Microsoft Windows 10 (64-bit)

Hello, after a driver update conducted by Avast software, suddenly my computer no longer has audio and does not recognize any internal sound device.  I can hear when I use bluetooth and external headphones. I tried downloading the new drivers from the HP website and then re-started the device, but still no luck. And just discovered the notebook went out of warranty in July. Ugh! Help appreciated!

HI@AJWIND, Welcome to the HP Support Community!


Request you to follow the below troubleshooting steps for Sudden loss of Audio on Windows 10: 


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.
