Windows 10: My microphone on my headset, controller or anything aren’t picking up my voice but I can...

Recently purchased the dgm20 from Amazon, plugged it into my pc, was working then BAM! Every device I use to hear wasn’t or stopped altogether working for my voice input, game chat doesn’t let me talk, discord doesn’t let me talk and I have tried everything!

Microphone does not pick up voice

My headset microphone is completely functional; however, my PC cannot pick up my voice. If I blow loudly in the microphone, the green bar on the sound control panel will light up but not when I talk normally. My drivers are fully updated and my microphone
levels are maxed out.

 

Headset, Microphone not picking up my voice however the earphones are?

When trying to use my headset to record screen editing the microphone was only picking up the lowest muffle of my voice, after trying everything and selecting my speakers to play anything going through the headset, I held the headset infrom
of my face and I could hear clearly but the earphones part is whats relaying my voice not the mic? how do i fix this I cannot just hold the earphones infromt of me

 

Microphone doesn't pick up voice.

I have a Windows 10 All-in-One. I've had this computer for about three months. For the first one and a half months, I've had no problems with this PC, but now whenever I plug in a headset, earbuds, or headphones the
computer doesn't pick up my voice. Whenever there is no headset plugged in my voice does pick up. This wasn't always a problem, I used to be able to Skype and use TeamSpeak, but now I can't do that. Cortana doesn't pick up my voice, and when I try to set up
a microphone it doesn't pick up my voice either. Is there any way to fix this in the settings? I've been looking online for days and it's really getting on my nerves because I can't find anything that works. I know somebody said they plugged in a speaker to
the computer and plugged their headset into that, but I do not own a speaker and I cannot buy one. If you know a fix please help me out.
