Hello All.


Troubles with the audio on my HP Notebook.


After a recent Windows update I start having problems with the audio, that is: it sometimes works properly (audio correctly turns on/off by pressing the dedicated button on the top of the keyboard) and sometimes it does not (i.e. pressing the button does not activate/deactivate anything, the red light is on and the audio remains deactivated).


Clues? I have:


- already uninstalled the old driver and reinstalled the new one (found on the dedicated HP section https://support.hp.com/it-it/drivers/selfservice,) - after the identification of my laptop, of course;


- already updated my BIOS (update downloaded from the same section)


Really no idea, when you turn off the machine and then turn on again (or reboot it) the audio can work or can not...


Need help from the experts.


Many thanks!

@gladiatore79 Welcome to HP Community!


I understand that you are facing an issue with the audio.


Do not worry. Let's work together and get this issue addressed.


Please perform the audio test. we would like to confirm the audio card is working properly or not.


1. Power off the PC and make sure that it is completely powered off.

2. Press the power button and the moment you press the power button immediately start tapping F2 key, you should see the system diagnostics screen.

3. Look for the component test, under that all the hardware will be listed, please choose Audio and initiate the quick test.

Note: If it fails it will generate a 24 digits alphanumeric failure id, please capture that.


If the test is passed, perform the below steps.


I suggest you download and run the HP Support Assistant from this Link: https://www8.hp.com/us/en/campaigns/hpsupportassistant/hpsupport.html?jumpid=va_r602_us/en/any/psg/p...


HPSA will automatically search for all the latest drivers for your Notebook


  1. Click My devices in the top menu, and then click Updates in the My PC or My notebook pane.

  1. Click Check for updates and messages to scan for new updates.

  1. Review the list of updates. Updates with a yellow information icon are recommended. Updates with a blue information icon are optional.
  2. Click the update name for a description, version number, and file size.
  3. Select the box next to any updates you want to install, and then click Download and install.

Also, ensure Windows is up to date.


Please uninstall the audio drivers from the device manager and reinstall the drivers.


If the issue still persists, please create the new user accounts and check.
