Notebook > Receiver>>TV

So my receiver only accepts SPDIF as input and only decode DTS and Dolby Digital ( no HD formats)

When i play some DTS-hd file on players like VLC my receiver corrects "downgrade" to DTS, and it shows DTS on its display as normal.
With KODi on the other hand whenever i play a DTS-hd movie i got only stereo on my receiver.
The only way i can get 5.1 on my receiver in this situation is by enabling Dolby DIgital transcode on Kody settings. In this case i get dolby format on my receiver. 
Cant i get normal DTS on my receiver from DTS-HD format? Is there any detrimental effect on converting the dts core to dolby? 

Audio settings:
WASAPi output
2.0 number of channels
Enable passthrough
DTS capable receiver
Dolby capable receiver

I can post a debug log later if needed

Debug logs are always helpful, our psychic abilities do have their limits.

Sorry for the delay
This is the debug log with dolby ac3 transcoding enabled:
http://paste.kodi.tv/inogicocex - My receiver shows Dolby in the display

This is the debug lof with dolby ac3 transcoding disabled:
http://paste.kodi.tv/tajabebowo - i get only stereo sound

Either case i cant get DTS format on my receiver.

In your debug log I can't see where Kodi has enumerated an S/PDIF device (could be I just couldn't see it).

In my setup (Win8) I have Intel HD Graphics and a Realtek S/PDIF output, so my default audio is HDMI and my passthrough device is WASAPI S/PDIF - which goes to my receiver.

My Kodi audio settings are:

Audio Decoder

Audio output device: DIRECTSOUND: HDMI - Panasonic -TV (Intel® Display Audio)
Number of channels: 2.0
Output configuration: Optimized
Volume control steps: 90
Maintain original volume on downmix: [Yes]
Stereo upmix: [No]
Resample quality: Medium
Threshold for pitch correction: 2
Keep audio device alive: 1 Minute
Send low volume noise: [Yes]

...

Audio Passthrough

Allow passthrough: [Yes]
Passthrough output device: WASAPI: SPDIF - Realtek Digital Output (Realtek High Definition Audio)
Dolby Digital (AC3) capable receiver: [Yes]
- Enable Dolby Digital (AC3) transcoding: [Yes]
DTS capable receiver: [Yes]

So I'd suggest checking that you can output normal Windows sounds to your receiver via S/PDIF, and then double-check your Kodi settings.

With DTS-HD audio media, I get DTS out to my receiver (it has a DTS light on it so I know it's not getting DTS transcoded to Dolby Digital). It gets the DTS core also when Dolby Digital transcoding is set to Off, as expected. (The reason I have DD transcoding set to on is for multichannel FLAC music).

Hope that helps.

 So the reason you didnt se a S/PDIF device enumerated connection is because my windows output through HDMI connection. Then i have a audio extractor that receive HDMI as imput and output the audio as S/PDIF to my receiver. WIth this exact setup i can get DTS on my receiver when playing DTS-HD files with VLC and mpc-hc players. I tried your settings on kodi with no sucess.
