How to Fix Hollow Knight Audio Not Working or Crackling Sound: Step-by-Step

1. Restart Your Game and System

The first and simplest step is to restart:

  • Exit Hollow Knight completely and relaunch the game.

  • Toggle the audio settings off and on again to reset.

  • If available, try switching between Stereo and Surround sound modes.

3. Verify Windows Default Audio Output Device

Incorrect audio output selection can cause no sound or crackling:

  • On Windows, right-click the sound icon in the taskbar and select Open Sound settings.

  • Under Output, confirm the correct playback device is selected (speakers, headphones, or HDMI audio).

  • If multiple audio devices are connected, unplug unused devices or disable them temporarily in Sound Control Panel → Playback tab.

  • Test your system sound outside the game to confirm the device is working.

4. Update or Reinstall Audio Drivers

Outdated or corrupt audio drivers are a major cause of sound issues:

  • Open Device Manager (Windows + X → Device Manager).

  • Expand Sound, video and game controllers.

  • Right-click your audio device and select Update driver → Search automatically for updated drivers.

  • If no updates are found, uninstall the device (right-click → Uninstall device) and restart your PC. Windows will reinstall drivers automatically.

  • Alternatively, download the latest drivers from your audio device or motherboard manufacturer’s website.

5. Disable Audio Enhancements and Exclusive Mode

Windows audio enhancements or exclusive mode can cause crackling or distorted sound:

  • Right-click the speaker icon → Open Sound settings → Sound Control Panel on the right side.

  • In the Playback tab, right-click your default audio device and select Properties.

  • Go to the Enhancements tab and check Disable all enhancements (if available).

  • In the Advanced tab, uncheck Allow applications to take exclusive control of this device and Give exclusive mode applications priority.

  • Click OK and restart Hollow Knight.

6. Adjust Audio Sample Rate and Bit Depth

Mismatched audio sample rates between Windows and your hardware can cause crackling:

  • In the Advanced tab of your audio device properties (from the previous step), try setting the Default Format to a standard rate like 24 bit, 44100 Hz (Studio Quality) or 16 bit, 48000 Hz (DVD Quality).

  • Test each setting until crackling or audio issues disappear.

7. Disable Background Applications and Overlays

Programs running in the background can interfere with game audio:

  • Close any audio-related programs such as Discord, Teamspeak, OBS, or recording software while playing.

  • Disable overlays like Steam Overlay, Discord Overlay, or Nvidia GeForce Experience overlay as these can cause audio lag or crackling.

  • Temporarily disable antivirus or firewall software to test for interference.

8. Verify Integrity of Game Files on Steam

Corrupt or missing game files can cause audio problems:

  • Open Steam → Library → Right-click Hollow Knight → Properties → Local Files → Verify integrity of game files.

  • Steam will scan and fix any issues.

9. Update Your Console’s System Software and Audio Settings

If you’re playing on PS4, PS5, or Xbox, ensure your system software is updated:

  • Check for the latest firmware updates for your console and install them.

  • Review your console’s audio output settings, making sure the correct audio device (TV speakers, headset, soundbar) is selected.

  • Disable audio passthrough or surround sound if you’re experiencing crackling or no audio.

10. Check Hardware Connections

Loose or damaged cables can cause crackling and audio dropouts:

  • Inspect your headphone jack, speaker cables, and HDMI connections.

  • Try using different headphones or speakers to isolate hardware issues.

  • Avoid using cheap or faulty audio adapters.

11. Lower In-Game Graphics Settings or Background CPU Load

Sometimes high CPU or GPU load can cause audio glitches:
