[SOLVED] Can't use microphone on Windows 10!

[khangnt2005]

My Windows build is 1909.
I tested with 2 headphones with a mic but none of them could be used to talk in games, to be more specific, CS:GO. My first headphone is a cheap chinese one, it worked perfectly before but now, I can't use mic in game. When I enable mic in windows, the microphone icon shows up in the taskbar but I can't hear anything in the game but the game does recognize that I'm using the mic when I press the button to talk, wonder if my teammates could hear me because I can't hear anything. When I turn off the mic in windows, I am able to hear sounds again but the game doesn't recognize that I'm using the mic and won't show any sign of me talking when I press the push to talk button. The second headphone is the Razer Hammerhead BT, seems like the same thing happens to this headphone too, does anyone got any solutions?
Thanks

You need to tell Windows which sound device is used for audio output to speakers or headphones and which is for sound input for your microphone. Right click the sound volume icon next to the clock on the Windows taskbar and select Open Sound settings. You can then pick which sound device is used for whichever output or input you want.
