How do I troubleshoot my microphone?

Check Your Microphone Settings

The first step in troubleshooting microphone issues is to check your microphone settings in your operating system. Make sure the microphone is set as the default recording device and the volume is turned up.

To check your microphone settings on Windows 10 or 11:

  • Open the Start menu and select Settings > System > Sound.
  • Under Input, find the microphone you want to use and select it.
  • Confirm the microphone is not muted and the volume level is turned up high enough (cite:
  • Select Device Properties and on the Levels tab, check the microphone volume is set to 100 and boost is on.
  • Select the Advanced tab and confirm the microphone is set as Default Device and Default Communication Device.

Checking these core microphone settings will resolve issues caused by incorrect configurations. Make sure the intended microphone is selected and not muted before troubleshooting other potential causes.

Update Your Drivers

Keeping your audio drivers up to date is one of the most important troubleshooting steps when dealing with microphone issues. According to an article on, “audio driver updates are essential for enhancing sound quality and performance on your computer. By regularly updating your audio drivers, you can fix bugs, improve compatibility with new hardware/software, and unlock features that optimize recording and playback” (source). Outdated drivers are a common reason microphones stop working properly.

To update your audio drivers, first identify your microphone or sound card manufacturer. You can find this in your Device Manager. Then, visit the manufacturer’s website and look for the latest audio driver available for download. For built-in audio like Realtek HD Audio, search for “update Realtek audio drivers” to find the latest versions. Install the new driver and then restart your computer. With updated drivers, your microphone has the best chance of working properly.

Test Your Microphone

One of the quickest ways to troubleshoot a microphone issue is to test it using a built-in utility or online tool. This isolates the microphone and helps determine if the issues lie with the hardware itself or related software and settings.

Open the Voice Recorder app on Windows or QuickTime Player app on Mac, and test recording your voice. Speak at normal levels, as well as very softly and very loudly. Playback the recording to check for issues like static, distortion, gaps in audio, etc. Refer to Mic Test to analyze things like frequency response.

You can also test your microphone during an online video call using apps like Zoom or Skype. Ask the other caller if they hear any problems with your audio feed. This tests the microphone’s functionality in real-world uses.

If the recordings sound clear in these isolated tests, then the problem likely lies with a particular app, software, or settings. If the issues persist, then your microphone hardware may need troubleshooting.

Try a Different Microphone

If you are having issues with your current microphone, one of the easiest troubleshooting steps is to connect a different external microphone or headset to your computer, phone, or recording device. This allows you to isolate whether the problem lies with the original microphone hardware itself or something else in your setup.

Test the new microphone in the same location and settings as the original one to determine if you can pick up clear audio input. Make sure to try different connection ports if possible. If the new microphone works fine, then the problem likely lies with your original microphone, either due to hardware defects, damaged cables, compatibility issues, or other flaws.

However, if you still cannot get decent audio input with multiple microphones, the issue may be related to misconfigured software settings, outdated drivers, electrical interference, or a problem with the device you are connecting to. But starting with a different physical microphone is helpful to narrow down where the root cause resides before digging deeper.

If a new microphone resolves your issues, you may need to repair or replace your original microphone. But first, check for solutions like updating drivers, adjusting software settings, using a different port, replacing cables, or cleaning microphone hardware. With some troubleshooting steps, you may be able to restore the original microphone without needing to purchase a replacement.

Check Your Cables and Connections

One of the most common issues with microphones is a problem with the cables and connections. Inspect all cables and connections thoroughly to ensure there is no damage or loose connections.

Examine the entire length of XLR and USB cables for any cuts, tears or exposed wiring. Damaged cables can cause issues with signal transmission resulting in noise, intermittent sound or no audio at all. Replace any visibly damaged cables immediately.

Check that all connections are fully plugged in and firmly secured. Loose connections between the mic and cable or cable and interface can also cause signal issues. Unplug and reconnect all connections, making sure to fully insert the plugs until you hear a click. Tighten down any locking rings or screws on XLR connections.

Pay particular attention to the connection at the base of the microphone itself. If using an XLR mic, check that the connector is properly seated in the mic output. Gently wiggle the connector to confirm it is locked in place. If using a USB mic, make sure the USB plug is fully inserted into the mic.[1]

If your cables and connections check out, the issue may be with the mic, interface or computer settings instead. However, faulty cables are a common oversight that can easily be fixed.


Adjust Your Microphone Settings

One of the easiest troubleshooting steps is to try tweaking your microphone settings to find the optimal audio quality. The sound properties in Windows and Mac provide advanced options to customize things like volume, boost, noise suppression, and more. According to this Reddit guide, you’ll generally want to set your microphone volume around 60-70% to avoid distortion. Enable noise suppression to cut out ambient background noise. Try boosting certain frequencies if your microphone sounds tinny. Play around with leveling options to prevent the volume from peaking. Running a mic test after each adjustment will help dial in the right settings.

Tools like WO Mic and Adobe Audition also let you fine-tune audio filters to improve microphone quality. The key is finding the right balance between boosting the signal while minimizing noise. Be careful not to overprocess the sound with too many effects. With some tweaking of your system’s microphone properties, you can often improve the audio substantially without buying expensive gear.

Inspect Your Hardware

One common cause of microphone issues is physical damage or obstructions to the hardware itself. Carefully inspect your microphone and headset for any signs of damage like bent connectors, frayed wires, cracks, debris blocking the mic hole, etc. Check where the microphone plugs into your computer or device – make sure the jack is clean and undamaged. Look over the entire length of the cable for damage as well.

As microphones contain delicate components, even a small amount of damage can prevent them from working properly. Refer to your device’s manual for steps to safely clean your microphone jack and hardware. Avoid blowing compressed air directly into the mic to prevent damaging sensitive internal components. If you find any significant damage, the safest bet is to replace the microphone.

Additionally, inspect the area around your microphone for any obstructions. Objects too close to the mic can physically block sound waves or cause interference. Remove any obstructions and make sure you have at least 6 inches of clearance around the microphone during use. Proper positioning is key for optimal audio quality.

If the hardware appears undamaged and there are no obstructions, the issue may lie in the microphone settings or drivers instead. But inspecting the physical condition is an important first step in troubleshooting mic problems.


Update Related Software

Sometimes microphone issues can arise if the apps or software using the microphone are out of date or incompatible. Check for any available updates to apps like Zoom, Skype, Discord, streaming software like OBS or XSplit, audio recording programs like Audacity, and other software that utilizes your microphone. Updating to the latest version can resolve bugs and improve microphone compatibility.

You can manually check each program’s website or application for updates. An easier option is to use a software update tool like Patch My PC to automatically detect and install available updates for many common programs. This ensures everything is updated and eliminates microphone problems caused by software conflicts.

If issues persist after updating, try reinstalling problematic apps or rolling back to previous versions that had working microphone access. As a last resort, uninstalling then reinstalling the app can reset any corrupted settings. Keeping software updated is an easy first troubleshooting step for microphone problems across various programs.

Try Microphone Alternatives

If your built-in microphone isn’t working properly, you may want to try using a microphone alternative instead. Here are some options to consider:

  • Microphone app – There are various microphone apps you can download that allow you to use your smartphone or tablet as a microphone. These connect via Bluetooth or WiFi and can provide an easy plug-and-play microphone solution.

  • USB microphone – A dedicated USB microphone can often provide better sound quality than a built-in mic. USB mics plug directly into your computer and work instantly without any driver installation required.

  • Headset – Headsets with an integrated microphone are a convenient option that allows you to both listen to audio and record voice input through the same device.

Trying an external microphone app, USB microphone, or headset can help determine if the issues you’re experiencing are due to a problem with your built-in mic specifically. If the microphone alternatives work properly, then the built-in mic may need service or replacement.

Reset Your Equipment

If your microphone is still not working properly after trying other troubleshooting steps, you may need to reset your equipment. Here are some reset options to try:

Restart your computer. A simple restart can help clear any software glitches that may be preventing your microphone from working. Shut down your computer completely, wait a few seconds, and then restart it to see if that fixes the issue.

Do a reset. Resetting your Windows operating system to factory default settings may resolve microphone problems. Back up your data first, then go to Settings > Update & Security > Recovery and choose Reset. This will reinstall Windows and your device drivers and settings.

Factory reset as a last resort. If you’ve tried everything else with no success, a factory reset that erases all data and fully reinstalls the operating system is the last option. Backup your data, then check your device guide for the key combination to press during bootup to initiate a factory reset. This will fully wipe your device and reinstall the OS.

Resetting your equipment may require reinstalling apps and drivers, but can get your microphone working again if other fixes don’t help. Just be sure to backup your data first.
