to send passthrough stream.

First, "HDA Intel, HKK SII SRPT RPT on HDMI" may be the HDMI port connected to AV receiver (Harman Kardon BDS)
Second, "HDA Intel" with no details may be the display port, with nothing connected at the moment.

(There is another ALC283 analogue port listed - that is jack for headphones)
If I choose for audio stream a different port where I send video output, unfortunately I cannot hear any sound.
If I use one output at time for both audio and videostream, it works fine on both ports.

So my question is - does KODI on Open ELEC support simultanously two output ports? One for video, other for audio?
Any ideas, what I am doing wrong?

Yes of course you can send audio to a different device than video. Have you tried both HDMI ports shown (I think DP shows up as HDMI).

Of course I did! And this didn't work - that is exactly my problem.
After posting my topic, I start intensively testing overnight
It was working fine with video via DP to TV, but audio via HDMI gave no sound.
On the list of sound outputs there was "HDA Intel, HDMI" (there should go audio) and "HDA Intel, MEI Panasonic TV on HDMI" (here goes the video). It looks, like Kodi doesn't recognize the target on the other end of cable...
So I play with cables, reconnecting different ports, updated BIOS in NUC, bypass HK completely, put it back...shortly after 4 hours of experiments it started to work as required. :woohoo: Unfortunately don't know the particular step which caused it working. Anyway...
Now video goes to "HDMI1" (mini HDMI port) and audio goes to "HDA Intel HKK HDMI TV on HDMI" (display port). Same with passthrough option.

Everything works as I need.

Only two questions remain...

1. Why I cannot see two video outputs on chosing where to send video? I see only "HDMI" and "Default". No "HDMI2" (for DP). It appears only and only when the only DP port is connnected. Once both ports are utilized, seems, that NUC choose one of them as default and send KODI only one video option... (?)
   
2. What does mean and where they come from all the abbreviations in description of audio outputs? HDA, HKK, MEA Panasonic, HDMI TV on HDMI, etc.

I am not sure why your results are as they are.

Do make sure that when you turn the NUC on, that all pugs are in place and both the amp and the TV are on. EDID info on the video and audio capabilities of the TV and Amp are obtained during starting X.

The abbreviations are probably supplied by the EDID info from th TV or Amp.

Video and audio devices are distinct. Both may be called HDMI, but they are distinct and separate.
