Does the logitech HD pro webcam c920 have a mic?

[Sky]

If it does, how do I enable it? I can't find the option to enable the mic. I looked through the device manager and when I go to properties it doesn't show anything about a mic or sound.

Yes it has a microphone, and it should be enabled by default. Did you already check the Windows sound settings, recording devices?
Else try updating the drivers from the logitech website.

I looked in the recording devices tab and it showed Anex virtual audio device. I don't know if thats the microphone in the webcam or its a diffrent microphone.

I didn't have any logitech drivers so I download them and the logitech webcam softwere aswell. I tried to do a video so I could play it back to see if it has sound. But after I prees rec it said that the logitech webcam softwere stopped respounding. When I tried to do a video call to my dad to test the sound to see if he could hear me, He couldn't hear me but O coild hear him and he could only hear this sound that didn't come from my room. So I don't know what cause that.

Also in FaceRig it says no sound detected even if I put the anex virtual aduio device (which is the only one mic it showed) in the recording options in facerig.

I got it to worked after looking on the micosoft support site for windows 10 someone had a prolbem where after they rec a video and played it back no sound came out. Someone respounded to it saying following these steps:

(a post from a support Engineer at micosoft)

Run Hardware and Device Troubleshooter.

Press Windows Key + R, type Control Panel.
Type Troubleshooting in the search bar, click on Troubleshooting.
Click on Hardware and Sound, click on Hardware and Devices.
Follow the steps from the wizard to run the Troubleshooter.

(edit update)
It worked but after I spoke on FaceRig (I had my computer speakers to play the audio after I spoken) It said what I said. After that it made this werid sound and made a eco and it kept on doing it making this annoying sound.

(last edit)
Ok I fixed the echo probllem by dissabling loopback in the options. And he can heara me.

But there is this one problem. After sometime the small box with the webcam of me dissapperd and the avater wont move when I move. I tried closing FaceRig and restarting it to see if that fixes it. But it didn't.

The echo is what you call "sound loopback" which is when the sounds goes to the microphone, out the speakers and THAT sound goes in the microphone, and out the speakers, and again, and again.... making a very loud, annoying sound. If you use sound-loopback ONLY use this with headphones, as that sound will not be picked up by the microphone, not making the sound-loopback.

For the webcam problem: is the box with you in it just gone or is it a black / grey box?
If just gone: you probably toggled pic-in-pic off, to turn it back on, switch to advanced UI (right-most button) and then turn on pic-in-pic (one of the other buttons on the top, don't know by heart which one)
If you then see yourself but it still doesn't move, check the button close to the picín'pic button called "facetracking" and make sure it is ON.
If it (then) is a grey / black box, while in the advanced UI, go to settings (the gear icon on the site), devices, and re-select your webcam from the list.

I fixed the black screen problem by doing a systam restore. I just forgot to post it because it was late.

So everythings fixed. But I still don't know how that black screen happend.

Glad the issue was fixed, for the black screen, it can also be that another program was using your webcam feed, besides the ones enumerated by FurRiffic.
