Troubleshooting: how to install the Microsoft HD Audio class driver


Most on-the-motherboard audio devices support the Intel High Definition Audio standard.  Windows Vista (and later) includes a “class driver”, hdaudio.sys, which should work with any such audio device.

Usually systems come with a vendor-supplied driver installed.  This driver is designed specifically for the hardware it runs on (as opposed to being designed to the standard) and so it comes with additional functionality.

Occasionally, for troubleshooting purposes, it is useful to switch from one driver to the other… either to get the additional functionality provided by the vendor-supplied driver, or to see what happens if the class driver is installed.

Here’s how to switch back and forth.

Click “Start”.

Type “devmgmt.msc” (without the quotes) to launch Device Manager.

Expand the “Sound, video and game controllers” node and note the list of audio devices.  In this case, I have one audio device, and by the “High Definition Audio Device” name I deduce that I have the class driver installed.  (If the device name included a company name, I would infer that I had a vendor driver installed.)

Right-click the device you want to change the software on.

Windows offers to automatically detect the driver that should be installed.  No thanks, we want to pick a particular driver:

Windows asks where we want to look – do we have a set of driver files, or is the driver already in the list of installed drivers?  In this case, we want to look at the list of drivers for this hardware that are already installed.

Windows shows us a list of drivers that are already installed and usable for this hardware.  At this point you would expect to see two drivers listed: the vendor driver, and “High Definition Audio Device.”  (When I made this blog post, I was lazy, so I didn’t bother to make a screenshot that showed two drivers.)

To install the class driver, pick “High Definition Audio Device” and click “Next.”

“High Definition Audio Device” is a class driver, so you get this warning.  Click “Yes.”

Windows does its thing…

… and eventually tells you that it’s done.  If your audio device was in use, you may get the “you have to restart” message.  Regardless, click “Close”.

If you got the “you will need to restart” message, Windows helpfully offers to restart right away.

Make sure you’re ready for a restart (no unsaved documents or anything) and restart either by clicking “Yes” or by using the Start menu.

When you’re done experimenting, you can go back to the vendor-supplied driver by going through the same steps and choosing the vendor-supplied driver in the list of drivers.

    i need aad ki coode for my receiver class hd 2010 plus            my id cood m.riaz1979@yahoo.com      please help me

  2. James O'Shay says:

    Hey Matt!   It worked! (sorta). I now have sound. Thank You!

    following your tutorial restored sound to my aging P C.

    Alas, sound card with this driver does not recognize the on-board mics.

    Recording devices/recording tap shows "microphone not plugged in".

    "show disconnected / disabled devices" are both checked.

    No other devices are listed.

    Thank you Matt.

  3. Woodjack says:

    Terrific! Got sound back on my ancient HP Pavilion dv2500!

    Thanks so much

  4. Maurits says:

    @Woodjack: http://support.hp.com has a Conexant HD Audio driver for the HP Pavilion dv2500. It might be worth a try to download and reinstall that.

  5. James O'Shay says:

    Hello.

  9. Anders Larsson says:

    I succeded to reinstall my HDAUDIO driver again after having uninstalled it because it did not work. The original driver was system speaker but it used the microsoft driver And it did not work. I do not know when it stopped working. But It must have been some Microsoft update i guess. Now it is not called System speaker any more so now it is only the Microsoft HDAudio driver

  10. KJ says:

    Thank You. This made it work like new…

  11. Dalton says:

  17. loly says:

    THANKS A LOT!!!!!!!!!

  18. Jim says:

    Worked for me also.  I upgraded a 8.1 computer with no problems.  I did my 7 computer which I thought had identical hardware (it did not), no sound.  Your solution did the trick.  THANKS.

  19. Mirza says:

  21. Pradeep says:

    Hey Matt…….it worked.

    Thanks a ton.

  22. jbnimble says:

    Matt,  I got the sound back.  Evidently Realtek does not have a workable driver for sound.  The microsoft driver at least gets the sound back.

    Many thanks!

    jbn

  23. brian says:

    fixed it first time. very helpful very easy to follow. idiot-proof a.k.a. me-proof

  24. No sound from speakers says:

    This worked if I connected the TV via HDMI socket but not through my speakers.   Anyone got a solution.  Every time I plugged my external monitor in it resorted to HDMI jack.

  25. Mike says:

    Worked.  Thanks!

  26. SDM says:

  44. Ravi says:

    Worked for me on Sony E series. Thanks a lot.

  45. Elaine says:

    Was getting really annoyed and trying lots of different ideas from web and then came across your post.  And yes it worked… brilliant I have sound at last.  Thank you so much.

  46. Graham Peacock says:

    Just got around to trying this 'fix'on my Dell laptop with Windows 10 recently installed. Microphone not working since the Upgrade, so desperate to try anything at the moment.  Result, failed.  My voice on a test message can just be heard at full volume, but not good enough to use in a (say) Skype conversation.  Any further suggestions?

  47. Bero says:

    It didn't work with my windows :(

  48. Bruce says:

    Sorry Matt to be an odd one out, but I followed your plan and re-started my PC. Unfortunately, on both my Realtek driver and your AMD HD Audio Device when I try to play a CD., I get no sound, but a little icon keeps on darting through the 14 tracks – that is using my Windows Media Player! Any ideas please?

  49. Michel M. says:

    Thank you very much for this!!! Sound is back :)

  50. bryan says:

    tried but no joy .

  54. Augustus Nnaji says:

  55. lile says:

  57. Gary B says:

    I can't tell you how happy I am now that I've found your blog and YES it works. I have sound and it took less than 5 minutes. Thank you and I also saved $69.99 the Geek Squad was going to charge me to diagnose the problem and then a additional fee to fix the problem. Your blog, PRICELESS!!!

  58. James says:

    Thanks very much your advice worked a treat!

  59. sanjeev says:

    Hi Matt,

    Thank you very much for your help…. it worked for me.

  60. BigMackTech says:

    Had problem with Windows 10 Audio worked for the first 4 days and then just stopped.  Updated Driver didn't work, but this did.  Thanks for the info.

  61. Daysha says:

    Thank you very much this was so helpful and fast!

  62. Shah says:

    that was very helpful mate cheers

  63. Mark says:

    Thank you so much!  My Asus Laptop with VIA Audio is now functional again.  Speakers and 3.5mm jack all working.  Sound quality isn't as good but it works!

  64. T says:

    Thank you! It worked. I've just installed Windows 10, and like many other people, the sound wouldn't work with either of the vendor-supplied drivers, even updated (why is this? It seems shady; there's a reason I bought this particular computer with its particular features like sound and graphics). At least now I can hear! Thanks.

  65. jazmín says:

    wow, thank you

  66. M.Muller says:

    Hi Matt,

    Thank you for the great tutorial. I found it most helpful when upgrading from Windows 7 and installing the necessary driver to get my sound working on my HP Envy-15t. Have a question, even though the sound works, after installing Windows 10 I have noticed a substantial reduction in volume from my speakers. Is there a way to fix this?

  67. JeanniS says:

    I can't figure out how to get to device manager.  If I can't do that I can fix it.

  68. ozinnz says:

    So very clear to understand and it worked (no sound after upgrading to windows 10). Thanks

  69. Spencer says:

    This didn't work for me. I have the same situation with no sound. My computer is only a year old as well.

  70. Sean Liming says:

    Upgrade to Windows 10. System has multiple audio outputs, and the update switch to the one I am not using. Change the sound control panel settings and got audio working again.

  71. Lamont J W1701 says:

    This FIX works as stated for me.  Much thanks, after all what good is Multimedia without the Audio.

  72. Jan Schmidt says:

    Thank You :)

  73. miskin batcha says:

  87. Tim Steinkamp says:

    Very frustrating as my problem is not addressed which is sound from the browsers and test buttons but not from VLC or Windows Media Player.

  97. Penny says:

    I'm so relieved – I got speaker sound back on my Dell N5010 (Intel i5) after it suddenly stopped working yester. I've had windows 10 for a month or so now so I'm not sure if it's related, but I need audio for my work so I was very pleased to see that this solution has worked to resolve the issue.

    Thanks!

  98. James says:

    Have done exactly as above,but it gives me error code 39

  99. Sebastian says:

  119. Soo says:

    Windows 10 has just installed lengthy updates (had at least two coffees while waiting). As a result there was no sound.
    Followed your clear instructions and all is right again. Many, many thanks. x

  120. Artur says:

    Thank you so much! It worked so nice :)

  121. Darren says:

    Since upgrading to Win10 on my Asus N55SL, I have had no sound via the speakers, only the headphones. Many months of searching and following so called fixes bear no fruit. This however, did the trick.

  122. JAYTEE says:

    THIS WORKED THANKS

  123. Jay Bry says:

    Thank you so much! The audio is FINALLY fixed on my Windows 10 computer!

  124. Stefan says:

    You saved my day! Thank you!

  125. M kirk says:

    I had to right click and delete my driver and then I had to rescan my computer for an audio device. It recognized and reinstall the driver and it then started working. It’s an old school work around Microsoft……..and it still works 20 years later. I just had to learn the windows 10 version of doing it. Always the fun of a new OS, how to fix old problems in a new format. When will they learn? Never…..

  126. Marc says:

    Same issue as listed. The fix doesn’t work though because I don’t have Sound, Games and Video Controllers in my devices / drivers list so can’t choose it. I was told to reset my Windows so backed up and reset but still not fixed. PC is Asus X555L. Help!!!

  127. @Marc download your audio drivers from Asus’s support site: http://www.asus.com/US/Notebooks/X555LA/HelpDesk_Download/

  128. Ralph Higginbotham says:

    My hardware will not start after installing the new drivers. Whats next?

  129. walldez says:

    THANKS A LOT! I WAS ABOUT TO GIVE UP. YOU’RE GOOD.

  130. yelo says:

    thank u…may God bless u

  131. bob buyers says:

    thanks for instructions – hit dead end: “this device cannot start. (Code 10) ” “If you know the manufactuer of your device you can visit its website and check the support section for driver software — CLOSE
    “”

  132. Jode says:

    Thank you! Worked for me, after hours of reading and troubleshooting. Bless you. Whew. The sound got goofed up after I upgraded (my perfectly fine) system from Windows 7 to Windows 10 on a machine with Soundblaster – which doesn’t work. At least I have sound.

  133. COREY LAROCCA says:

    Thank you so much!
