    NUC6CAYH - 5.1 Audio not working via HDMI

    StanciFUC

      Hello,

       

      I am recently bought NUC6CAYH to work with my ONKYO HT-R393 Home teather witch supports HDMI2.0, but it seems that I am not able to get 5.1 sound via  HDMI connection.

       

      I am using UBUNTU 16.10 and already tried 16.04.02 with the same result. I am able to only use STEREO even there is an option in Sound control to set HDMI 5.1 and 7.1.

       

      After switching to 5.1 there is still working only 2 speakers. Situation si even worse when trying to play movie (x.264). I only hear background music of the movie but not the voices of actors.

       

      Do you know where should be a problem ?

       

      I aqm really frustrated as I bought NUC to be HTPC and for playing the movies in x264 and x.265

            Thank you for your reaction  to my topic.

             

            I am not experiencing any issues while running Windows 10.

             

            Unfortunatelly I can not send you data throught Intel System Support Utility from affected system  as I have problem with Ubuntu as mentioned before.

             

            I am attaching files colected on Win

             

            My A/V receiver is Onkyo HT-R393 running on latest firmware.

             

            I am using PremiumCord HDMI 2.0 High Speed + Ethernet  cable  with product number 8592220014247 , but I also tried couple of HDMI 1.4 cables with same result.

                Hi StanciFUC,


                I would think that if you don’t see this issue when running Windows 10 then it has to be drives related, Intel doesn’t provide drivers for Linux and Linux operating system validation is limited.

                I would recommend that you try drivers and patches available at: https://01.org/linuxgraphics/downloads/2016q4-intel-graphics-stack-recipe this is the only recommendation I have at the moment.

                I hope this helps.

                 

                Regards,

                Ronny G

                    Hi,

                     

                    I just purchased a NUC6CAYH and installed ubuntu 16.04.2

                     

                    Multi-channel (5.1 or 7.1) audio dolby digital and dts do NOT make it to my Yamaha receiver from Kodi.

                     

                    I think the "assumed answered" status on the original question is incorrect.  It certainly misled me into thinking nuc multi-channel sound worked under ubuntu.  I'm certainly feeling buyer remorse!

                     

                    I've tried disabling pulseaudio and using alsa instead per this:

                    http://kodi.wiki/view/PulseAudio/HOW-TO:_Disable_PulseAudio_and_use_ALSA_(without_removing_PulseAudio)_for_Ubuntu

                     

                    I certainly got different options in Kodi's system/settings/system/audio output, but Kodi starts up with a red 'no sound' icon in the upper right corner and no changes I can make will turn that off.  And no sound at all.

                     

                    Edit: May 29 - 

                     

                    With the stock config of pulseaudio, I never got anything higher than stereo via HDMI.

                     

                    somehow, struggling with different settings, the volume in Kodi got turned off.  That's what the red 'no sound' icon means.  After turning the volume to max, I DID get 5.1 (dts and ac3) working via hdmi in Kodi.  I NEVER got optical Toslink working at all.

                     

                    I disabled pulseaudio per above link, and chose the following in Kodi's system/settings/system/audio output/

                     

                    Audio output device: "HDA Intel PCH, GSM LG TV on HDMI #0"

                    Number of channels: 5.1

                    Output configuration: optimized

                    Stereo upmix: not selected

                    Maintain original volume on downmix: selected

                    Resample quality: medium

                    keep audio device alive: 1 minute

                    play gui sounds: never

                    Enable passthrough: selected

                    Passthrough output device: "HDA Intel PCH, GSM LT TV on HDMI #0"

                    Dolby digital (ac3) capable receiver: selected

                    and everything else capable receiver: selected...

                     

                    I suspect, unless you also own and LG TV, you might see your own device on HDMI #0.

                     

                    While playing a video, press keyboard "Enter", select speaker icon to get "Audio and subtitle settings" dialog.  I chose the following:

                     

                    Volume at: 0.0 dB

                    "Enable passthrough"  selected

                      Some thoughts...

                       

                      Have you checked for updated graphics/audio driver package(s)?

                      Have you tried installing the Ubuntu 17.04 release instead?

                        No to updated graphics/audio driver packages - mostly because I haven't found anything nicely packaged that can be installed and removed via apt-get.  I'm not into fiddling around with low-level drivers manually.

                         

                        No for Ubuntu 17.
