Hello,

I have a sound problem on my Dell laptop,

since I updated Windows, I have no sound and in the taskbar, I see the message "no devices found,"

my laptop is the Dell Latitude 7400, I use Support Assist to update the drivers, and the audio driver is properly installed.

I even uninstalled the audio driver that was added by Windows Update and disabled driver updates through Windows, but the thing is that even the driver provided by the manufacturer for my laptop no longer works.

Do you have any ideas to solve my problem please? I am a student and I can't follow my audio and video courses, thank you.

    Hello,

    Windows + R
    Type --> devmgmt.msc and OK.

    Do you have a section --> other devices?
    If so, what is the problematic device?

    What do you have in audio, video and game controllers?

    Also check if there is a device alert in --> System Devices

    ------------------------------------------------------------------------------------

    Still try this driver --> Realtek

    Hello

    Kaneagle, in the Device Manager, I have a section for Other Devices and it's showing Unknown Device.

    And under Sound, video and game controllers, I have Realtek(R) Audio and Intel(R) Sound for audio.

    I installed the driver you suggested, but unfortunately, it still doesn't work.

    I'm on Windows 10, I have the Dell Latitude 7400. I also installed the driver from the official site, but it doesn't work.

      two INTELAUDIO\FUNC_01&VEN_10EC&DEV_0295&SUBSYS_102808E1

      -Intel (R) audio for display >> hardware ID, there are two as well >> INTELAUDIO\FUNC_01&VEN_8086&DEV_280B&SUBSYS_80860101&REV_1000

      Hello

      I deleted the device and restarted the PC but I still have no sound.

      Red cross + message (no audio output device is installed)

      Just to clarify, I have two Windows 10 partitions; on the first one, I have no sound issues because I disabled driver updates in Windows Update, while on the second one, I left them enabled, and that's why I have this problem. I'm trying to tell you that my internal speakers are working properly.

    I right-clicked on the device driver oed... then updated it, I went to the realtekaudio folder, the installation was successful and the exclamation point disappeared from the device, but once restarted I still have no sound and the exclamation point is back on the driver oed...

    I started the sound troubleshooting, still a red cross.

    Perform a Windows repair.
    Check this --> Repair Windows 10 without data loss

    -----------------------------------------------------------------------------------------

    If the repair didn’t work, perform a clean installation of Windows 10.

      I had Windows 10 repaired without losing data and I still have no sound.

      It wouldn't be possible for me to do a clean installation of Windows 10 because I have no way to back up my data.

      I would really like to find a favorable solution please.

      I don't understand, the Realtek driver is properly installed.

      Hello,

      I am getting back to you regarding my ongoing sound issue on my PC.

      I reinstalled Windows 11 from scratch, so it’s a clean installation of Windows. I HAVE SOUND.

      Situation description:

      Step 1: I installed Windows 11 version 22H2 Professional, and I disabled the internet connection so that Windows Update wouldn’t update the drivers.


      Step 2: I disabled driver updates in Windows Update
      as follows:

      Local Group Policy Editor > Administrative Templates > Windows Components > Windows Update >
      Manage updates proposed by Windows Update > Do not include drivers with Windows updates > Enabled
      Then I went to Settings > System > System Protection > Hardware > Device Installation Settings > and I disabled the automatic download of manufacturer apps.


      Step 3: I activated my Wi-Fi.


      Step 4: I waited for Windows to carry out its additional updates, but strangely it also installed the drivers even though I disabled that in Step 2.

      Then the sound disappeared and I have a red cross on the taskbar indicating that there are no output devices.

      The WINDOWS TROUBLESHOOTER tells me (

      Apparently, you don’t have any audio devices connected to your PC.

      Make sure an audio device is connected before continuing.

      )

      even though I just had sound.

      I continue.


      Step 5: I used Dell's tool called SupportAssist and installed all the updates it proposed.

      ... still no sound.

      Step 6: On the Dell website, I installed the previous version of the audio driver but with no result.

      I go to Device Manager and choose the new driver version, I restart with no result.
      I switch back to the previous version also with no result.

      Previous version > 6.0.8940.1
      Latest version > 6.0.9137.1


      Thank you for looking at the screenshots below; you will have all the info regarding the drivers and the details of my PC.

      All drivers are installed except that I have an exclamation mark on a system driver for Intel(R) Smart Sound technology. I will leave you all the screenshots.

      Please excuse me if I'm bothering you; I’ve tried to be as precise as possible.

      And frankly, I can’t format the PC every time, this is the nth time.

      I am eagerly awaiting your help,

      Thank you.

    I selected IntcOED.inf, then unzipped the folder and restarted, but I have no sound.

    I even tried running the installation without unzipping and restarted, but I still have no sound.

      kaneagle thank you for your assistance and the time you spent

      I was able to recover the sound by following the instructions from this link: How to fix "Intel Smart Sound Technology OED" not starting correctly - Appuals.com

      I don't understand why the OED driver still has an exclamation mark, but the sound works fine

      I enjoyed sharing this with you and thank you once again for your effort

      I mark the subject as resolved

    Don't understand??

    The important thing is that it works.

    Have a good day.
