        Hi Wanner G.

         

        Your welcome, I really appreciate the time you take figuring out whats wrong.

         

        These devices are connected and all work correct:

        - XboX One X: directly to TV on HDMI port 2

        - Horizon Set top box (Ziggo digital TV): directly to TV on HDMI port 3

        - Soundbar: directly to TV on HDMI port 4

        - Nintendo Switch: through soundbar on HDMI (only one input HDMI)

         

        I have also tried different setups in which the other devices all worked properly. No other devices show up in Sound settings or under playback devices except for what I've posted before in the screenshots.

         

        - The NUC is connected directly to the TV on HDMI port 1

        - The soundbar is connected to the TV on HDMI port 4

         

        Audio drivers on NUC are the following:

        C:\WINDOWS\system32\DRIVERS\dmk.sys

        C:\WINDOWS\system32\DRIVERS\IntcDAud.sys

        C:\WINDOWS\system32\drivers\ksthunk.sys

        C:\WINDOWS\system32\DRIVERS\portcls.sys

        C:\WINDOWS\system32\SysFxUI.dll

        C:\WINDOWS\system32\WMALFXGFXDSP.dll

         

        I hope this helps!

          Hello Michel020,

          Based on the screenshots provided, the TV should not be handling the audio output of your HTPC. There should be a setting on the TV to bypass that behavior and allow the setup to recognize the Intel® NUC and deliver 5.1 Surround sound. Using an AV Receiver may also be a solution to this issue.

          Now, because your Intel® NUC 515RYK used to work with the same configuration, I will do further research to get as much information as possible and provide a detailed answer about whether your unit may be experiencing compatibility or driver issues.

            Hi Wanner G.

             

            The TV is not handling any output from the NUC.

            It's been connected the same way as my former NUC. The only options the TV provide is to disable the internal speakers for the use of an extrenal device, in this case the soundbar. I can enable them, disable them or set it to automatic (EasyLink).

             

            It's the drivers for Windows that only allows 2.0 audio. If I recall correctly my former NUC also showed the possibility of 7.1 audio for example. Something I've never used because the soundbar has five speakers and a subwoover. But when I did a test, I heard six beeps (5.1 audio). When I do a test now, where only 2.0 Stereo is available and any other sound configuration is greyed out, I hear sometimes a tiny beep and sometimes nothing at all. I can't even test the speaker settings properly because I don't hear a thing. But I do when I use MPC, VLC player or KODI for example.

             

            To me it looks like it has something to do with the drivers since every other device work perfeclty fine on any port and with any cable. But then, my knowledge is limited.

             

            Thanks again for all the time and effort you put in to this and I hope this can be figured out!

              Hello Michel020,

              Thank you for the information provided. 

              In order to find a solution or a workaround to this issue, I will provide this information to the proper department. I will post an answer as soon as possible.

              I will get back to you soon. 

              Regards, 

              Wanner G.

                Hi Wanner G.,

                 

                Thanks again! I found something perhaps worth mentioning since it didn’t occur on the NUC 5i5RYK.

                 

                When the former system was on, but didn’t play any sounds, it just stayed connected. As if there was a constant signal from NUC to TV. With the 7i5BNK it looks like when I don’t play any sound, the ARC function works differently. ARC on the soundbar starts blinking and the sound icon in the Windows taskbar sometimes shows a red dot with a cross. As if no speakers are connected.

                If I go to the properties of the sound, the Philips FTV can’t be found anymore until I reboot. Also, there is no energy save option on the soundbar, but as I wrote before, this didn’t occur on the 5i5RYK.

                 

                I hope this information helps!

                  Hello Michel020,

                  Regarding the ARC behavior on the soundbard and devices in sound properties, do you have to reboot your Intel® NUC in order to hear any sound when playing music or videos? Try playing music and check this behavior again.

                  Now, follow the steps below and share your findings to continue troubleshooting your Intel® NUC:

                  -Connect only your Intel®NUC to the TV via HDMI and attempt to get 5.1 sorround sound.

                    Hi Wanner G.

                     

                    Yes, I do have to reboot the NUC in order to hear sound after this occurs.

                     

                    In the settings, still only 2.0 remain available.

                        Dear Wanner G.,

                         

                        Has there been any news on an update lately?

                         

                        I've some extra information that may be usefull:

                         

                        When I'm using Windows on the NUC and switch to my Xbox (with the NUC still powered on), the audio in Windows is gone as soon as I switch back to the NUC.
                        I have to reboot the NUC to regain audio in Windows.

                        So essentially the only thing I do is switch from HDMI port 1, to HDMI port 2 on my TV and the signal is gone.

                         

                        I hope this information is usefull and to hear back from you. Thanks a lot for all the effort.

                         

                        Michel
