How to Fix Crackling or Popping Sound on Windows 11

The Problem

Your speakers or headphones crackle, pop, or stutter—often worse during video calls, games, or when the CPU is busy. The audio itself isn't damaged; this is usually a sample-rate mismatch, an "enhancement" effect, or driver latency (DPC) stealing time from the audio buffer.

No sound at all rather than crackling? Start with no audio on Windows 11. Sound coming from the wrong device? See headphones using the wrong audio output.

Quick Fixes (Try These First)

Run the Audio Troubleshooter

Settings → System → Sound → Troubleshoot common sound problems (next to Output). Apply what it finds.

Try a Different Cable or Port

A loose 3.5mm jack or a flaky USB port causes textbook crackle. Reseat the connector or move USB audio to a rear port directly on the motherboard.

The Fix: Step-by-Step

Step 1: Change the Sample Rate

A mismatched rate is the most common cause of crackling.

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

Step 2: Turn Off Audio Enhancements

  1. In the same device page, find Audio enhancements and set it to Off.
  2. On older driver panels: open mmsys.cpl → your device → Properties → Enhancements tab → tick Disable all enhancements.

Step 3: Disable Exclusive Mode

  1. Open the classic Sound control panel (Win + R → mmsys.cpl).
  2. Double-click your playback device → Advanced tab.
  3. Untick Allow applications to take exclusive control of this device → OK.

Step 4: Set Minimum Processor State to 100%

Aggressive CPU throttling starves the audio buffer.

  1. Control Panel → Power Options → Change plan settings → Change advanced power settings.
  2. Expand Processor power management → Minimum processor state → set to 100% (at least while testing).

Step 5: Update or Roll Back the Audio Driver

  1. Right-click Start → Device Manager → expand Sound, video and game controllers.
  2. Right-click your audio device (e.g. Realtek Audio) → Update driver.
  3. If crackling started right after a driver update, choose Properties → Driver tab → Roll Back Driver instead.

Step 6: Find the Latency Culprit

If only certain hardware causes it, a driver is the cause.

  1. Open Device Manager → Network adapters.
  2. Temporarily Disable Wi-Fi or Bluetooth one at a time and test—Bluetooth and some Wi-Fi drivers are classic latency offenders.
  3. Update whichever device clears the crackle.
