How to Change the Microphone in CS2
Source-checked About 5 minutes
Answer
Open Steam's Friends & Chat window, select the Settings gear > Voice, and choose the microphone under Voice Input Device. Run Start Microphone Test there, then launch CS2 and hold your configured push-to-talk key in a private test. Selecting Default makes Steam follow the Windows default input instead of a fixed microphone.
If it does not work
- If the microphone is missing from Steam, confirm Windows detects it and allows desktop apps to use the microphone, then reopen Steam after reconnecting the device.
- If Steam's microphone test works but CS2 does not, check the in-game voice-chat setting and push-to-talk binding. Do not change the selected input again until the key binding is confirmed.
- If Steam keeps returning to another microphone, select the device by name instead of Default, or change the Windows default input if you intentionally want Steam to follow it.
