No Sound After Windows 10 Install? Fix It

If you installed Windows 10 and now have no sound, the fix is usually updating or reinstalling your audio driver, but first check the basics like volume levels and the default playback device. This guide walks through the most common causes and step-by-step solutions, from quick checks to driver reinstallation, so you can get audio back quickly.

Why Sound Disappears After a Windows 10 Install

When you install Windows 10 fresh or upgrade from an older version, the operating system brings its own generic drivers. These generic drivers may not fully support your specific sound card or onboard audio chip, leading to no sound at all. Another common cause is that Windows sets the wrong default playback device, especially if you have multiple audio outputs like HDMI, USB headphones, or Bluetooth speakers. Sometimes the audio service (Windows Audio) fails to start, or the sound card itself is disabled in Device Manager.

Quick Checks Before Diving Into Drivers

Start with the simplest things, because they cause the problem more often than you’d think:

• Check the volume icon in the system tray – make sure it’s not muted and the volume is up.
• Right-click the volume icon and select “Open Volume mixer” – ensure the app you’re using isn’t muted individually.
• If you’re using speakers or headphones, verify they’re plugged into the correct jack (usually the green one) and that they work on another device.
• Try a different audio output, like front panel vs. rear panel jacks, or switch from speakers to headphones.

If these don’t help, move on to the more technical fixes.

Set the Correct Default Playback Device

Windows 10 often picks the wrong device as the default, especially after an update. To fix this:

1. Right-click the speaker icon in the system tray and choose “Open Sound settings”.
2. Under “Output”, you’ll see a dropdown for “Choose your output device”. Select your speakers or headphones.
3. Click “Manage sound devices” to see all devices. If your device is listed as disabled, click it and select “Enable”.
4. Also, go to the classic Control Panel > Sound > Playback tab. Right-click your desired device and choose “Set as Default Device”. Then right-click and choose “Test” to see if you hear sound.

If your device isn’t listed at all, it means the driver isn’t installed or the hardware isn’t detected – proceed to the driver steps below.

Update or Reinstall the Audio Driver

Drivers are the most common culprit. Windows 10 may have installed a generic driver that doesn’t work with your audio hardware. Here’s how to fix it:

1. Right-click the Start button and select “Device Manager”.
2. Expand “Sound, video and game controllers”. Look for your audio device – it may have a yellow exclamation mark.
3. Right-click the device and select “Update driver”. Choose “Search automatically for updated driver software”. If Windows finds a new driver, it will install it.
4. If that doesn’t work, right-click again and select “Uninstall device”. Check the box “Delete the driver software for this device” if available, then restart your PC. Windows will reinstall the driver automatically on boot.
5. If Windows doesn’t find a better driver, go to your computer or motherboard manufacturer’s website, download the latest audio driver for your model, and install it manually.

After reinstalling, restart your PC and test the sound.

Restart the Windows Audio Service

The Windows Audio service manages all audio on your system. If it’s not running, you’ll have no sound even with correct drivers. To restart it:

1. Press Win + R, type services.msc, and press Enter.
2. Scroll down to “Windows Audio”. Right-click it and select “Restart”. If it’s not running, right-click and select “Start”.
3. Also check “Windows Audio Endpoint Builder” – it should be running. If not, start it.
4. Set both services to “Automatic” by right-clicking > Properties > Startup type.

This often resolves issues where the audio service crashed after installation.

Run the Built-in Audio Troubleshooter

Windows 10 has a built-in troubleshooter that can automatically detect and fix common audio problems. To run it:

1. Go to Settings > Update & Security > Troubleshoot > Additional troubleshooters.
2. Select “Playing Audio” and click “Run the troubleshooter”.
3. Follow the on-screen prompts. It will check for issues and may apply fixes automatically.

This is a safe first step, but it doesn’t always solve driver-related problems, so don’t be discouraged if it doesn’t work.

Common Misconception: “It’s a Hardware Problem”

Many people assume their sound card is dead when they get no sound after an install. In reality, it’s almost always a driver or configuration issue. Before buying new hardware, try booting from a live Linux USB – if sound works there, your hardware is fine and the issue is purely Windows software. This is a quick way to confirm the problem isn’t physical.

Frequently Asked Questions

Why is there no sound after upgrading to Windows 10 from Windows 7/8?

Upgrades often carry over old drivers that don’t work with Windows 10. The fix is to uninstall the old driver in Device Manager and let Windows install a fresh one, or download the latest driver from the manufacturer’s website.

My audio device is not showing in Device Manager at all. What do I do?

This usually means the hardware isn’t detected. Try reseating the sound card (if it’s a desktop) or checking if the onboard audio is enabled in the BIOS. Also, check if the device appears under “Other devices” as an unknown device – if so, right-click and update the driver.

I have sound through HDMI but not from speakers. How do I fix it?

This is a classic default device issue. Go to Sound settings and set your speakers (not the HDMI output) as the default device. If the speakers don’t appear, you may need to disable the HDMI device temporarily or install the correct audio driver for your motherboard.

Will reinstalling Windows 10 fix the sound issue?

If the problem is software-related, a clean install can help, but it’s a last resort. Try all the steps above first, as they are less disruptive and often effective. A clean install will also require you to reinstall all your drivers and programs.

Why does my sound work after restart but then stop?

This could be a driver conflict or a power management issue. Go to Device Manager, right-click your audio device, select Properties > Power Management, and uncheck “Allow the computer to turn off this device to save power”. Also, check for driver updates from the manufacturer.

Is there any risk in uninstalling the audio driver?

No, uninstalling the driver is safe. Windows will either reinstall a generic driver automatically or you can install the correct one from the manufacturer. Your hardware won’t be damaged.
