HP Notebook PCs - No Sound or Distorted Sound from Speakers (Windows 10)
This document applies to HP and Compaq notebook computers with Windows 10.
Follow the steps in this document to resolve audio issues on your laptop if there is no sound coming from the speakers, or if the sound is muffled, intermittent, crackling/popping, or otherwise distorted.
Before you begin: Restart the computer
If there is no sound coming from the speakers or headphones on your computer, the issue might be caused by an application controlling that device and preventing other applications from using it. Before attempting the other troubleshooting procedures in this document, restart your computer, and then test the audio to see if the problem is fixed.
Step 1: Use the troubleshooting tool in Windows
The audio troubleshooting tool in Windows can automatically fix common audio recording and audio playback problems with your computer. Run the troubleshooting tool using the following steps:
  1. In Windows, type find and fix audio into Search, or right-click the speaker icon in the taskbar and select Troubleshoot sound problems.
  2. Select Find and fix audio playback problems or Find and fix audio recording problems from the Search results.
  3. Click Next.
  4. Select the device you want to troubleshoot and click Next.
  5. Wait while the troubleshooter detects problems and makes changes (or prompts you to make changes).
    Figure : Detecting problems
    The troubleshooter detecting audio problems
  6. When the troubleshooter is done, the Troubleshooting has completed page is displayed, listing any problems found and what changes were made to the computer.
     note:
    For detailed information about the troubleshooting, click View detailed information in the troubleshooter window.
    Click Close.
    Figure : Troubleshooting completed
    Troubleshooting completed
  7. If a recommended action is displayed, select Apply this fix, or Skip this step to continue to search for other problems.
If the audio problem has not been resolved, continue to the next step.
Step 2: Test external speakers or headphones
If you are using external speakers, they might be faulty. Try using another set of speakers, or a pair of headphones, with your computer. If the second set of speakers or headphones produces sound without problems, the first set of speakers is faulty.
If the same audio problems are present in both pairs of speakers or headphones, continue to the next step.
Step 3: Set the default audio device
After using the troubleshooting tool, make sure your desired audio device is set as default:
  1. In Windows, type sounds into Search. Select Change system sounds in the Search results.
    Alternatively, right-click the speaker icon in the taskbar and select Playback devices.
  2. In the Sound window, from the Playback tab, select your playback device, then click Set Default. If only one playback device is listed, it is set to default automatically.
     note:
    If you are having problems setting an HDMI audio device as the default playback device, refer to Troubleshooting HDMI Display and Sound Issues.
    Figure : Set Default
    Set default playback device
    If you set speakers as your default device, proceed to the next step.
  3. With the default playback device selected, click Configure.
    Figure : Configure default playback device
    Configure default playback device
  4. Click your speaker setup in Audio channels.
     note:
    If you want to use HDMI output, select Digital Audio (HDMI). For more information, refer to Troubleshooting HDMI Display and Sound Issues.
  5. Click Test to send sound to each speaker, or select an individual speaker to send sound to that speaker.
    Figure : Test Speakers
    Speaker test screen
  6. If sound is heard correctly from each speaker, you are finished.
    If sound is missing from all or one of the speakers, or if the configuration type was changed, continue with speaker setup by clicking Next. Follow the on-screen instructions to complete the speaker setup.
    Test for sound. If sound problems persist, continue to the next step.
Step 4: Restoring or updating the audio driver
If your computer came with Windows 10 installed, restore the original audio driver using HP Recovery Manager, or update the driver in Device Manager. If you upgraded your computer to Windows 10, update the audio driver in Device Manager.

    Windows has successfully updated your driver software
  7. If a window opens asking you to restart the computer, restart the computer.
  8. Test for sound. If the audio problem persists after updating the driver, continue to the next step.
If you completed these steps and the latest driver was already installed, use the following steps to uninstall and then reinstall the driver:
  1. In Windows, search for and open Device Manager.
  2. Double-click Sound, video and game controllers.
  3. Right-click the sound device and select Uninstall.
    Figure : Uninstall driver
    Uninstall the audio driver
  4. Restart the computer to reinstall the driver.
  5. Test for sound. If the audio problem persists after reinstalling the driver, continue to the next step.
Step 5: Perform a hard reset
Try a hard reset to resolve audio issues on your notebook. For instructions, see Performing a Hard Reset.
If the hard reset did not resolve the audio issue, continue to the next step.
Step 6: Reset BIOS to defaults
Accessing the BIOS Setup menu
There are at least three different ways to access the BIOS setup menus depending on the type of CPU, the BIOS, and when the notebook was built. For most models, after you press the power button to turn on the computer, a prompt displays specifying which key to press to enter BIOS or Windows or diagnostic functions. For newer computers, it will be the F10 key or the Esc key. On older computers, you might be prompted to press the Delete key to enter a Setup function. If you do not press the suggested key at the proper time and the computer continues through the boot process, shut down the computer and try the procedure again.
  • Pre-UEFI, before 2008
    With the computer turned off, press the power button to turn on the computer, and repeatedly press the F10 key. The HP or Compaq logo screen prompts you to press F10 to enter the BIOS.
  • UEFI-enabled, 2008 to mid-2011
    If the computer has the UEFI pre-BIOS environment, when the HP or Compaq logo screen displays, you are prompted to press Esc to enter Startup Menu. Then press F10 to enter the BIOS Setup.
    With some configurations it might be possible to turn on the power and press F10 to access the BIOS without going through the UEFI Startup Menu.
  • Shortened Startup without logo screen, mid-2011 or later
    To help computers start faster, on some models the HP or Compaq logo screen is not displayed during the startup process. In this case, after pressing the power button, repeatedly press the Esc key to enter the Startup Menu, and then press F10 to enter the BIOS Setup.
Reloading the default settings
Complete the following steps to reload the factory installed BIOS Setup settings:
  1. In the BIOS Setup utility, select the Exit tab.
  2. Select Load Setup Defaults.
  3. Select Save Changes and Exit.
  4. Press Esc and then Enter to exit the BIOS.
    The default settings are restored, the BIOS Setup utility closes, and the computer starts into Windows.
If the audio issue persists, continue with the next step.
Step 7: Run the Audio test from the HP PC Hardware Diagnostics (UEFI)
The Hardware Diagnostics Audio Playback Test checks your system to make sure the audio device is functioning properly and tests the functionality of the audio subsystem, including audio controllers and codecs.
 note:
HP occasionally makes updates to its HP PC Hardware Diagnostics (UEFI) environment. To download the latest version, go to the HP Hardware Diagnostics website. For more information about installing and using the HP PC Hardware Diagnostic tests, see Testing for Hardware Failures (Windows 10, 8).
Use the following steps to run the HP PC Hardware Diagnostics (UEFI) Audio Test. During the test, a few music notes are played in sequence and then repeated. This test takes 1 minute to complete for each audio output port.
  1. Hold the power button for at least five seconds to turn off the computer.
  2. Turn on the computer and immediately press the F2 key repeatedly, about once every second.
  3. The HP PC Hardware Diagnostics (UEFI) main menu is displayed. Click Component Tests.
    Figure : HP PC Hardware Diagnostics (UEFI) main menu

  4. The Component Tests menu displays. Click Audio.
    Figure : Component Test menu with Audio selected

  7. During the test, a few music notes will be played in sequence and repeatedly. Listen carefully and select the number of notes you hear in the sequence. If you enter a tone number incorrectly, run the test again. If you hear nothing, select No sound.
     note:
    Some HP models have a Volume control in the test window. Make sure you increase the volume level before making a music tone selection.
    Figure : Entering the number of notes
    Entering the number of notes
  8. When the Audio Test is complete, the results are displayed on the screen.
    If the audio test passes, return to the Main menu to exit and restart the computer.
    If the audio fails the tests, a failure ID will be provided. Write down the information so you have it available when you contact HP Customer Support. The information is also available in the Test Logs, on the Diagnostics UEFI main page.
    Figure : Audio test results
    Audio playback test results
If the Audio Playback Test passed without errors but the audio problems are still present, continue to the next step.
Step 8: Update the BIOS
Updating the BIOS can resolve some audio issues. For instructions, see Updating the BIOS.
If updating the BIOS did not resolve the audio issue, continue to the next step.
Step 9: Restore or reset your computer
If you have tried the troubleshooting steps and your sound is still not working properly, try restoring your computer. Computers that had functioning sound in the past can be restored back to that point. Use the steps in HP PCs - Using Microsoft System Restore (Windows 10, 8) to restore all the system files back to a time when the sound was working properly.
Alternatively, reinstall the operating system by performing a push-button reset. For instructions, see HP PCs - Microsoft Push-Button Reset (Windows 10).
Step 10: Perform an HP System Recovery
If you have tried the troubleshooting steps and your sound is still not working properly, perform an HP System Recovery. For instructions, see HP PCs - Performing an HP System Recovery (Windows 10).
 note:
If you upgraded the operating system on your computer, an HP System Recovery will restore the original version of Windows.
