Symptoms
- Audio pops or crackles during playback
- Sound distorts at higher volumes
- Crackling happens only with certain apps or Bluetooth
- Crackling started after a Windows update
Likely causes
- CommonAudio driver glitch or needs updatingA buggy or outdated driver is one of the most common causes of crackling on both built-in and external speakers.
- CommonVolume or equalizer settings pushing audio too hotVolume boosted past 100% in software or heavy bass settings can cause distortion.
- CommonLoose speaker or headphone jack connectionA partially inserted plug or worn jack can cause intermittent crackling.
- PossibleBluetooth interference or low signalWireless speakers/headphones can crackle when the connection is weak or congested.
- Less commonDamaged speaker cone or amplifierPhysically damaged speakers can produce ongoing distortion regardless of settings.
What to do
- Lower the system and app volume to around 70–80% and see if crackling reduces, since over-amplified audio commonly distorts.
- Update or reinstall the audio driver via Device Manager or the manufacturer's website.
- Check and reset any audio enhancement or equalizer settings to default/flat.
- If using a wired connection, unplug and firmly reseat the cable, checking for a full connection.
- For Bluetooth, move closer to the computer and reduce nearby wireless interference.
- Test with different audio sources (music, video, a different app) to see if the crackling is consistent or specific to one source.
- Test with headphones or another speaker to isolate whether it's the speaker hardware or the computer's audio output.

When to call a pro
If crackling continues across multiple audio sources and after a driver reinstall, and other speakers/headphones sound fine on the same computer, the original speaker hardware has likely failed.
