Line input audio with Record not working in Windows 10 v1803 update

I was able to record sound through Windows Voice Recorder app in Windows 10 Pro on my Surface Pro 3, . However, after I upgrade the system to the April 2018 Update (version 1803), the speaker and recording function just stop working. I notice that Line In input device is missing. Both of the Audacity and Control Panel lack of the sound level. How can I resolve the problem on my tablet?

On my Windows 10 computer with version 1803 updatem, the “What U Hear” has been disabled in Sound Blaster. But it is no way to enable it again, so I could not recording any sound. I install the latest SB driver and nothing takes effect.
