Windows 10: Lost built-in audio. How do I get it back?

I am running Windows 10 build 10586.

I was trying to get WebEx to work with an external webcam and an external microphone this afternoon and, in the process of trying to get the audio working, I disabled (*just* disabled) the built-in Realtek audio. That didn't solve my original problem and it caused a new one: now, when I disconnect the external microphone, I have no devices in my Sound/Recording tab at all. Normally, the Realtek audio shows up.

I went to Device Manager to make it do a detect of new devices, which sometimes solved problems like this in previous versions of Windows but Win10 doesn't have that option any more! I thought a reboot would make Windows see the Realtek audio again but that didn't work either.

What do I do to recover my built-in microphone so that I can use it again?

For what it's worth, the internal webcam still works and can broadcast video; it's only the built-in *audio* that won't work.

I'm using a 4 month old Dell 5559 laptop if that makes any difference.

I lost Internet Explorer. How do I get it back?

In the past month, the apps I can't open has continued to increase. Now I can't find IE anywhere in the stuff I can access. This is Windows 10.

Thanks!

 

Are your speaker's working ?

 

Yes, the speakers are working fine.

For what it's worth, I think I've resolved the basic problem. I went to dell.com and chose the support option and my model of laptop, then downloaded new audio drivers. That involved removing the old drivers, rebooting, installing new drivers and rebooting again but when I tried making a short recording with the Camera option, the audio and video were both working on playback.

I still can't get WebEx to work with the internal microphone but I've opened a support case with them. Maybe they'll be able to figure out the problem since audio in Windows now appears to be working.
