That is basically what I see. There’s no enhancements, it was there in Windows 8.1. It was gone when I updated to Windows 10.

I tried uninstalling and reinstalling the Conexant SmartAudio HD driver, tried downloading the driver from Toshiba’s website that matched my laptop’s model, tried updating the driver, nothing works. 

Is there a way to bring back the enhancements tab?

I have check on a Windows 10 computer and was able to see and work with the sound enhancements.

If you are not able to see the same then it could be because the sound card installed on the computer do not have the ability for displaying sound enhancements or the sound card drivers are corrupt.

Step 1:

You may try uninstalling and re-installing the sound card drivers from device manager and

a. Type in Device Manager in the Start Screen. Select the same.

b. Expand Sound, Video and Game Controllers in the Device Manager Window.

c.Right click on the Device.

d.Click on Properties.

e.Click on Driver Tab.

f.Click on Uninstall drivers.

g.Click OK.

Now restart the computer and install the latest drivers and check if the issue still persists.

Step 2:

If the issue still persists, reinstall the latest drivers from the manufacturer’s website and check.
