Few things are more frustrating than sitting down to watch a video or join a meeting—only to realize your computer has no sound. Whether you’re using Windows 10, Windows 11, or a desktop from Dell, HP, or Lenovo, this guide will walk you through every proven fix to restore your audio.
🎧 Step 1: Check the Basics
Before diving into advanced troubleshooting, start simple:
- Verify your volume isn’t muted.
- Click the 🔊 speaker icon in the taskbar and make sure the slider isn’t all the way down.
- Check your physical connections.
- Ensure your speakers or headphones are plugged into the correct jack or USB port.
- Test with another device.
- Try your headphones or speakers on another PC or phone to confirm they work.
💡 Tip: Bluetooth devices often disconnect automatically—re-pair them in Settings → Bluetooth & Devices.
🧩 Step 2: Run the Windows Audio Troubleshooter
Windows includes a built-in tool that can automatically detect and fix sound problems.
On Windows 11:
- Press Windows + I to open Settings.
- Go to System → Troubleshoot → Other troubleshooters.
- Find Playing Audio and click Run.
On Windows 10:
- Open Settings → Update & Security → Troubleshoot.
- Select Playing Audio → Run the troubleshooter.
Windows will scan your audio system and apply fixes automatically.

🔊 Step 3: Make Sure the Right Playback Device Is Selected
Sometimes your PC sends sound to the wrong device (e.g., a disconnected monitor or HDMI port).
- Right-click the speaker icon → select Sound settings.
- Under Output, choose your preferred device (e.g., “Speakers (Realtek Audio)” or “Headphones”).
- Test the sound again.
If you’re using multiple monitors, check that the correct HDMI or DisplayPort output is selected.
🧠 Step 4: Update or Reinstall Your Audio Drivers
Outdated or corrupted drivers are a common cause of audio failure.
To update:
- Press Windows + X → select Device Manager.
- Expand Sound, video and game controllers.
- Right-click your sound device → choose Update driver → Search automatically.
To reinstall:
- Right-click your sound device → Uninstall device.
- Restart your PC—Windows will reinstall the correct driver automatically.
If that doesn’t work, download the latest driver from your manufacturer’s website (e.g., Realtek, Intel, Dell, or HP).

- Under Advanced, make sure the default format is set correctly (e.g., 24-bit, 48000 Hz).
Click Test to verify your speakers are working.
⚙️ Step 6: Restart Audio Services
Sometimes Windows audio services stop running in the background.
- Press Windows + R, type
services.msc, and hit Enter. - Find these three services:
- Windows Audio
- Windows Audio Endpoint Builder
- Remote Procedure Call (RPC)
- Right-click each → Restart.
- Reboot your PC and test again.
