Hi,

I'm also one of the happy owners of a beebox-s kaby lake. I'm reading that some people have some HDR issues but I'm stuck at some audio issues regarding DTS-HD , DTS-X and TrueHD

It seems like my receiver (Onkyo TX-NR646) continously freaks out when I use Audio Passthrough in combination with one of the audio streams above. This happens only when I activate the feature Videos -> playback -> Adjust display refresh rate "always" or "on start /stop".

When I disable this feature The newest HD codecs are working just fine. So I'm sure it has something to do with this Kodi option. Since Kodi is performing some corrections for smoother playback it seems logical that my receiver could freak out about this I guess.

But Tthis raises some questions for me:

- DTS audio passthrough is working fine with the refresh rate setting enabled. I find it odd that only the HD lossless streams are not working.
- Why does other people don't need to use the refresh rate adjustment? Is this because of my television? Should a new television be an option? The one I use now supports Full HD at 60hz. Or do they just don't care that the video stutters sometimes.

Other options are
- Don't use audio passthrough, I will probably don't hear the difference so much with my 5.1 setup? I need to verify this myself
- Use Audio passthrough and disable the DTS-HD and TrueHD .
- Since DTS is working just fine maybe I can ask Kodi to look into this issue?

Best regards,
Stijn

nothing to do with Kodi, it's a Linux kernel/driver issue with any device with the same Megachips DP->HDMI converter chip. HD audio streams aren't passing thru properly, so we just have to wait until there's an upstream fix/patch. It's being worked on / tested daily, I can tell you that

I think some people will find this interesting:

this here is from an intel nuc blog:http://nucblog.net/2017/02/nuc7i3bnh-rev...nclusions/

.....If you are running HDMI firmware earlier than 1.66 you will have problems with the audio passthrough to an AV receiver that is HDMI 2.0 capable. After the update, which can be downloaded on the Intel Download Center, all audio formats should work fine......

The official firmware update on the beebox support site is still v1.61. I'll try the new version out tonight and will give some feedback on the audio passthrough for trueHD and DTS HD
