If your speakers, headphones, or other playback device have disappeared from Windows 11, check the selected output, connections, audio services, and drivers. Follow these steps before reinstalling anything.

1. Check the physical connection

For USB or 3.5 mm devices, reconnect the cable and try another suitable port. For Bluetooth headphones, confirm they are paired and connected. If you use a monitor over HDMI or DisplayPort, remember that it may appear as an audio output only when the display and graphics driver support audio.

2. Open Sound settings

Go to Settings → System → Sound. Under Output, check the available device list and select the intended speakers or headset. Open More sound settings if you need the classic Playback list. Right-click in the list and enable showing disabled devices; if your device appears disabled, enable it.

3. Run the audio troubleshooter

Open Settings → System → Troubleshoot → Other troubleshooters and run the audio troubleshooter if available. Apply a suggested fix only after reviewing what it will change, then test playback.

4. Restart Windows audio services

Search for Services and open it. Find Windows Audio and Windows Audio Endpoint Builder. If they are stopped, start them; if running, use Restart where available. You may need administrator permission.

5. Inspect Device Manager

Right-click Start and choose Device Manager. Expand Sound, video and game controllers and Audio inputs and outputs. Check for warning symbols. Use Scan for hardware changes, then install an appropriate driver from Windows Update or your PC/audio-device manufacturer’s official support page.

6. Roll back a recent driver

If the output disappeared immediately after a driver update, open the device’s Properties in Device Manager and check the Driver tab for Roll Back Driver. Use it only if available and the timing matches the problem.

7. Test another app or device

Try playing audio in another application and, if possible, connect a different headset or speaker. If only one app is affected, select the correct output inside that app. If no device appears after driver checks, consult the computer or audio-device manufacturer.

Bottom line: Verify the connection and output selection first, then check disabled devices, audio services, and model-specific drivers.

If your microphone is very quiet in Windows 11, check its input level, selected device, app permissions, and any headset controls. A low recording level may be caused by Windows settings or by the microphone itself.

1. Select the right microphone

Open Settings → System → Sound. Under Input, select the microphone you actually use. Speak and watch the input meter if available. If the meter reacts to a different device, change the selection.

2. Increase the input volume

Open the selected microphone’s properties and raise the input volume gradually. Test your voice after each adjustment. If the device has a physical gain wheel, mute switch, or inline control, check that too. Avoid setting gain so high that your voice becomes distorted.

3. Check app permissions

Go to Settings → Privacy & security → Microphone. Make sure microphone access is enabled and that the relevant app is allowed to use it. Some desktop programs have their own permission or device-selection controls.

4. Check the app’s audio settings

In the calling, recording, or streaming application, select the same microphone and review its input gain, automatic gain control, noise suppression, and mute settings. Temporarily compare with enhancements disabled if the app provides that option.

5. Inspect the connection

Reconnect the microphone. For a 3.5 mm headset, make sure the plug is in the correct combo jack or use the appropriate adapter. For USB devices, test another port and connect directly rather than through a hub. For Bluetooth, check that Windows selected the headset’s microphone profile.

6. Update or roll back the driver

Use Windows Update or the manufacturer’s official support page for the exact computer or audio device. If the problem began after a driver update, check Device Manager for a supported rollback option. Restart and test again.

7. Compare with another device

Test the microphone in another app or on another computer if possible. If it is quiet everywhere, check the device manual, cable, and physical controls. If it works elsewhere, focus on the original app’s settings and permissions.

Bottom line: Choose the correct input, adjust its volume, verify privacy permissions, and inspect the app’s own controls. Compare across apps or devices before replacing the microphone.

If Windows 11 notifications are not appearing, check notification permissions, Do not disturb, individual app settings, and Windows components.

## Method 1: Turn notifications on
Open Settings > System > Notifications, turn notifications on, select the affected app, and make sure its notifications are enabled.

## Method 2: Check Do not disturb
Review Settings > System > Notifications > Do not disturb. If enabled, Windows can suppress notifications according to its rules.

## Method 3: Check individual app options
Make sure banners, notification-center alerts, and sounds are enabled for the affected application.

## Method 4: Restart Windows Explorer
Press Ctrl + Shift + Esc, find Windows Explorer, right-click it, and select Restart.

## Method 5: Update the affected app
If only one application has stopped notifying you, update it through the Microsoft Store or its official update system.

## Method 6: Repair Windows files
Open Terminal as administrator and run DISM /Online /Cleanup-Image /RestoreHealth, then sfc /scannow. Restart after the scans.

### Final tip
If notifications appear but make no sound, check the notification sound setting and Windows volume separately.

If your Windows 11 PC keeps restarting without warning, the cause may be an automatic restart after a system error, a driver problem, overheating, or a power issue. Work through these checks in order and save important files whenever the computer stays on long enough.

1. Check whether Windows is reporting a stop error

If a blue screen appears briefly, Windows may restart before you can read it. Open Settings → System → About → Advanced system settings. Under Startup and Recovery, choose Settings and temporarily clear Automatically restart. If a stop code appears next time, write it down; it can help identify the failing driver or component. Turn the option back on after troubleshooting if you prefer.

2. Review Reliability Monitor

Search Windows for View reliability history. Look for red critical-event markers around the time of each restart. Open the entries and note whether they mention a Windows failure, hardware error, or a particular application. Repeated identical events are more useful than unrelated warnings.

3. Install appropriate updates

Go to Settings → Windows Update and install available updates, then restart normally. Also check the computer manufacturer’s support page for your exact model for chipset, storage, and graphics drivers. Avoid third-party driver updater utilities.

4. Check temperature and power

Make sure the vents are clear and fans can move air. On a desktop, check that power cables are firmly connected; on a laptop, test with its correct charger. If restarts happen during demanding games or workloads, heat or unstable power may be involved. Stop using the machine if you notice a burning smell, unusual electrical sounds, or a swollen battery.

5. Repair Windows system files

Open Terminal or Command Prompt as administrator and run DISM /Online /Cleanup-Image /RestoreHealth. When it finishes, run sfc /scannow. Restart after both commands complete and note any repair messages.

6. Undo recent changes

If the restarts began after installing hardware, software, or a driver, disconnect newly added peripherals and uninstall or roll back the recent change where appropriate. If Windows cannot stay running, use Windows Recovery Environment and its Startup Settings or System Restore options.

When to seek help

If the computer continues restarting before Windows loads, or hardware errors appear repeatedly, back up accessible data and contact the device manufacturer or a qualified technician.

Bottom line: Capture any stop code, inspect Reliability Monitor, update model-specific drivers, and check heat and power before making major changes.

Crackling, popping, or distorted sound in Windows 11 can come from an audio enhancement, driver mismatch, connection issue, or an application using the device incorrectly. Test one change at a time and check whether the problem affects headphones, speakers, or every audio output.

1. Check the physical connection

For wired headphones or speakers, reconnect the plug and test another port if available. For USB audio devices, connect directly to the PC rather than a hub. For Bluetooth audio, move closer to the computer and temporarily disconnect other Bluetooth devices.

2. Select the correct output

Open Settings → System → Sound and choose the intended output device. Adjust the volume and use the test option if shown. If several outputs are listed, make sure Windows is not sending sound to a monitor or unused device.

3. Turn off audio enhancements

In the selected output device’s properties, look for Audio enhancements and set them to Off for testing. Also temporarily disable spatial sound if it is enabled. These features can sometimes conflict with a driver or audio application.

4. Try another format

Open the device’s advanced sound properties and, if available, test a different default format. Apply the change and listen again. Restore the original format if it makes the sound worse or does not help.

5. Restart audio services and the PC

Save your work and restart Windows. A restart can clear a temporary audio-service problem. If crackling happens only after waking from sleep, note that pattern because it may point toward a driver or power-management issue.

6. Update or roll back the audio driver

Use Windows Update or the official support page for your PC, motherboard, or audio device. If the problem began immediately after a driver update, check Device Manager for a supported Roll Back Driver option. Avoid third-party driver updater utilities.

7. Check applications and CPU load

Test sound in more than one app. If only one program crackles, check its audio settings and updates. Open Task Manager and see whether CPU usage is unusually high during playback; close only unnecessary applications you recognize.

8. Run the audio troubleshooter

Open Settings → System → Troubleshoot → Other troubleshooters and run the audio troubleshooter if it is available in your Windows build. Follow its recommendations and retest.

Bottom line: Verify the output and connection, disable enhancements temporarily, and update the correct driver. If distortion occurs across devices and applications, record when it happens and seek device-specific support.

If your Windows 11 microphone works but your voice is very quiet, check the selected input device, input volume, app settings, permissions, and drivers.

## Method 1: Select the correct microphone
Open Settings > System > Sound. Under Input, select the microphone you actually use and speak to check the input level.

## Method 2: Increase input volume
Open the selected microphone’s properties and raise its input volume. Test again.

## Method 3: Check the application
If the microphone is quiet only in Discord, Teams, a browser, or another app, check that application’s input device and volume.

## Method 4: Check permissions
Go to Settings > Privacy & security > Microphone. Make sure microphone access is enabled and the affected application is permitted to use it.

## Method 5: Update the audio driver
Open Device Manager > Audio inputs and outputs. Update the microphone device or install the current driver from the PC manufacturer’s official support page.

## Method 6: Test another microphone
Connect another microphone or headset. If it has normal volume, investigate the original microphone, cable, USB port, or headset hardware.

### Final tip
If every microphone is quiet, focus on Windows settings and drivers before replacing the headset.
