Sound is going up and down on laptop

HP Recommended
HP Pavilion 15z High Performance
Microsoft Windows 10 (64-bit)

Hey folks,


When i try to use anything that has sound on the default speakers of this laptop the sound drops in and out. This leads me to believe that the speaker is not in fact damaged, but that something is making it sound too quiet and then too loud.


The sound is on one hundred. This does this on any app, program or webpage. It is quiet most of the time and then experiences spikes in sound that would be the normal sound when the device is on volume 100. 


I did turn off the signal enhancements> enable audio enhancements and there was no improvement. 


Drivers are updated, computer is updated. 


Let me know what other information is pertinent.

 @malz422 I have a few steps that should help resolve the issue:

  • Windows Audio is a Windows service that manages audio for Windows-based programs. If at all this service is stopped due to any reason, audio devices will not function properly.
    To fix audio services, open the run command and launch services.msc.
  • In the services window search for Windows Audio and right-click on it to select Start to start the audio service.
  • And ensure the Startup Type is set to Automatic.
  • Click Apply and OK.

Restart the computer and check if it works.

If the issue persists, try the steps mention on this link: Click here


Also, let's run a test on your device to identify if this is either a hardware or a software malfunction?

If not, let's start with that:

  • Turn the computer On and keep tapping F2 repeatedly on startup to enter system diagnostics. 
  • Select the component test and run a Audio test on your computer. 
    • (By the end of this article all the issues should be resolved)

If the test fails or does not detect the wireless card, this could be a hardware malfunction, please revert to me with the failure ID,
