After bios update, my audio is not working

[Saiakashdasari]

• I updated my bios and then audio symbol is showing red Cross on it.
• No sound or headphones are available. I tried everything. I tried to reinstall audio drivers. Restored my system but bios version didn't change.
• I tried to downgrade my bios. It is showing signature not verified. By using efi partition, I copied F.42 bios file in hp bios folder and tried to install. But still it shows signature not verified.
• What should I do??

Are you experiencing the same issue as described in this post? Have you tried all these steps? 

If the issue still persists, please back-up the data and try re-installing the operating system - 

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. 
 

Let me know.
