Mastering Your Audio: A Comprehensive Guide to Changing Input and Output Audio on Any Device

Changing your audio input and output is a fundamental skill for anyone using a computer, phone, or tablet. Whether you’re switching from internal speakers to headphones, selecting the right microphone for a conference call, or troubleshooting sound issues, understanding how to manage your audio devices is essential. The process varies slightly depending on your operating system and device, but the underlying principles remain the same.

How to Quickly Change Your Audio Input and Output

The quickest way to change your audio input (microphone) and audio output (speakers, headphones) is usually through your device’s system settings. Here’s a general guide:

Windows: Go to Settings > System > Sound. Under “Output,” choose your desired output device. Under “Input,” select your preferred input device.
macOS: Go to System Preferences > Sound. In the “Output” tab, select your output device. In the “Input” tab, choose your input device.
Android: Go to Settings > Connections > Bluetooth (if using Bluetooth devices). Tap the settings icon next to your connected device, then select Audio output to choose your desired output. For input, you usually don’t have a direct setting unless using external microphones which the device will auto-detect. Otherwise, it will use the built-in microphone. Some applications allow you to select the microphone within the app settings.

Let’s delve deeper into the specific steps for each major platform.

Changing Audio Input and Output on Windows

Windows offers several ways to manage your audio devices, giving you flexibility and control over your sound settings.

Using the Settings App

Open the Settings app: Click the Start button, then click the Gear-shaped Settings icon.
Navigate to Sound Settings: Go to System > Sound.
Choose Your Output Device: Under the Output section, use the dropdown menu labeled “Choose your output device” to select the speakers, headphones, or other audio output device you want to use. You can adjust the volume using the slider below the device selection.
Choose Your Input Device: Under the Input section, use the dropdown menu labeled “Choose your input device” to select the microphone or other audio input device you want to use. You can test your microphone by speaking into it and observing the input level indicator.

Using the Sound Control Panel

The Sound Control Panel offers more advanced options for configuring your audio devices.

Open the Control Panel: Type “Control Panel” in the Windows search bar and click on the app in the results.
Open Sound Settings: Make sure “View by” is set to “Large icons” or “Small icons” in the upper right corner, then click on “Sound“.
Manage Playback Devices: In the Playback tab, you’ll see a list of all your output devices. Right-click on the device you want to use as your default and select “Set as Default Device“. You can also set a separate device as the “Default Communication Device” for voice chat applications.
Manage Recording Devices: In the Recording tab, you’ll see a list of all your input devices. Right-click on the device you want to use as your default and select “Set as Default Device“. You can also set a separate device as the “Default Communication Device“.

Troubleshooting Audio Problems on Windows

If you’re experiencing audio problems, here are a few troubleshooting steps to try:

Check Device Connection: Ensure your speakers, headphones, or microphone are properly connected to your computer.
Update Drivers: Outdated or corrupted audio drivers can cause problems. Go to Device Manager (search for it in the Windows search bar), expand “Sound, video and game controllers“, right-click on your audio device, and select “Update driver“.
Run the Audio Troubleshooter: Windows has a built-in audio troubleshooter that can automatically detect and fix common problems. Go to Settings > System > Sound > Troubleshoot.
Check Volume Mixer: The Volume Mixer allows you to adjust the volume for individual applications. Right-click on the speaker icon in the system tray and select “Open Volume Mixer” to check if any applications are muted or have their volume turned down.

Changing Audio Input and Output on macOS

macOS offers a streamlined approach to managing audio devices.

Using System Preferences

Open System Preferences: Click the Apple icon in the menu bar and select “System Preferences“.
Open Sound Settings: Click on “Sound“.
Choose Your Output Device: In the Output tab, select your desired output device from the list. Adjust the output volume using the slider.
Choose Your Input Device: In the Input tab, select your desired input device from the list. Adjust the input volume using the slider. You can also monitor the input level to ensure your microphone is working correctly.

Using Audio MIDI Setup

For more advanced audio configuration, macOS provides the Audio MIDI Setup utility.

Open Audio MIDI Setup: Go to Applications > Utilities > Audio MIDI Setup.
Configure Devices: In the Audio Devices window, you can configure the input and output settings for your audio devices, including sample rate, bit depth, and channel configuration.

Troubleshooting Audio Problems on macOS

Check Device Connection: Make sure your audio devices are properly connected.
Restart Your Mac: Sometimes a simple restart can resolve audio issues.
Check the Volume: Ensure the volume is not muted and is set to an audible level.
Update macOS: Keeping your operating system up to date can resolve compatibility issues.
Reset NVRAM/PRAM: Resetting NVRAM/PRAM can sometimes fix audio problems. Restart your Mac and immediately press and hold the Option, Command, P, and R keys until you hear the startup sound a second time.

Changing Audio Output on Android

Android provides a simplified approach to audio management, primarily focused on output devices. Input is usually handled by the system default unless you configure otherwise within specific apps.

Using Settings

Open the Settings App: Locate and open the Settings app on your Android device.
Navigate to Connections: Tap on “Connections” (or a similar option depending on your Android version and manufacturer).
Access Bluetooth Settings (If Applicable): If you’re using Bluetooth headphones or speakers, tap on “Bluetooth“.
Configure Audio Output: Find your connected Bluetooth device and tap the Settings icon (usually a gear icon) next to it. You might find an “Audio output” option that allows you to select where the audio is directed. On some Android versions, simply connecting a Bluetooth device automatically redirects the audio output.
Check App Settings Some audio apps give you control over audio routing. Open the app’s settings and look for audio input and output settings.

Audio Input

Most Android devices will automatically select the appropriate microphone (built-in or headset) when an app requests audio input. Check the application permissions to be sure the required app has access to the microphone. You can find and change permissions under Settings -> Apps -> App name -> Permissions.

Troubleshooting Audio Problems on Android

Check Volume Levels: Ensure the media volume is turned up.
Restart Your Device: A simple restart can often resolve audio glitches.
Check Bluetooth Connection: If using Bluetooth, make sure the device is properly paired and connected.
Clear App Cache: Sometimes corrupted app data can cause audio issues. Go to Settings > Apps, select the problematic app, and tap “Clear Cache“.
Check Audio Settings: Open the Settings app and search for “Audio” or “Sound” to explore various audio settings.
