@CatPearson94
Thank you for posting on the HP Support Community.

 

Have you made any hardware/software changes?
Have you tried any troubleshooting steps?
Did this happen after a recent window or software update?

 

I have a few troubleshooting steps we could try to fix the issue:  

Firstly, BIOS Defaults - (After hard reset follow the below steps while starting the computer)
1) Shutdown the computer. 
2) Turn the computer back on again and repeatedly tap on the ESC until a Startup menu appears. 
3) Press F10 once for BIOS. 
4) Press F9 for BIOS defaults. 
5) Press F10 to save and exit.
If the issue persists, continue the next step,

 

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:

  • In Windows, type find and fix audio into Search, or right-click the speaker icon https://hp.dezide.com/data/pictures/hp-external/web_author/guid-a7774d00-7a27-4b96-ab1c-b2f8a7083ba0-low_86905_en.jpg in the taskbar and select Troubleshoot sound problems.
  • Select Find and fix audio playback problems or Find and fix audio recording problems from the Search results.
  • Click Next.
  • Select the device you want to troubleshoot and click Next.
  • Wait while the troubleshooter detects problems and makes changes (or prompts you to make changes).
  • When the troubleshooter is done, the Troubleshooting has completed page is displayed, listing any problems found and what changes were made to the computer.
  • Click Close.
  • If a recommended action is displayed, select Apply this fix.

Restoring the audio driver in HP Recovery Manager:

  1. In Windows, search for and open Recovery Manager.
  2. Click Reinstall drivers and/or applications.
  3. Select the audio driver in the list, and then click Install.
  4. Wait for the driver to reinstall. When the installation is complete, click OK.
  5. Close HP Recovery Manager and then restart your computer.
  6. Test for sound. If the audio problem persists after reinstalling the driver, try updating the driver using Device Manager.

Updating the audio driver using Device Manager:

Make sure the audio device is enabled and then update the audio driver using Device Manager as follows:

  1. In Windows, search for and open Device Manager.
  2. Double-click Sound, video and game controllers.
  3. If a sound device is listed with a down arrow, the device is disabled. Right-click the sound device name and select Enable to re-enable the device.
  4. With the sound device enabled, right-click the sound device and select Update Driver Software.
  5. Click Search automatically for updated driver software.
  6. Windows checks for and installs any updated drivers found. The window displays whether the computer already has the latest available driver or if Windows was able to successfully update the audio driver.
  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.
  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.
