How to Change Mic in CSGO & CS2 (Quick Fix Guide)

Why Your Mic Matters in Counter-Strike

In Counter-Strike, clear voice communication wins games. Whether you’re calling Mirage smokes, clutching a 1v2, or coordinating a rush, bad mic settings can ruin team play.

Many players struggle because Counter-Strike doesn’t always auto-detect the correct microphone — especially if you use:

• USB headsets
• External XLR mics
• Virtual audio devices

Let’s fix that properly.

How to Change Mic in CSGO (In-Game Method)

This is the fastest and safest way.

Step-by-Step:

1. Launch CSGO / CS2
2. Open Settings → Audio
3. Find Audio Input Device
4. Select your correct microphone
5. Click Apply Changes

Speak into your mic and watch the input bar move. If it reacts, you’re good.

If teammates still can’t hear you, continue below.

How to Change Mic Using Steam Settings (Recommended)

Steam overrides in-game audio — so this step is crucial.

Steps:

1. Open Steam
2. Go to Settings → Voice
3. Set your Input Device (microphone)
4. Disable automatic volume control
5. Test mic input

Restart CS after applying changes.

Fix Mic Not Working in CS2 (Common Causes)

If your mic still doesn’t work, it’s usually one of these:

1. Wrong Default Mic in Windows

• Open Sound Settings
• Set correct mic as Default Input

2. Push-to-Talk Key Not Working

Your counter strike mic key might be unbound.

Go to: Settings → Keyboard / Mouse → Communication

Default key: K

You can rebind it anytime.

The default push-to-talk key is K.

Should I use voice activation?
