Try the following.

Download the IDT Audio installer  and save it to your Downloads folder.

Though you have same driver installed previously, stay calm and follow the given steps. When done,

1. Open windows Control Panel, 
2. Open Device Manager and 
3. Open up Sound, Video and Game Controllers.  
4. Right click the IDT device and select Uninstall - you should also get a prompt to remove the current driver, tick the box to allow this and then proceed with the uninstall.
5. When complete, restart the notebook.

Let Windows fully load - it will automatically load an audio driver, but just let this complete.
Then

1. Open your Downloads folder, 
2. Right click on the IDT installer and select 'Run as Administrator' to start the installation.  
3. When this has completed, check if you have the Enhancements tab back.

Note:  If you want the fn+B combination to work correctly, you'll need to download and install HP Quick Launch.

When the installation has completed, restart the notebook before checking.
