Microphone Settings Guide

1. Right-click the speaker icon in the taskbar → Sound settings.
2. Under Input, choose your microphone and speak: the volume bar should move.
3. Open the device → set Input volume to 70–90 %.
4. Go to Privacy & security → Microphone and allow access for apps and desktop apps.
5. If the mic is missing, open More sound settings → Recording, right-click → Show disabled devices and enable it.

Windows 10 can block the mic system-wide. In Settings → Privacy → Microphone, turn on “Allow apps to access your microphone” and, further down, “Allow desktop apps”. Browsers need both.

Browser microphone permissions

Click the padlock or tune icon in the address bar → Site settings → Microphone → Allow. On Android, also check Settings → Apps → Chrome → Permissions → Microphone; on iPhone, Settings → Safari (or Chrome) → Microphone. Then reload and test on the mic test.

Check whether your microphone is working

Open the mic test and speak. If the meter moves, the microphone and drivers are fine; any remaining problem is in a specific app's settings. If it does not move, continue with the fixes below.

1. Press Win + X → Control Panel → Hardware and Sound → Sound.
2. Open the Recording tab and select your mic → Set Default.
3. Properties → Levels: set the level and boost.
4. In PC settings → Privacy → Microphone, allow apps.

1. Start → Control Panel → Sound.
2. Recording tab → right-click empty space → show disabled and disconnected devices.
3. Select the mic → Set Default → Properties → Levels.
4. Use Configure to run the speech setup wizard if needed.

1. Start → Control Panel → Hardware and Sound → Sound.
2. Recording tab → choose the mic → Set Default.
3. Properties → Levels to adjust volume; Advanced for sample rate.

1. Start → Control Panel → Sounds and Audio Devices.
2. Audio tab → Sound recording: choose the default device.
3. Volume → Options → Properties → Recording → tick Microphone and raise its slider.
4. Voice tab → Test hardware runs the wizard.

1. Apple menu → System Settings → Sound → Input.
2. Select the microphone and watch the input level while speaking.
3. Set the input volume slider around 75 %.
4. Under Privacy & Security → Microphone, enable your browser.
5. On older macOS, the same options are in System Preferences → Sound → Input.

1. Open Settings → Sound.
2. Under Input, select the device and check the level meter.
3. For advanced control install pavucontrol and use its Input Devices tab.
4. If the mic is muted, run alsamixer, press F4 and unmute capture with Space.

Speak normally: peaks should reach about −12 to −6 dBFS. Too low leaves hiss after boosting, too high clips. Avoid “Microphone boost” unless the mic is very quiet.

• Mic Test
• Voice Recorder

Mic level bars move but apps do not hear you

The app is set to another input or blocked by privacy settings.

No bars at all

Wrong device selected, muted, disabled, or a driver problem.

Mic missing from the list

Show disabled devices, reconnect, try another port, reinstall the driver.

Disable exclusive control

Device Properties → Advanced → untick exclusive mode.

Connect Bluetooth headsets manually

Pair again and choose the Hands-Free device as input.

Install the right audio driver

Use the laptop maker’s driver rather than the generic one.

Remove leftover VoIP apps

Old call software can hold the mic; uninstall unused ones.

Mac: reset NVRAM, new user, dictation, safe mode

Resetting NVRAM, testing in a new account or safe boot isolates software problems; enabling Dictation can reinitialise input.

Linux: microphone missing from volume menu

Use pavucontrol to unhide and select the source.

Run the audio troubleshooter

Windows Settings → System → Troubleshoot → Recording audio.

Scenario-based fixes

Check whether the Mac microphone works

Open Sound → Input and watch the level bars while speaking.

Reset PRAM/NVRAM on Intel Macs

Restart holding Option+Command+P+R for 20 seconds to reset audio settings.

Create a new user account

If the mic works in a new account, settings in your profile are corrupted.

Mic configured and bars move but apps still fail

Check per-app permissions and the input selected inside each app.

Windows mic configured but not detected

Set it as the default communication device as well as the default device.

Bars move but the computer does not detect your voice

App-level input or exclusive mode problem; set default device and disable exclusive mode.

No bars appear on any device

Hardware, cable or driver issue; test the mic on another computer.

Hardware compatibility

Some 4-pole headset plugs need a splitter on PCs with separate mic and headphone jacks.

Remove the mic from Devices and Printers

Uninstall it there, unplug, restart and reconnect to reinstall cleanly.

Run Windows Update

Updates often include fixed audio drivers.

Check Windows 7, 8.1 and Vista configuration

Use the Recording tab, set default, check levels and run the troubleshooter.

Final tips

Try another USB port, avoid unpowered hubs and keep drivers current.

• Check the hardware mute and inline switches.
• Raise the input level and confirm the correct device is the default.
• Disable exclusive mode (Sound Control Panel → Recording → Properties → Advanced).
• Close VoIP and recording apps; uninstall any that install virtual audio drivers you no longer use.

1. Show disabled and disconnected devices in the Recording tab and enable it.
2. In Device Manager, scan for hardware changes; uninstall the device and restart.
3. Install the driver from the laptop or interface maker's site.
4. Try another USB port or cable, and check the BIOS for disabled onboard audio.

Allow microphone access for desktop apps, select the device inside the app, and turn off the app's automatic input sensitivity while testing.

If one app cannot use the mic on macOS, check Privacy & Security → Microphone for that app. Turning on Dictation in Keyboard settings is a quick way to confirm the system can hear you.
