How to Fix a Microphone Not Working in a Steam Game
Source-checked About 10 minutes
Answer
Confirm the microphone works in the operating system, grant the game microphone access, select the correct device in Steam and the game, then disable exclusive or virtual audio conflicts one at a time.
Test the microphone outside Steam
Use the operating-system sound input test and confirm the intended microphone meter moves before changing the game.
Grant microphone privacy access
Allow desktop apps, Steam, and the game to use the microphone in Windows or macOS privacy settings.
Choose the Steam input
Open Steam Settings > Voice, select the intended input device, set a reasonable gain, and run the microphone test.
Choose the in-game input
Open the game audio or voice settings, select the same device, and check push-to-talk key, open-mic threshold, team channel, and mute state.
Check the physical audio route
Reconnect the headset, verify hardware mute, and disconnect unused Bluetooth or virtual audio devices for the test.
Restart after device changes
Close the game and Steam completely, set the intended microphone as system default, reopen Steam, then launch the game.
Isolate game-specific failure
If Steam’s test works but one game fails, report the game, input device, privacy state, voice mode, and another-game comparison to that game publisher.

If it does not work
- If the Steam microphone test has no input, verify operating-system privacy access, hardware mute, and the system default device before opening a game.
- If Steam’s test works but one game is silent, keep the working Steam device and inspect that game’s input selection, push-to-talk key, threshold, channel, and mute state.
