How to Fix a Computer with No Sound

Expert Troubleshooting Guide by MicroSec™– Your Trusted Computer Repair Partner

Is your computer completely silent? You’re not alone. Many users face the dreaded “no sound on PC” issue at some point, and it can be frustrating, especially when you don’t know where to start.

Our experts at MicroSec™, your reliable computer repair service provider, break down the most effective ways to diagnose and fix sound issues. Whether it's a simple setting or a deeper hardware fault, we've got you covered.

1. Start with the Basics: Volume and Mute Settings

Before diving into advanced fixes, let’s rule out the simplest issue: muted or low volume.

• Click the speaker icon on your taskbar and check if it’s muted.

• Open the Volume Mixer and ensure no apps are individually muted.

• If you're using external speakers or headphones, confirm that they are powered on and their volume is up.

Often, “no sound from the computer” can be fixed with just a few clicks here.

2. Check the Audio Output Device

One of the most common causes of a computer's sound not working is the wrong audio output device being selected.

On Windows:

• Right-click the speaker icon and go to Sound Settings.

• Under “Choose your output device,” make sure the correct one is selected (e.g., Speakers or Headphones).

On Mac:

• Navigate to System Settings → Sound → Output.

• Choose the appropriate output device.

Switching to the correct output often fixes the no sound on PC issue instantly.

3. Inspect All Physical Connections

Physical problems can be surprisingly common:

• Ensure your speakers or headphones are properly connected to the right port (usually green for output).

• Check for any signs of wear on your cables.

• If you're using USB or Bluetooth audio devices, make sure they’re properly paired and recognized by your computer.

Testing your device on another PC can also help isolate the problem.

4. Restart the Audio Services

Restarting your system and audio services can often fix temporary glitches.

• Reboot your PC.

• On Windows, press Win + R, type services.msc, and press Enter.

• Find Windows Audio, right-click it, and choose Restart.

This step can solve many cases of “computer no sound” caused by temporary software issues.

5. Run the Built-in Troubleshooter

If your sound is not working on the computer, let your OS help:

• On Windows, go to Settings → System → Sound and click on Troubleshoot.

• Follow the on-screen prompts to identify and fix the issue.

The built-in troubleshooter often detects muted settings, incorrect configurations, or driver issues.

6. Update or Reinstall Audio Drivers

Corrupt or outdated drivers are a major cause of no sound from computer issues.

• Open Device Manager.

• Expand the Sound, Video, and Game Controllers section.

• Right-click on your audio device and choose Update Driver.

• If updating doesn’t work, try uninstalling the Device and restarting your PC to auto-reinstall it.

• If the problem started after a driver update, choose Roll Back Driver in the device properties.

This method can fix sound problems on PCs where software conflicts are the root cause.

7. Disable Audio Enhancements

Some built-in sound enhancements can interfere with normal playback:

• Right-click on the audio device in Sound Settings → go to Properties.

• Navigate to the Enhancements tab.

• Check Disable all enhancements.

• Test different audio formats under the Advanced tab.

This is particularly helpful when the computer sound is not working even though the settings appear correct.

8. Check BIOS or UEFI Settings

In rare cases, internal sound can be disabled from the BIOS:

• Restart your PC and enter BIOS or UEFI settings (usually by pressing F2, Del, or Esc).

• Navigate to Integrated Peripherals or a similar tab.

• Ensure Onboard Audio is enabled.

Incorrect BIOS settings can silently disable your entire sound system.

9. Try a Clean Boot or New User Profile

Sometimes third-party software interferes with your audio.

• Create a new user account and check if the sound works.

• Perform a Clean Boot to start your PC with only essential services.

This helps identify if the issue is software-related or tied to your main user profile.

10. Hardware Issues – When to Call a Pro

If nothing else has worked, you might be facing a hardware issue:

• Test your PC with another set of speakers or headphones.

• For desktops, open the case (if you're comfortable) and ensure the sound card is properly seated.

• Look for any signs of damage or burnt components.

• Use compressed air to remove dust.
