To turn on your microphone in CS2, first select it as the input device in your Windows sound settings, then in the game open Settings, go to the Audio tab, and check the voice activation mode; in the Keyboard and Mouse section you assign the push-to-talk key. To check how your teammates hear you, use the console command voice_loopback 1. Below, step by step: connecting the mic, configuring it in the operating system and in the game, useful commands, and what to do if the microphone doesn't work.
In a team game, voice comms directly affect the outcome of a round: callouts about enemy positions and buys reach your team much faster than through text chat.
Why use a microphone
Talking is far quicker than typing. You don't have to take your hands off the controls to write a message, so you can keep communicating in the middle of a round.
Voice lets you pass on key information about where opponents are, what weapons they carry, and what they bought. It also helps outside the tactical side: casual conversation with teammates keeps long sessions less tiring, and it is a good way to meet new people to play with.
How to connect the microphone to your device
Start with the operating system, because CS2 itself does not let you choose the input device or adjust its parameters. The first step is physically connecting the microphone. There are two main types:
Studio: excellent sound quality, but it needs a separate audio interface. It allows fine-tuning and is fairly expensive.
Standard: cheaper than a studio mic, with lower sound quality. Unless you stream CS2 or need broadcast quality, this is the sensible choice.
Connecting a wired microphone
To use your microphone in CS2, first connect it to the sound card of your desktop or laptop. Laptops usually have a combined jack that takes both headphones and a microphone.
Desktop PCs sometimes have a combined jack too, but more often there are separate ones: one for the microphone and one for the output device. The microphone jack is labeled and colored pink or red. Plug the mic in, then install the drivers from the manufacturer's official website if your model needs them.
Connecting a wireless microphone
You can also connect a microphone over Bluetooth. First make sure both your computer and the mic support it; the microphone usually has a pairing button or switch, so check its manual. Not every PC or laptop has a built-in Bluetooth module, and in that case an inexpensive USB adapter does the job:
Open Settings on your computer.
Go to Devices (Bluetooth & devices in Windows 11).
Turn on Bluetooth and add your microphone. Its name is printed on the box or in the manual.
How to configure the microphone in the OS
Once the microphone is connected, configure it in the operating system and then in the game. To check that it works and adjust it, do the following:
Open Settings, then System.
In the Sound section, find Input and pick your microphone. Select it by name, because Windows sometimes defaults to the sound card or another input device.
If the input level bar moves when you speak, the microphone is working. The higher the level, the louder you sound.
Open Device properties.
Here you can change the microphone volume and other settings.
If you are sure the right input device is selected but it still doesn't work, run the Windows troubleshooter and follow its instructions.
The exact location of buttons and settings depends on your operating system version. If you can't find a section, search for a guide for your specific version.
How to configure the microphone in Counter-Strike 2
When the microphone works in the system, move on to the game. Launch CS2, open Settings, and go to the Audio tab. Voice chat in a party works the same way; for more on playing together, see the guide on how to play CS2 with friends.
Check that voice is set to activate with a key; otherwise the microphone stays open all the time and your teammates hear background noise. The voice chat volume slider controls how loud your teammates are, so set it relative to your headphone volume.
The positional voice option makes teammates louder or quieter depending on where they are on the map. It sounds useful, but in practice it tends to get in the way and makes callouts harder to follow.
In the Keyboard and Mouse section you can set the push-to-talk key (or create a bind through the console). If you can, use a side mouse button or a convenient key you don't already use. Reaching across the keyboard in the middle of a firefight just to talk is not comfortable.
Console commands for the microphone
Setup doesn't stop at the sound card and the in-game menu; a few console commands help too. Make sure the developer console is enabled and you can open it (see how to open the console in CS2). The commands below relate to voice chat; the full list is in our collection of CS2 console commands.
voice_loopback 1: lets you hear your own voice the way teammates hear it. Handy for checking that the mic works and for tuning its level.
voice_scale [number]: accepts values from 0.001 to 0.99 and sets the voice chat volume of all other players on the server.
snd_restart: restarts the sound system. Useful if you join a server with distracting music playing.
voice_fadeouttime [number]: accepts values from 0.001 to 0.999 and controls how your voice fades out at the end of a transmission.
What to do if the microphone doesn't work
If the microphone works in Windows but not in CS2, first check the Windows privacy settings to make sure apps are allowed to access the microphone, then verify the game files in Steam (game Properties, Installed Files, Verify integrity of game files). Reinstalling the game is a last resort. If the microphone doesn't work at the system level at all, the problem is more serious.
First, check the connection. The cable must go either into the separate pink jack labeled "mic" or into a combined jack. Inspect the microphone and its cable for damage.
Run the troubleshooter in the microphone settings. If that doesn't help, take the microphone back to the store under warranty or to a repair technician.
Keep in mind that studio microphones can't work without extra equipment. Some only need an audio interface, while an XLR microphone, for example, needs a preamp and a converter, without which no sound reaches the PC.
If you don't want to spend on extra gear, ask the seller what type of microphone you are buying before you pay.
FAQ
Why can't my teammates hear me in CS2?
Usually the wrong input device is selected in Windows, apps are blocked from accessing the microphone, or no push-to-talk key is assigned in the game. Check each in turn and use voice_loopback 1 to hear yourself.
Can the microphone work without pressing a key?
Yes. In the Audio tab, switch from push-to-talk to an open microphone. Your team will then hear background noise, so push-to-talk is usually the better option for matches.
Does the same setup work on FACEIT?
FACEIT voice chat is configured separately; the steps are in our guide on how to enable voice chat on FACEIT.
