What do you do if the microphone of the Logitech g430 does not work?

I bought the Logitech g430 yesterday to talk to my friends (in the game Fortnite), but it does not work. I've already looked in the settings of the game, but there everything is set correctly…

Can anyone help me?

Have you ever tried it and looked if it is recognized by the PC. If so, see if the Mirkrofon is also recognized and see if the volume mirkos it was not set too low. When you talk ingame, look if you can choose or change the mic.

But on the headphones you certainly hear something or? If this does not help then look if you can exchange it and get your money back, if not too long ago
