• In the Oculus PC app, click Devices in the left menu
• Select the Quest headset
• Increase the “Encode Bitrate (Mbps)” slider
• Test if the increased bandwidth results in less crackling

Aim for 200-300mbps for lag-free wireless VR audio streaming.

8. Use a Different USB Port/Cable

For cabled Link users, try different USB 3 ports and cables to isolate bandwidth/interference issues:

• Switch to a direct USB port on the motherboard rear
• Test different high-quality Link cables
• Enable only the Link cable headset connection for isolation

Flaky USB ports or damaged Link cables can impact Oculus audio stability.

9. Repair/Reinstall Oculus Software

Corrupted Oculus software files or conflicts are a common source of audio glitches. Repairing or reinstalling the PC app often fixes this:

• Open the Oculus PC app settings
• Select General > Repair Software
• Alternatively, uninstall/reinstall the Oculus app completely

Repairing replaces corrupt files while reinstalling clears all conflicts and starts fresh.

10. Update Sound Drivers

You may need to update your Windows sound drivers from the motherboard manufacturer’s website. Audio driver bugs can sometimes manifest as Oculus crackling.

11. Disable Background Apps

Too many background apps and processes can overload resources needed for smooth VR audio:

• Close all non-essential apps with Task Manager before using Oculus
• Disable startup items that aren’t needed
• Set the Oculus app priority to High in Task Manager

Freeing up resources in this way prevents system overload and instability.

12. Contact Oculus Support

If you still can’t narrow down the cause, contact Oculus Support directly for troubleshooting assistance. Provide audio samples that demonstrate the crackling sounds. Support can diagnose if it’s a hardware fault covered under warranty or arrange a replacement headset if needed.

Following these tips should help eliminate any interference or software issues causing distorted Oculus Quest audio. But don’t hesitate to involve Oculus Support if problems persist. Immersive VR audio is key to enjoying Oculus Quest fully.

Why Does My Oculus Quest Have Crackling Audio?

Now that you know how to fix it, understanding potential causes provides more insight into resolving Oculus Quest audio problems for good.

Here are the most common culprits behind crackling and distorted sounds:
