What to Do if Your Microphone Doesn’t Work in CS2

What to Do if Your Microphone Doesn’t Work in CS2

Check CS2 Settings

Go to Settings → Keyboard & Mouse → Use Microphone — make sure a valid key is assigned (default is “K”).

Enable push-to-talk instead of voice activation.

Check your input device in Settings → Audio — select the correct microphone (headset or external card).

Test the Microphone Outside the Game

Open Windows “Sound Settings” and see if the input bar responds when you speak.

Make sure your mic isn't muted physically or on your sound card.

Console Command

Open the CS2 console and type:

voice_enable 1 

This re-enables voice chat in-game.

Additional Steps

Reconnect your mic or headset.

Try a different USB port or audio interface.

Reinstall CS2 to reset your CS2 config.

As a last resort, test the mic on another device or reinstall Windows.

If It Doesn’t Work in Steam

Steam no longer has its own microphone settings. Everything is handled via Windows, so the issue is either with your device or system.

Pro tip: Bind the mic to a convenient button (like a side mouse key) to communicate faster during rounds.
