No audio after 1909 update

[amanevan]

I have recently updated  my laptop (HP Pavilion x360 - 13t-u100 CTO) to Windows 10 1909. Right after updating, I see that the audio output through speakers has been completely lost. I have tried:

- Reinstalling the audio drivers from HP's website. (This process uninstalled the current drivers, rebooted and installed the new drivers).

- Uninstalling the Windows update. My laptop now runs on 1903. 

- Tried Windows HD drivers instead of Realtek driver. Still no luck. 

I can confirm that the audio works fine through Bluetooth speakers/headphones. Windows thinks there are no issues with the driver. I do not see any error message on Windows anywhere. Please let me know what more can be done. 

Thanks!

Hi Kumar, 

Looks like I do not have System Restore enabled on this machine (this is my mom's laptop). I have tried the remaining steps already and here is a brief synopsis. 

Running Find and Fix audio troubleshooter recommends me to 'turn off enhancements' - which does not exist in Realtek's driver. 

I have tried uninstalling Realtek's audio driver to use Windows HD sound driver. No audio. 

Turned off enhancements as recommended by the troubleshooter - Still No audio. 

I have also tried restarting audio services as recommended here Fix sound problems in Windows 10

This may not be a driver specific issue as I face the problem with Realtek's driver and inbuilt Windows sound drivers. 

Thanks!

@amanevan, thank you for the response.

If a system restore point is not available on the PC, we will have to reinstall the OS.

Follow these steps to reinstall the Operating System on your PC:

1. Shutdown the computer. 

2. Turn the computer back on again and repeatedly tap on the ESC until a Startup menu appears. 

3. Press F11 once for System Recovery. 

4. Choose the Keyboard Layout. 

5. Click on Troubleshoot. 

6. Go to Recovery Manager and click on System Recovery. 

Note: Back-up all your data as System Recovery will delete everything that you had saved or installed on the computer. 

Hope this helps! Keep me posted.
