Summary: Audio crackling, popping, or stuttering on Windows 11? Fix the sample rate, turn off audio enhancements, and stop the driver latency behind the static.
Recommended app: PC-Troubleshooter — https://www.mytechnician.tech/apps/windows-troubleshooter/ (Microsoft Store: https://apps.microsoft.com/detail/9N7RWKW8SP24?hl=en-us&cid=mytechnician-web). Optional; every step below uses built-in Windows tools.

## The Problem
Speakers or headphones crackle, pop, or stutter—often worse during video calls, in games, or whenever the CPU is busy. The audio hardware is rarely damaged. This is a sample-rate mismatch, an enhancement effect, or driver latency stealing time from the audio buffer.

> **No sound at all rather than crackling?** Start with [no audio on Windows 11](https://www.mytechnician.tech/tips/fix-no-audio-windows-11/). **Sound from the wrong device?** See [headphones using the wrong audio output](https://www.mytechnician.tech/tips/fix-headphones-wrong-audio-output-windows-11/).

## Step 1: Rule Out the Cable and Port
Two minutes that save an hour of software work.

* Reseat the 3.5 mm jack fully. A plug sitting one click out produces textbook crackle.
* Move a USB DAC or headset to a **rear** motherboard port, not a front panel or hub.
* Try different headphones or speakers on the same PC, and the same headphones on a phone.
* Route the cable away from the power supply and monitor cables—analogue audio picks up interference easily, and a crackle that changes when you move the mouse or scroll is electrical noise, not software.

## Step 2: Change the Sample Rate
A mismatch between the format Windows sends and what the device expects is the single most common software cause.

1. Right-click the speaker icon → **Sound settings**.
2. Click your output device.
3. Scroll to **Format** and set **24 bit, 48000 Hz (Studio Quality)**. Test.
4. If it still crackles, try **16 bit, 44100 Hz (CD Quality)**, then **16 bit, 48000 Hz**.

Higher is not better here. Integrated audio pushed to 24-bit 192 kHz is a well-known cause of crackling on hardware that cannot sustain it.

## Step 3: Turn Off Audio Enhancements
1. On the same device page, set **Audio enhancements** to **Off**.
2. On older driver panels: `Win + R` → `mmsys.cpl` → your device → **Properties** → **Enhancements** tab → tick **Disable all enhancements**.
3. Also disable **Spatial sound** (Windows Sonic, Dolby Atmos) while testing.

## Step 4: Disable Exclusive Mode
1. `Win + R` → `mmsys.cpl` → **Playback** tab.
2. Double-click your device → **Advanced** tab.
3. Untick **Allow applications to take exclusive control of this device** and **Give exclusive mode applications priority**.
4. **OK**.

This matters most when a game or DAW grabs the device at a different rate than everything else is using.

## Step 5: Stop the CPU From Dropping Too Low
Aggressive power saving starves the audio buffer, which is why crackling is often worse on battery.

1. **Control Panel** → **Power Options** → **Change plan settings** → **Change advanced power settings**.
2. Expand **Processor power management** → **Minimum processor state** → set **100%** on both **On battery** and **Plugged in** while testing.
3. Set the power mode to **Best performance** in **Settings** → **System** → **Power & battery**.

If this fixes it, the cause is latency—continue to Step 7 to find the responsible driver rather than leaving the CPU pinned high permanently.

## Step 6: Update or Roll Back the Audio Driver
1. **Device Manager** → **Sound, video and game controllers**.
2. Right-click your audio device → **Update driver**.
3. If crackling started right after an update: **Properties** → **Driver** → **Roll Back Driver**.
4. For Realtek, prefer the package from your motherboard or laptop maker over the generic Microsoft one.

## Step 7: Find the Latency Culprit (DPC)
Crackling that comes and goes, or coincides with network activity, is caused by a driver holding the CPU too long.

Install **LatencyMon**, run it for five to ten minutes while reproducing the crackle, and read which driver reports the highest DPC execution time. The repeat offenders:

* **Wi-Fi drivers** (Intel and Killer especially)
* **Bluetooth**
* **Network adapters** with Energy Efficient Ethernet enabled
* **Storage controller** drivers
* **GPU drivers**

Test by disabling one at a time in Device Manager. When you find it, update that specific driver rather than leaving the hardware disabled. Related symptom set: [DPC_WATCHDOG_VIOLATION](https://www.mytechnician.tech/tips/fix-dpc-watchdog-violation-windows-11/).

## Step 8: Fix Adapter Power Settings
1. **Device Manager** → **Network adapters** → your adapter → **Properties**.
2. **Power Management** → untick **Allow the computer to turn off this device to save power**.
3. **Advanced** → disable **Energy Efficient Ethernet** / **Green Ethernet** if present.

Do the same for USB Root Hubs if the crackle affects a USB audio device.

## Bluetooth Specifically
Crackling over Bluetooth is usually bandwidth or codec related rather than a Windows fault.

* Move closer to the PC and away from USB 3.0 devices, which emit interference right in the 2.4 GHz band.
* If the mic is active, Windows drops to the hands-free profile and audio quality falls sharply—that is expected, not a fault.
* Set the stereo playback device rather than the hands-free one as default in `mmsys.cpl`.
* See [fix Bluetooth not working](https://www.mytechnician.tech/tips/fix-bluetooth-not-working-windows-11/).

## Still Crackling?
* Test with a cheap USB DAC. If USB audio is clean while the 3.5 mm jack crackles, the motherboard's analogue stage is the fault and a USB adapter is a permanent fix for a few pounds.
* Heavy background load contributes—see [speed up a slow Windows 11 PC](https://www.mytechnician.tech/tips/speed-up-slow-windows-pc/) and [fix 100% CPU usage](https://www.mytechnician.tech/tips/fix-100-percent-cpu-usage-windows-11/).
* Run `sfc /scannow` and `DISM /Online /Cleanup-Image /RestoreHealth` if the audio stack itself seems damaged.
