Complete Guide to Reactivating PC Audio: Step-by-Step Solutions

This guide will explain how to troubleshoot audio issues on your computer, whether you are using a Windows or macOS operating system. If you cannot hear sounds from your PC's internal or external speakers, you may need to review the audio card settings or update the related drivers. This problem can be caused by incorrect settings, corrupted drivers, or physical connection issues. By following the steps indicated, you can restore your computer's audio without needing to consult a technician, unless there are hardware malfunctions.

This guide is useful for technical users who want to independently resolve audio issues on their computer. It will guide you through preliminary checks, specific configurations for Windows 10 and later, and for macOS, as well as suggest solutions for persistent problems.

Prerequisites

• A computer with Windows 10 or later or macOS operating system
• Internet access to download any drivers or updates
• Cables to connect external speakers or headphones, if applicable
• External audio devices (speakers, headphones, Bluetooth headphones) to test the audio

Preliminary Operations and Checks

Before proceeding with troubleshooting the audio issue, perform the following preliminary checks:

• If you are using external speakers with a cable, ensure that all plugs are firmly connected to the computer, that the speakers are turned on, and that the volume is set to an appropriate level.
• If you are using external headphones, make sure they are turned on and that the battery is sufficiently charged.
• If you have connected audio devices via Bluetooth, check that they are correctly paired with the computer. Go to Settings > Bluetooth and Devices, Settings > Devices or Settings > Bluetooth and, if necessary, re-pair the Bluetooth headphones or speakers.
• Verify that the system volume is not muted. On Windows, click on the speaker icon near the clock and, if there is an X or a red circle, disable mute. Increase the volume by dragging the adjustment bar to the right. On Mac, open the Control Center, press the switches icon, locate the Sound box and drag the adjustment bar to the right to increase the volume.

How to Reactivate PC Audio: Windows 10 and Later

Check the Output Device

If you have connected external audio devices and the audio is not playing correctly, the wrong output device might be selected.

• Click on the volume icon near the system clock. On Windows 11, click on the regulators icon next to the volume bar. On Windows 10, click on the right angle arrow to the right of the volume adjustment bar.
• Alternatively, press the key combination Ctrl+Win+V to directly access the selector.
• Locate the Output Device box and ensure that the correct speaker is selected. If necessary, click on the device name to change it.
• Alternatively, open Windows Settings (click on the gear icon in the Start menu), go to System > Audio and choose the correct output device.

Check Mixer and Application Volume

If the audio is only playing from some programs, check the system mixer settings.

• Right-click on the volume icon near the clock and select Open Volume Mixer.
• On Windows 11, go to System > Audio > Volume Mixer.
• Locate the Apps list and ensure that there is no speaker icon with an X next to the program of interest. If present, click on it to reactivate the volume.
• Drag the audio adjustment bar corresponding to the software in question to the right to increase the volume.
• Click on the application name and verify that the output device is set correctly.
• On Windows 10, the system mixer appears as a panel above the application bar. Ensure that the speaker icon is not crossed out and that the volume is adequate.
• Also check the settings of the program in use to ensure that it has not been muted.

Check Device Status and Peripheral Drivers

If the problem persists, check the status of the audio peripheral and its related drivers.

• Open Device Manager by right-clicking on the Start button and selecting the corresponding option, or press Win+R, type devmgmt.msc and press Enter.
• Expand the Audio, Video, and Game Controllers section by clicking on the > symbol.
