CS2 Mic Not Working – How to Fix in 2 Minutes

Table of Contents

📌 Quick Answer

If your mic isn’t being picked up in CS2, you simply need to make sure the correct input device is selected in Windows, the game, and Steam, then raise the mic threshold or volume. After that, test it and it should be working.

🎮 Step-by-Step: Fixing Mic in CS2

Follow these steps in order! by the time you reach the last one, you’ll likely be back in voice chat.

1. Check your hardware

Plug in your mic/headset securely; sometimes it’s just a loose jack.
Test the mic in another app (Discord/Skype) to ensure it works outside of CS2. If it fails there too, you might have a hardware fault.
If you have multiple input devices (webcam mic, headset mic, built-in laptop mic), unplug or disable the extras so CS2 won’t get confused.

2. Set your mic as the default input device in Windows

Right-click the speaker icon in the taskbar → Sound settings → under Input, select your mic.
Then click More sound settings → Recording tab → select your mic → Properties → Levels: set volume to 100%. If there’s a “Microphone Boost” tab, try +20 dB as a start.
Also check Privacy & security → Microphone: make sure apps (and Steam) have permission to use it.

3. In-game settings in CS2

Launch CS2 → Settings → Audio → Voice.
Ensure your mic is selected as the input device (not “Default” unless you know that’s correct).
Check the “Microphone Trigger Threshold” (if you’re using Push-to-Talk) — sometimes it’s set so high that your mic input never registers. Lower it or switch to “Open Microphone” if you prefer.
Adjust volume/gain so your teammates can hear you. Many mic problems in CS2 are simply because the game expects a louder input.

4. Check Steam’s voice settings

In Steam → Settings → Voice tab. Select your mic device there too. Set input volume/gain to max for testing.
Some users have found that if Steam is set to one mic and CS2 to another, the result is silence. Matching them helps.

5. Update drivers & reduce conflicts

Update your audio drivers (go to your sound card or headset manufacturer). Outdated drivers = mic woes in CS2.
Close other apps that might be using your mic (Discord, OBS, VR software) so CS2 has full access.
As a final resort: verify integrity of game files in Steam (right-click CS2 → Properties → Installed Files → “Verify integrity”). Sometimes audio components of the game get corrupted.

🕑 Two-Minute Summary

Plug mic in, test it outside CS2.
Set your mic as default in Windows and raise levels.
In CS2: select correct mic, lower threshold, raise gain.
In Steam: match mic device, raise input volume.
If still broken: update drivers, close conflicting apps, verify game files.

Once your mic is working again, hop back into CS2 and make the most of it; team calls make all the difference when opening cases on DaddySkins. Trade, chat, and win rare skins while communicating clearly with your squad.
