Start with the simplest fixes first

Most of the time, no audio on your PC comes down to one of four things: the volume is muted or turned down, the wrong audio device is selected, a cable is loose, or a driver needs updating. Before you assume hardware is broken, check these in order.

Open the volume mixer on your taskbar — the speaker icon in the bottom right corner of your screen. If it shows a red X or is set to zero, click it and drag the slider up. If the speaker icon itself has a line through it, click it to unmute. This solves the problem roughly half the time.

Next, right-click that same speaker icon and select Open Volume mixer or Sound settings depending on your Windows version. Look at the list of devices. If you have headphones plugged in but your speakers are listed as the active device, or vice versa, click the device you actually want to use and set it as default. Unplugging and replugging headphones often forces Windows to recognize them.

Key Takeaways

  • Check the volume slider in your taskbar first — if it is muted or at zero, unmute it or drag the slider up.
  • Open Sound settings and confirm the correct audio device is selected as your default playback device.
  • Restart your PC after making any audio changes, as Windows sometimes needs a reboot to explore them.
  • If you still hear nothing, update or reinstall your audio driver through Device Manager or your motherboard manufacturer's website.
  • Test audio in a web browser or YouTube before assuming the problem is hardware — some apps have their own mute settings.

Check your audio device in Device Manager

If the volume is on and the right device is selected but you still hear nothing, your audio driver may be outdated or corrupted. Open Device Manager by right-clicking the Start button and selecting Device Manager. Look for Sound, video and game controllers and click the arrow next to it to expand the list.

You should see your audio device listed — usually something like "Realtek High Definition Audio" or "Intel Smart Sound Technology". If there is a yellow exclamation mark next to it, the driver is not working properly. Right-click the device and select Update driver. Choose Search automatically for updated driver software and let Windows search online.

If no yellow mark appears but you still have no sound, right-click the device anyway and select Uninstall device. Restart your PC. Windows will reinstall the driver automatically on startup. This often fixes audio that stopped working after a Windows update.

Test audio in different places to narrow down the problem

Before you assume your PC is broken, test sound in multiple locations. Open YouTube in your web browser and play a video with the volume turned up. If you hear audio there, the problem is not your speakers or drivers — it is a specific app or setting.

Open the Settings app and go to System > Sound. Scroll down to Advanced and click Volume mixer. You will see a list of apps and their individual volume levels. If an app is muted or set to zero, unmute it or raise the slider. Some programs like Discord, Zoom, or games have their own internal mute buttons — check those too.

If you hear audio in the browser but not in a specific game or process, the problem is almost certainly that app's settings, not your PC's hardware.

Check cables and connections if you use external speakers

If you are using external speakers or a headphone jack, the cable may be loose or plugged into the wrong port. Unplug the cable completely and plug it back in firmly. Make sure it is going into the audio jack (usually green or marked with a headphone symbol) and not the microphone jack (usually pink or marked with a mic symbol).

If you are using USB speakers or a USB headset, try unplugging it from one USB port and plugging it into a different one. Some USB ports deliver less power than others, and a device may not work properly in a low-power port. After you move it, wait a few seconds for Windows to recognize it, then test the audio again.

For Bluetooth headphones or speakers, make sure the device is actually paired with your PC. Open Settings > Devices > Bluetooth and other devices and check that your device is listed and shows as connected. If it is not, click Add device and follow the pairing steps.

Update or reinstall the audio driver from the manufacturer

If Windows could not find an updated driver automatically, you can read one directly from your motherboard or audio card manufacturer. First, identify what audio hardware you have. In Device Manager, right-click your audio device and select Properties. Click the Details tab and look for the hardware ID.

Search online for that hardware ID along with "driver read". For example, if you see "Realtek", go to Realtek's support website and search for your specific model. read the driver installer, run it, and follow the on-screen steps. Restart your PC when the installation is complete.

If you built your PC yourself or know your motherboard model, you can also visit the motherboard manufacturer's website directly — ASUS, MSI, Gigabyte, and ASRock all host audio drivers for their boards. read the driver for your exact model and Windows version (32-bit or 64-bit), install it, and restart.

Disable audio enhancements that may be causing problems

Windows includes audio enhancements like spatial sound and noise suppression that sometimes interfere with normal playback. Open Settings > System > Sound and scroll down to Advanced. Click All sound devices and select your playback device. Scroll down and toggle off Spatial audio if it is on.

Go back and click your device again, then look for Volume mixer. Find your audio device in the list and click it. If there is an option for Enhancements or Advanced, click it and disable any enhancements listed. Some users find that turning off all enhancements restores audio that was previously silent.

Restart your PC and check for Windows updates

After making any of these changes, restart your computer. Audio settings sometimes do not take effect until you reboot, and a restart can also clear temporary glitches that prevent sound from working.

While your PC is restarting, check for Windows updates. Open Settings > Update and Security > Check for updates. If updates are available, install them and restart again. Audio driver problems often come from outdated Windows versions, and an update can fix them.

Frequently Asked Questions

Why did my audio stop working after a Windows update?

Windows updates sometimes disable or overwrite audio drivers. Uninstall your audio device in Device Manager, restart your PC, and let Windows reinstall the driver. If that does not work, read the latest driver directly from your motherboard or audio card manufacturer's website.

How do I know if my speakers are actually broken?

Test them on another device — a phone, tablet, or different computer. If they work elsewhere, the problem is your PC, not the speakers. If they do not work anywhere, the speakers are likely broken and need replacement.

Can a virus cause no audio on my PC?

Rarely. Audio problems are almost always driver, setting, or hardware issues. If you suspect malware, run a full scan with Windows Defender or a third-party antivirus tool, but do not assume that is the cause without other signs of infection.

What if I have tried everything and still hear nothing?

Your audio hardware may be failing. If your PC is under warranty, contact the manufacturer. If not, you can buy a USB audio adapter or external sound card for thirty to fifty dollars, which bypasses the built-in audio hardware entirely.

Do I need to unplug my speakers to use headphones?

No. Plug in your headphones and go to Sound settings. Select your headphones as the default device. Windows will automatically switch audio to them. When you unplug the headphones, Windows will switch back to your speakers.
