Mic not working/ too quiet

[Fyre]

I just received a usb audio adapter in the mail, and I plugged it in and set it up with my HyperX cloud alphas. The adapter i got is the Plugable USB audio adapter. So I got the thing set up and I can hear the audio nice and good, but then when I try my mic, it is acting up. When I view the test my microphone setting in windows (10), even when I make really loud noises, the bar doesn't move, and it only picks up any audio coming from the mic when I plug and unplug the jack. I went into properties and tried to raise the gain on it, but there is no gain bar for some reason. Does anyone know how to fix this?

Thanks in advance.-

It also seems that it will only pick up on noise when I inhale into the mic.

No gain slider is a very odd problem. You can try this: https://antlionaudio.com/blogs/news/what-to-do-if-your-modmic-is-too-quiet

 

Also try a different USB port, may be an issue with your USB port and that particular adapter.
