How to Fix Microphone Crackling in Windows 10

Identify the symptom and environment

Start by noting when the microphone crackling appears. Record whether it happens in every app or only during a specific video call, recording tool, browser meeting or game. Also note whether the problem is present in a local recording or only for other participants in an online call. This distinction matters because a local recording uses the input device directly, while a call also depends on the network, the app and the output device.

Check the physical setup before changing software. Move the microphone cable away from power adapters, phone chargers and other cables. If the microphone has a detachable cable or connector, unplug it and reconnect it firmly without forcing the port. Crackling that changes when you touch or move the cable often points to a connection problem rather than a Windows setting.

Isolate where the fault occurs

Use a controlled test to separate the possible causes. Open the Voice Recorder app that is included with Windows 10, record a few seconds of speech, then play the recording back through headphones. If the recording is clean, the problem is more likely related to a particular app or call service. If the same crackling appears in the recording, continue testing the input path in Windows.

Next, test the input device in the same physical port and then in another port when one is available. A USB microphone can be connected to a different USB port, ideally one directly on the computer rather than a hub. An analog microphone can be tested through a different audio jack only if the computer has one and the connector type matches. Do not download or install a driver from an unknown source during this step.

Compare with another microphone if you have one. This can separate a problem with the microphone itself from a problem with the computer or the selected input. A second microphone is useful mainly for comparison, not as a repair by itself.

Try reversible fixes in order

Open Sound settings and check the input section. In Windows 10, select Start, then Settings, then System, then Sound. Under Input, confirm that the intended microphone is selected as the input device. Speak into the microphone and watch the input level indicator. If the level is consistently at the top of the scale, the signal may be clipping, which can sound like distortion or crackling.

Select Device properties under the input device and reduce the volume or input level. Start by lowering it in small steps, then use a short test recording after each change. A level that reaches the maximum only during louder speech can still clip briefly, so leave a small margin below the top of the indicator.

Check the sample rate and bit depth in the advanced properties for the microphone. Open the recording device properties through the Sound control panel, select the Advanced tab, and note the current format. If crackling appears only in a specific app, try a common setting such as a 48000 Hz sample rate, then test the app again. Be prepared to return to the previous value if there is no change.

Disable audio enhancements for the microphone if the option is present. In the device properties, open the Enhancements or Advanced tab and turn off any enabled enhancement. Some devices do not expose an Enhancements tab, and the available options vary by audio driver, so follow the labels shown on your computer rather than expecting a universal menu path.

If the microphone is connected through a hub, docking station or extension cable, connect it directly to the computer and repeat the test. Remove one variable at a time and keep a short note about what you changed, so you can restore any setting that does not help.

Confirm the result

Return to the same situation where the crackling originally appeared. If the issue happened in a video call, join a short test call or ask a contact to confirm whether the noise is gone. If it appeared in a recording, record another sample at a similar speaking volume and listen through the same output device.

Avoid using a factory reset or disabling broad security protections as a verification step. A change has worked when the original symptom is gone under conditions similar to the first failure, not when a new setting simply makes the microphone quieter or harder to hear.

If the problem remains

Keep a record of what you observed: the app or call service, the selected input device, the approximate input level, any ports and cables used, and whether the crackling appeared in local recordings. This information is useful if you contact the device manufacturer or a repair service.

A persistent crackle does not by itself prove that the microphone hardware has failed. Cable damage, a worn connector, interference from nearby equipment, app-specific settings or background noise can produce a similar symptom. If the microphone is clean in one app and not in another, focus on that app's audio settings and selection of input and output devices before replacing hardware.

Contact device support or a local repair service when the same microphone crackles in multiple apps, on different ports where available, and with the input level set to a moderate value. The recorded pattern of tests will help the technician avoid repeating steps you have already performed.
