4. Change the Steam Voice Input Device

The microphone problem in CS2 might also be related to your Steam Voice Input Device settings. You need to make sure that the correct microphone is set as the Steam Voice Input Device.

Doing so ensures that your mic is the default input device for all Steam games, which can help maintain consistent voice input settings.

  1. Open Steam and click on the “Friends and Chat” option at the bottom-right corner.
