Experiencing no audio and high CPU usage issues in Windows 10 Build 15007 can be frustrating. These problems often affect your computer’s performance and overall experience. Fortunately, there are straightforward ways to fix them.

This guide will walk you through simple and effective steps to resolve these bugs. Each step is explained in an easy-to-understand manner, even if you are new to Windows troubleshooting.

By following this article, you’ll learn how to identify and fix the root causes of these problems. Let’s get started with some quick checks before diving into detailed solutions.

Fixing these issues will help your PC run smoothly and restore your audio functionality.

Quick Note Before You Begin

Before troubleshooting, make sure to check the following:

  • Windows version: Confirm you are on Build 15007 by pressing Win + R, typing winver, and pressing Enter.
  • Audio hardware: Ensure your speakers or headphones are properly connected and powered on.
  • Basic reboot: Restart your PC to clear temporary glitches.
  • Updates: Check if any Windows updates are pending as they can include important fixes.

Now, let’s move on to step-by-step solutions.

Step 1: Restart Audio Services

Windows uses specific services to manage audio. Sometimes, these services can stop working properly and cause no sound or high CPU usage.

  1. Press Win + R to open the Run dialog.
  2. Type services.msc and hit Enter.
  3. In the list, find Windows Audio and Windows Audio Endpoint Builder.
  4. Right-click on each service and select Restart.
  5. If any service is not running, right-click and select Start.

Why this helps: Restarting these services refreshes the audio system and can fix temporary bugs causing no sound or abnormal CPU load.

Step 2: Update or Reinstall Audio Drivers

Outdated or corrupted audio drivers are a common cause of audio problems and CPU spikes.

  1. Right-click the Start button and choose Device Manager.
  2. Expand the Sound, video and game controllers section.
  3. Right-click your audio device (e.g., Realtek High Definition Audio) and select Update driver.
  4. Choose Search automatically for updated driver software.
  5. If no update is found, you can try uninstalling the driver by clicking Uninstall device, then restart your PC. Windows will reinstall the driver automatically.

Why this helps: Drivers act as a bridge between hardware and software. Keeping them updated ensures compatibility and efficiency, preventing bugs.

Step 3: Disable Audio Enhancements

Sometimes, audio enhancements can cause conflicts, leading to no sound or excessive CPU use.

  1. Right-click the speaker icon in the system tray and select Sounds.
  2. Go to the Playback tab, select your default playback device, and click Properties.
  3. Navigate to the Enhancements tab.
  4. Check the box labeled Disable all enhancements or uncheck individual effects.
  5. Click Apply and then OK.

Why this helps: Audio enhancements can sometimes cause problems with driver compatibility and CPU processing.

Step 4: Run the Audio Troubleshooter

Windows 10 includes a built-in troubleshooter that automatically detects and fixes audio problems.

  1. Open Settings by pressing Win + I.
  2. Go to Update & Security > Troubleshoot.
  3. Select Additional troubleshooters.
  4. Click on Playing Audio and then Run the troubleshooter.
  5. Follow the on-screen instructions and apply any suggested fixes.

Why this helps: The troubleshooter scans for common issues and applies automatic repairs.

Step 5: Check for Background Processes Using High CPU

High CPU usage can be caused by apps or processes that conflict with audio services.

  1. Press Ctrl + Shift + Esc to open Task Manager.
  2. Click the Processes tab.
  3. Sort by CPU usage by clicking the CPU column header.
  4. Identify processes consuming unusually high CPU.
  5. If you find suspicious or unknown apps, right-click and choose End task.

Why this helps: Ending resource-heavy processes can relieve CPU load and stabilize audio performance.

Advanced Option: Reset Windows Audio Components

If the above steps do not fix the issue, you can reset Windows audio components using Command Prompt.

  1. Press Win + X and select Windows PowerShell (Admin) or Command Prompt (Admin).
  2. Type the following commands one by one, pressing Enter after each:
net stop audiosrv
net stop AudioEndpointBuilder
net start audiosrv
net start AudioEndpointBuilder

This will stop and restart audio-related services forcefully.
