I have a E6230 running Windows 10.

For me when I go to Settings ---> Sound . And scroll down to Input, I see Microphone (High Definition Audio Device). Below that I see Test your microphone .  

.

I saw in another post that there is a setting to enable/disable microphone in BIOS.

So, reboot, tap F2 repeatedly to get into BIOS.

Go to System Configuration ---> Miscellaneous Devices

@auntiebk 

What version is your BIOS?

It is always risky to update the BIOS, but I know I did update the BIOS on my E6230. Sometimes you do need the newest BIOS for Windows 10.

The other option is to buy an external microphone.

.

Thanks so much for trying to help.  Alas, the Bios doesn't list a separate Microphone.  Saw this posting, but neither does my pc have the "High Definition Audio Device (Not  IDT High Def...  this is important.) " driver referred to.   https://answers.microsoft.com/en-us/insider/forum/insider_wintp-insider_devices/idt-high-definition-audio-codec-not-working-on/570a5038-e48e-43f3-af75-95da61447c87?tab=AllReplies#tabs

I'm a little afraid to uninstall the drivers and reinstall as the Microsoft guy recommends... :

BOIS version A22,

Audio controller: IDT 92HD93

Don't see where microphone appears in BIOS/setup?

Tried plugging in my earbuds to the jack on the left edge, could hear but speaking brought forth no sound.

Really appreciate your efforts!

@auntiebk 

Are you saying you don't see System Configuration   ---   Miscellaneous Devices in the BIOS  ? ? ?

Sorry my bad confused BIOS with Settings/System/Sound/Input devices. 

In Bios, System Configuration, Miscellaneous Devices YES there is a listing for microphone and it is enabled, as are the other misc devices (internal modem, module bay, media card etc.)  

In Settings/System/Sound/Input devices, only Rec. Playback (IDT High Definition Audio CODEC) appears.  There is no separate drop down entry for a microphone.

Is the Rec. Playback IDT etc the sound card?  Could it be bad since when I plugged earbuds into the jack the ear buds' microphone didn't pick up my sound either?

Rreally really appreciate your help.

In Device Manager, I have a section Audio inputs and outputs with two entries:

Microphone (High Definition Audio Device)

Speakers (High Definition Audio Device)

both are using Microsoft drivers not IDT drivers.

I am suggesting that you uninstall the IDT drivers following the procedure described here

--> https://www.digitalcitizen.life/completely-remove-faulty-drivers-windows

And let Windows 10 find the needed drivers.

@auntiebk 

I am also running the latest version of Windows 10 Pro  v1909

The E6230 that I have and the E6430 that you have both have the same audio controller IDT92HD93 , so you should be able to get the internal microphone to work.

.

10.0.17763.1098 , with delayed windows updates like most businesses use.   I removed the IDT driver as suggested, next time I looked at Device manager, the IDT device was gone and in its place the generic "High Definition Audio Device" appeared.

Now "No input devices found" in Settings/Sound/ Input.

It seems the microphone array? is part of the onboard webcam?  Is there a separate driver for that?

Device manager also lists 4 NVIDIA High Definition Audio devices, one each in locations 0, 1, 2 and 3.  Could there be some kind of conflict between audio devices?

Thoroughly confused, frustrated and exhausted.

@auntiebk 

nVidia is for graphics  ; maybe you have that ; it is odd that it shows up as an audio device

I only have the Intel HD Graphics 4000 .

You are running Windows 10  v1809 which is 2 builds older than the one I am running.  That's what I get when I search on 17763.1098  .  

I am running Windows 10 v1909  which is OS build 18363.720

Thanks @nyc10026.

My pc guy advises this model laptop has no internal mic.  Was security feature designed for biz execs.  There was a docking station option that included a mic.

Go figure.

Thanks again!
