Troubleshooting: How to Fix a Mic Not Working on Your Chromebook

Chromebooks have become increasingly popular for their simplicity, speed, and affordability. Whether you’re a student attending online classes, a professional in virtual meetings, or simply enjoying some online gaming, a functioning microphone is essential. However, like any piece of technology, Chromebooks can sometimes encounter microphone issues. If you’re finding your mic isn’t working, don’t panic! This comprehensive guide will walk you through numerous troubleshooting steps to get your microphone back in action.

Understanding Common Microphone Issues on Chromebooks

Before we dive into specific solutions, let’s understand some common reasons why your Chromebook’s microphone might not be working:

• Incorrect Input Selection: Your Chromebook might be set to use the wrong microphone input (e.g., an external mic when you want to use the built-in one).
• Muted Microphone: The microphone might be accidentally muted in your system settings or within the specific app you are using.
• Outdated Software: Outdated ChromeOS can sometimes cause conflicts with hardware, including your microphone.
• App Permissions: The app you’re trying to use might not have permission to access your microphone.
• Hardware Issues: While less common, there could be a physical issue with the microphone itself.
• Conflicting Extensions: Certain Chrome extensions might be interfering with microphone functionality.
• Browser Issues: Sometimes, cached data and corrupted browser settings can lead to microphone problems.

Step-by-Step Troubleshooting Guide

Now, let’s explore the solutions. We will start with the easiest fixes and then move towards more advanced troubleshooting steps. Perform each step and check if your microphone is working before proceeding to the next one.

1. Basic Checks

These are quick checks you should always do first:

• Physically Check the Microphone: If you are using an external microphone, ensure it is properly plugged into the correct port on your Chromebook. Try using a different port or a different cable to rule out connection issues. If you’re using a headset with a microphone, check that the headset’s microphone arm or in-line microphone isn’t muted or physically obstructed.
• Check the Mute Button: Many Chromebooks have a dedicated mute button on the keyboard. Make sure it is not active. The mute button is often indicated by a microphone icon with a line through it. Tap it once to unmute the microphone if it is enabled. Some keyboard manufacturers also implement function key combinations (e.g. Fn + F8, or Alt + M) that can mute the microphone, check your keyboard’s manual for your specific combination.
• Restart Your Chromebook: A simple restart can often resolve temporary glitches. Close all open apps and click on the time in the bottom right corner of your screen. Select the power icon, and then select restart. After the Chromebook restarts, test your microphone.

2. Verify Microphone Input Settings

Your Chromebook has settings to choose which microphone to use. It may be that an incorrect microphone is selected as default. Here is how to check and modify the settings:

1. Open Settings: Click on the time in the bottom-right corner of your screen, then click the Settings icon (the gear icon).
2. Navigate to Sound Settings: In the Settings menu, click on “Device” in the left-hand menu, then select “Audio” in the sub menu. Alternatively, you can use the search bar at the top of the settings menu and search for “Audio”.
3. Select the Correct Microphone: In the Input section, click on the dropdown menu under “Input Device”. Make sure that your desired microphone (e.g., Internal Microphone or the name of your external microphone) is selected.
4. Adjust Input Volume: You can also adjust the input volume slider to control microphone sensitivity. Try increasing the volume to see if it improves the microphone input.
5. Test Your Microphone: ChromeOS typically includes an “Input Device” tester at this menu, it displays a visual graph of the input, speak into your microphone and verify if the graph registers any sound.

3. Check App Permissions

Apps need explicit permission to access your microphone. Here’s how to check and modify these permissions:

1. Open Settings: Again, click the time and then click Settings (the gear icon).
2. Navigate to Privacy and Security: In the Settings menu, click on “Privacy and Security” in the left-hand menu.
3. Go to Site Settings: Click on “Site Settings”.
4. Select Microphone: Scroll down or use the search bar at the top of the settings menu and search for “Microphone” then, click on “Microphone”.
5. Manage App Access: Here, you’ll see a list of websites and apps that have asked for microphone access. You can select an app and either allow or deny microphone access for each one. If the app you are having problems with is in the block list or marked as “Ask”, ensure you change the setting to “Allow”. In the case of asking you can still allow the microphone but every time the app will ask permission for the microphone.

4. Update ChromeOS

Outdated software can cause microphone glitches. Make sure your Chromebook is running the latest version of ChromeOS:

1. Open Settings: Open your Chromebook’s Settings menu.
2. Go to About ChromeOS: Click on “About ChromeOS” in the left-hand menu.
3. Check for Updates: Click on “Check for Updates”. If an update is available, install it and then restart your device.

5. Disable Conflicting Extensions

Some Chrome extensions can interfere with microphone functionality, especially if they modify audio or microphone usage. To troubleshoot, try disabling extensions:

1. Open Extensions: In your Chrome browser address bar, type chrome://extensions and press Enter.
2. Disable Extensions: Disable the extensions one by one, and check after each disabled extension to see if the microphone is working. Start with extensions that relate to audio or that have broad permission access. You can re-enable extensions once you’ve identified the one causing the issue (or none at all).

6. Clear Browser Cache and Cookies

Sometimes, cached data and cookies can cause website and microphone issues. Try clearing your browser’s cache:

1. Open Chrome Settings: In your Chrome browser, click the three dots in the top-right corner, then click on “Settings”.
2. Go to Privacy and Security: Click on “Privacy and security” in the left-hand menu.
3. Clear Browsing Data: Click on “Clear browsing data”.
4. Choose Time Range: Choose a time range (e.g. “All time”).
5. Select Items to Clear: Make sure “Cached images and files” and “Cookies and other site data” are selected. You can also select other items if you wish.
6. Clear Data: Click “Clear data”.

7. Use the ChromeOS Diagnostic Tool

ChromeOS comes with a built-in diagnostic tool that can help detect hardware issues. To use it:

1. Open Diagnostics: Go to chrome://diagnostics in your browser address bar.
2. Run the Microphone Test: Locate the “Audio” section and start the microphone test by clicking the corresponding “Run” button. Follow the prompts to complete the diagnostic.
3. Review the Results: The tool will provide feedback on the performance of your microphone, including any detected issues.

8. Test with Different Applications

The issue might be specific to one application. Try testing your microphone with different applications that use it, such as: Google Meet, Zoom, a web-based audio recorder, or even the ChromeOS recorder tool. If the microphone is working correctly with other applications, the issue might be with the settings or permissions of the specific app that isn’t working. In this case, ensure you follow steps 3 and verify permissions for that app. If the app is web based, make sure you clear the cache and cookies, as described in step 6.

9. Test External Microphone on Another Device

If you are using an external microphone, try connecting it to a different device (e.g., another Chromebook, laptop, or phone). This will help you determine if the microphone itself is faulty, or if the issue is with your Chromebook.

10. Perform a Powerwash (Factory Reset)

As a last resort, you can try a Powerwash. A Powerwash will reset your Chromebook to its factory default settings and erase all local data, make sure you backup your data to the cloud before attempting this. Here is how to perform a Powerwash:

1. Open Settings: Open your Chromebook’s Settings menu.
2. Go to Advanced Settings: Click on “Advanced” in the left-hand menu.
3. Go to Reset Settings: Click on “Reset Settings”
4. Click Powerwash: Click on “Powerwash” and follow the prompts to complete the reset.
5. Test the Microphone: After setting up your Chromebook again check if the microphone works.

When to Seek Professional Help

If you have tried all of the above steps and your microphone still isn’t working, it’s likely a hardware issue. In this case, it’s best to contact the manufacturer of your Chromebook or seek help from a certified technician or tech support team. Do not open the device on your own, as this can void the warranty. Provide them with all the steps you’ve already taken for a quicker and more efficient support service.

Conclusion

A malfunctioning microphone on your Chromebook can be frustrating, but with a methodical approach to troubleshooting, you can often resolve the issue yourself. By systematically working through these steps, you’ll be well on your way to getting your microphone working again. Remember, start with the basic checks and move on to more advanced solutions if needed. Happy conferencing, gaming, or recording!
