Question PC cannot pick up XLR mic through audio interface ?

[harold.graham3000]

I have an AT 2020 XLR microphone connected to my Line 6 UX2 audio interface.

48V Phantom Power is on

I have Headphones connected to the 1/4 jack on the audio interface.

Neither my PC nor the Audio interface will pick up the mic.

I have installed the drivers for the audio interface.

This mic is brand new and I bought it from straight from Amazon (not a third party)

I do not know what to do from here. any help would be greatly appreciated. thanks

Rule-out the cable.
Check for an on off switch on the mic.
Check your gain on the interface.

Gain is at a reasonable amount
mic has no on/off switch
