  14. I have a Dell XPS Gen 4 that had Vista on it. I wiped all partitions and installed Windows 7 Ultimate 64 bit. I have this same issue saying no audio output device is installed. When I bring up the device manager, it does not even have the list “Sound, video and game controllers”! However, under “Other devices” Multimedia Audio Controller and PCI Input Device show up with errors. It will not find any drivers when I opt to and uninstalling them and rebooting does not resolve the issue either. Any suggestions?

    1. Hi Arsene,

      Have you tried using Driver Easy to update the drivers? If you have, the issue might not be caused by faulty drivers. In that case, please send us more details about the problem. We would help investigate the issue further. You can send us the information using Driver Easy Feedback tool.


      1. After doing all these steps, my speaker problem is still there. I even updated the drivers, formatted my system and uploaded new windows, but in vain. Is there any hardware problems with my system like Speaker Chips are dead or my speakers of system are dead? Kindly solve this problem.

  15. Hi there, don’t know if you can help, but I just purchased a new computer and did not realise it did not support XP.

    The motherboard disc would not install (OS not supported) I’ve installed XP, and it all works apart from the sound and the upper 2 USB sockets at the rear. I’m not too bothered about the USB sockets as I have already put an old USB from my dead computer into the motherboard, and also got a 4 USB extension. I don’t use the sound too often but it would be nice to have it.

    The motherboard is ECS A68F2P-M4 (Elitegroupe)

  16. i have no audio ,video and game controllers on my pc

  30. I had the same issue; when trying to fix the probable driver issue, came across Network Controller driver which was showing code 28 error. On fixing(downloading the proper driver) this network Controller driver issue, my audio driver was fixed automatically, i.e, the Realtek High Definition Audio driver was automatically installed.

  31. thank you for your heelp

    but when i tried to follow those steps it only shows me ”’HELP”’ and not as you said it will show add legacy hardware


      If you only see ‘Help’ there, please click the blank place of the list pane then click ‘Action’ again.

    1. Dear ngomuo,

      You can use Driver Easy to scan your computer and download the latest Realtek HD audio drivers.

  32. Omg thank you so much! My son bought a Surface Pro 4 and we had a red x by the speaker button. I think he inadvertantly took the hardware off the tablet trying to fix it. I downloaded the software (I went ahead and bought it), used it to scan his tablet and fixed everything in about 2 minutes!!!

    1. Coucou Babeth !!Oh oui quelle magnifique aventure !!! Nous sommes vraiment heureuses d&ai217;#vo8r fait votre connaissance ! Des moments à jamais gravés dans nos coeurs !!!!Très gros bisous et à très bientot !!!!Sandra

  33. hi ,
    i tried using above details, but after installing the same message is coming as ” this device could not work properly” code error 10.

    1. Dear Abhishek Singh,

      The code 10 error might be caused by driver issues. Have you try using Driver Easy to update drivers?

    1. used the procedure stated above… but when installing the realteck driver I get “extended attributes are inconsistent” .. any suggestions? All this happened after a crash and recovery using acronis with a new harddrive

  34. By installing realtek drivers, my problem( Red cross on audio button) solved….
    but after every restart again this problem occurs.
    kindly tell about this

  35. I did not have the red x, but it did show that no audio device was found. I followed all the steps and put in the generic device since I had no clue which to pick. I did notice that the generic device was the only one that was supported. I was then able to update all my drivers. After restart, everything came back on line. Thanks for the help.

  36. Had this problem, checked loads of websites, what worked for me is:
    1. Go to device manager, and uninstall all drivers/hardware devices under sound video and game controllers
    2. Restart your PC, there should be a red cross next to the sound icon on the start bar
    3. Go to device manager again, and follow the steps above to reinstall your drivers and hardware devices
    4. Restart again and it should be up and running again
    Btw dont ask me for any other help i dont really know what im doing just stumbled into this, just thought if it does fix it then great

  37. There is NO “Add Legacy hardware” under “Action”, only a “Help” option. Your statement is invalid. NEEDS TO BE UPDATED!!!!

    1. Dear Customer,

      If you only see ‘Help’ under this option, please click the blank place of the list pane then click ‘Action’ again.

  38. There is NO FIX FOR THIS!

    I’m a network engineer and upgraded to 10 3 separate times to give a chance and High Definition Audio via the HMDI from AMD or NVIDIA cards will NOT WORK!

    You can thank MS for this. It did work after initial release of Windows 10 on Oct 29th but then broke several weeks later and “manual install” of HD audio driver WILL NOT WORK.

    It won’t send the HD audio signals out therefore, if you have a stereo receiver connected to computer HDMI audio/video output, your receiver won’t auto change the DSP to reflect the actual HD audio from said computer (DTS HD Master, Dolby TrueHD, etc)

        1. Dear Jack,

          If you don’t see “Sound, video and game controllers” in Device Manager, please follow step 3 to Add Legacy hardware.

  39. In sound u have 3 options nvidia HD audio, nvidia virtual audio, and realtek HD audio but showing with “!” Yellow color sigh

    1. Dear Prateekgavaskar,

      If the device shows with “!” yellow sign, there is problem with the device driver.
      To fix the problem, try updating the drivers. You can use Driver Easy to help you.

  40. after i did all the steps i still see the same error .. and when i opened the device properties the device status says * This device cannot start. (Code 10) *
    what shuld i do next??

  41. Hi after i instill driver i got to playback secession i found no speaker there how should i know that my pc speaker is missing or broken?

  42. Hi camilla,
    In step 8, I do not see that option “Realtek”.Even I tried driver easy.It didn’t work please help me

  43. hi im using asus,windows 10.I already followed the steps given and even use the driver easy.However,the issue still persist.No audio output is installed

    1. Dear Roger,

      Please try uninstalling the audio driver and using Driver Easy to update the drivers again.

      If the problem persists, it might not be caused by driver issues.

  44. Dear sir,

    I have downloaded realtek high definition audio for installing in my system, but when I try to install it manually a new page opens with a list of program files instead of installing the device. Please let me know the next steps shows how to install it manually.

  45. any time i boot my machine i get non audio is installed why
    but unless i restart the machine for several time
    pls dont no wat to do

    1. Hi naiman,

      If you are not using Realtek audio card, you won’t see Realtek there. Please identify the sound card manufacturer.

  46. When I select ‘Action’ from the menu, there isn’t any ‘Add Legacy Hardware’ option. The only option is ‘Help’?

  47. I get the following error message when i install the realtek driver “Extended attributes are inconsistent” .
    How can i solve this?

    Thanks in advance
