    NUC7i3BNK - Broken PCM sound from and above 88.2/16 via HDMI

    obladi

      Hi

       

      No issue with DTS_MA (96/24) and with other encoded HD format but sound in case of PCM from and above 88.2/24 is broken more and more as quality is higher and higher.

      It is same problem with Direct Sound and WASAPI, with foobar2k and Jriver and Kodi.

      I tried latest three Intel Audio Drivers but problem is same.

       

      win64_154518.4664.exe

      GFX_WIN10_64_15.46.5.4771_BN.zip

      GFX_WIN10_64_win64_154702.4815.zip

       

      DAC is Pioneer Receiver SC-LX 59 which is working fine from other sources via HDMI too.

      OS: Win10pro 1703

       

      Update: I have tried over all HDMI port on the receiver. Surprisingly only 4K HDCP2.2 port were effected. I would emphasize that other sources can drive these ports too without issue.

          Hello obladi,

          Thank you for contacting Intel® technical support.  I will be more than happy to help you.

          I understand that you are having issues with the sound on an Intel® NUC Kit NUC7i3BNK.

          To better assist you with your request, I will need to check some more information.  Please let me know what is the name of the software that you are using to test the audio and to confirm that the audio is broken from and above 88.2/16, and let me know how is the issue happening so we can try to replicate it in our labs.  Also, if possible upload a file with this issue to a file sharing service so I can download it and use in my lab test.

          Regards,

          Xavier A.

                Hello obladi,

                Thank you for your patience.  We were unable to replicate the issue with the latest driver version, which was recently released on November 7.

                I would recommend you to manually clean install the latest driver and test again to see if the issue was fixed with the update.  First, you will need to uninstall and delete the driver in your system, and then you can proceed to manually install the latest driver,

                Please follow the steps below to uninstall the graphics driver:

                1. On the keyboard, press WinLogo key + R, then type in devmgmt.msc
                2. Expand the Display Adapters section.
                3. Find the Intel® Graphics Driver. The driver can also be called the Intel® Graphics Media Accelerator Driver (Intel® GMA Driver).
                4. Right-click the Intel Graphics Driver and select Uninstall.
                5. Select the check box Delete the driver software for this device.
                6. Reboot the computer after the uninstall process has finished.
                Please follow these steps in order to update the graphics driver:
                1. Download the graphics driver ZIP file: https://downloadmirror.intel.com/27266/a08/win64_15600.4849.zip
                2. Unzip the file to a designated location or folder.
                3. Right-click Windows Start icon and open Device Manager.
                4. Click Yes when prompted for permission from User Account Control.
                5. Expand the Display adapters section.
                6. Right-click the Intel® graphics entry and select Update Driver Software.
                7. Click "Browse my computer for driver software".
                8. Click "Let me pick from a list of device drivers on my computer".
                9. Click "Have Disk".
                10. Click "Browse".
                11. Access the designated location or folder, and access a folder called "Graphics".
                12. Select the file called "igdlh64" or "igdlh".
                13. Click Open, then click OK, and finally click Next. Drivers are now being installed.
                14. Reboot your computer.
                If this process does not fix the issue, then we will need to escalate this issue to the next level of support.  If that becomes necessary, and if you have confirmed that the latest version does not fix the issue, per procedure to escalate the issue, please follow the next link to find a table.  Reply to this post and add that table answering all the requested information.

                  Thanks for your reply Xavier. I did the following updates.

                   

                  1) I bought a new HDMI cable marked 2.0 on cover. Although my other cables should be 2.0.

                  2) BIOS was updated from 52 to 54. It didn't helped.

                  3) HDMI firmware was updated from 1.66 to 1.72. It did't helped.

                  4 I followed your guide is in previous post step by step. It didn't helped.

                   

                  So the root-cause can be due to

                   

                  1. Intel audio driver (HDMI2.0 compatibility)

                  2. Intel HDMI hardware or firmware (I am afraid that the device itself is wrong but proving it to dealer will be a bit difficult.)

                  3. Pioneer receiver HDMI input. (Unfortunately I have only the NUC as HDMI 2.0 source but driving amplifier from any other 1.4 compatible device it sounds good.)
