    Hi Flower_Bud,


    Thank you for your swift reply!


    My product number is 4MW21EA#BCM. I actually had the same issue shortly after I bought the laptop, but I restarted the PC and it worked again. 


    Yesterday I installed some Windows updates and the issue re-appeared. I tried following the guide to uninstall recent updates and uninstalled the sound device, but then, of course, I lose sound completely. When the sound device is reinstalled again, it does not work properly.


    Thank you for any help!


    Cheers :)

    Hi! , Welcome to HP forums.


    I understand you have audio issues with your PC.


    Don't worry I'll try to help you out.


    Did you make any software or hardware changes on your PC?


    Please provide the product number of your PC to assist you better.


    Try the steps recommended below.


    Go to Windows Device Manager > Sound, video and game controllers section.
    In the list of audio device drivers, look for Realtek or IDT High-Definition Audio. This is the device driver for BeatsAudio (a little bit sneaky, wouldn’t you say?).
    Right-click and select Disable. The downward arrow displays on this driver, indicating it is disabled. (NOTE: At this point, you won’t be able to play any music files.)
    Right-click and select Update Driver Software.
    Select Browse my computer for driver software.
    Select Let me pick from a list of device drivers on my computer.
    You should see a window that says Select the device driver you want to install for this hardware. NOTE: If you see a window that says something like This is the best driver for this device, exit the window and repeat steps 4, 5, and 6.
    In the Model box, highlight High Definition Audio Device (this is the substitute audio device driver) and click Next.
    At the Update Driver Warning window, click Yes. You should see a confirmation window with High Definition Audio Device displayed. Click Close.
    In the list of audio device drivers in the Sound, video and game controllers section, you’ll notice that the High Definition Audio Device now displays instead of Realtek or IDT High-Definition Audio.
    At the prompt to reboot, click Yes.

    If the issue still persists try the steps recommended below.

    background intelligent transfer service (BITS) transfers files (downloads or uploads) between a client and server and provides progress information related to the transfers. If the BITS service is turned off, windows update may have problems delivering files to your computer.


    Start the BITS service click start, and then click run.

    Type services.msc in the open box and then click ok.

    Right-click background intelligent transfer service, and then click properties.

    On the general tab in the startup type box, click Automatic, and then click apply.

    In the service status section of the properties dialog box, verify that the BITS service is started. if it is not started, click start.

    Click apply, and then click ok.

    Restart the computer.


    If the issue still persists after trying out the steps try the steps recommended below.


    In Windows, search for Command Prompt. In the search results, right-click Command Prompt and select Run as administrator. Then click Yes.
    In Command Prompt, type sfc /scannow. Make sure to include the space between sfc and the /.
    Press Enter and wait while System File Checker scans for corrupted files.
    When scanning is complete, the results are displayed on the screen.
    If the file checker found and replaced any corrupted files, restart the computer and check the performance.
    If the file checker did not find any corrupted files or found corrupted files but could not replace them, go to the next step.
    If System File Checker finds corrupted files but cannot replace them, use the Deployment Image Servicing and Management (DISM) tool. DISM checks the corrupted files; then downloads and replaces the files using Windows Update.
    In Windows, open a web browser.
    You need to be connected to the Internet to use DISM.
    In Windows, search for Command Prompt. In the search results, right-click Command Prompt and select Run as administrator. Then click Yes.
    In Command Prompt, type dism.exe /Online /Cleanup-image /Restorehealth. Make sure to include the space before each / in the command line.
    Press Enter and wait while DISM works. This might take several minutes.
    If DISM finds corrupted files, it replaces them using Windows Update. If this occurs, after DISM is finished, restart your computer and see if the performance has improved.


    Also, uninstall the audio drivers from device manager and install the latest audio driver on your PC using HP support assistant.


    Refer this article to know more information about using HP support assistant.


    If the issue still persists uninstall the audio driver from the device manager and install the drivers using HP recovery manager.


    Refer this article to know how to restore drivers using HP recovery manager.


    If the issue still persists try running a system diagnostics test from your PC and check if the hardware components on your PC are functioning correctly.


    Refer this article to know more information about running system diagnostics on your PC.


    Let me know if this works!

    Have a great day! :)

    Hello everyone! I just recently purchased my HP Pavillion Laptop in September and I had no issues at first... Then I started noticing the screen kinda swivels backwards on its own, it's almost like it's top heavy. So with the slightest push, the screen moves back. I figured since it's a convertible it wasn't a big deal BUT there is a major audio issue..

          A couple days ago, I was listening to music on YouTube while multitasking on Microsoft Word, but suddenly the music stopped playing on it's own. I went to the YouTube page and realized it was actually still playing on the browser, but there was no sound coming out of the speakers.

         Nothing was coming out of the speakers. I reset the computer once, nothing. Twice, thrice, still nothing. I tried troubleshooting with no luck either. I'm guessing this is a manufactering error because this is only a month old laptop, straight out the box. I don't know what to do...

    I tried to do this, but my laptop doesn't have the file its telling me to click on

    audio probs.pngi'm not sure what to do about this. I'm not very tech savvy and so I don't know if it's just named something different in my files or if it really just isn't there.

    That didn't solve the issue for me unfortunately, and its not saying 'No Audio Output Device'. It literally just stopped putting out sound on Friday afternoon, and I don't have the SST driver referenced in the solution.

    There is no apps running that im aware of. Dont know how to see apps running in background, but not sure. Would have seen it already. The volume button is on 100 but the sound is much fainter then what it would normally be. It seems to be a video from youtube.

  • 10/23/18--19:14: HP Audio Switch Missing
  • After upgrading to Windows 10, version 1809, My HP Audio Switch is missing, Where do I go to reinstall it? It is not showing up in my Dashboar on the HP Driver Support Website under Audio or the Software tabs.

    0 0

    I manage to get it working without updating the BIOS - reinstalling the audio driver from HP and running component test in the BIOS.  We'll see how long it lasts.

    Go to  msconfig.exe, then click on the Boot tab.

     Click the Advanced options button, check the Maximum memory box and set the value to maximum, and restart the PC.

    No improvement in my case.

    Thank you for responding,

    It's great to have you back ;)


    Do you experience the same sound quality issue when headphones are plugged in? 


    Let's try these steps: 

    Open Bang and Olufsen audio app and enable Equaliser. For more information, you could refer to this article: Click here


    If the issue persists, let's uninstall and reinstall Audio drivers once again following these steps: 

    1. Press Windows +X to open the menu, and choose Device Manager on it.

    2. In device manager, expand category “Sound, video and game controller”.

    3. Under this category, right click on your Audio driver and click on Uninstall.

    4. You may be required to confirm the uninstallation. Check the box next to “Delete the driver software for this device” and click OK button.

    5. Restart your PC for the change to take effect. After restarting. Windows will attempt to reinstall the driver.

    6. Do not perform any manual upgrades to the driver until it does automatically.

    Let me know how this goes,

  • Hi:


    Many newer HP notebooks lost the audio recently, due to a windows update.


    The only suggestion I can offer would be to see if either of these links are of help to you.

    The sounds was fine the other day and now I don't have any sound when trying to watch a video. 


    I have tried installing older drivers but that hasn't worked.  Tried rebooting many times but still have the same issue.  It seems to be an issue with the Conexant driver.  I have a feeling that the driver was updated during the last windows update. 


    I am not sure what else to try.
