This guide will walk you through the most effective solutions, starting with the simplest checks and moving to more advanced steps, to get your sound back.

First, a Few Basic Checks (Don’t Skip These!)
Before diving into complex fixes, let’s rule out the simple stuff. It might sound obvious, but these quick checks solve the problem more often than you’d think.
- Check Your Volume: Click the speaker icon in the bottom-right corner of your taskbar. Make sure the volume slider isn’t at zero and that the speaker icon doesn’t have an ‘X’ next to it, which indicates it’s muted.
- Check Your Physical Connections: If you use external speakers or a headset, ensure the cables are securely plugged into the correct audio port on your computer. Try unplugging and plugging them back in.
- Select the Correct Playback Device:
- Right-click the speaker icon in the taskbar.
- Select Open Sound settings (or Sound settings).
- Under the Output section, you’ll see a dropdown menu for “Choose your output device.”
- Make sure your desired speakers or headphones are selected. Sometimes, a Windows update can switch this to a monitor or another connected device that doesn’t have speakers.
If these basic checks don’t work, it’s time to move on to the more technical fixes.

Method 1: Use the Built-in Windows Audio Troubleshooter

- Right-click the speaker icon in the taskbar.
- Select Troubleshoot sound problems.
- The troubleshooter will launch and ask you to select the device you’re having issues with. Choose your speakers or headphones and click Next.
- Follow the on-screen instructions. The tool will check for common issues with volume settings, services, and audio drivers and attempt to fix them for you.
Method 2: Fix Your Audio Drivers
The most common cause for sound not working after an update is a problem with the audio driver. The update may have installed a generic driver that doesn’t work well with your specific hardware. We’ll use Device Manager for this.
