If audio stops after you change a Windows sound setting, first check whether all system audio is silent or only one app is silent. Then verify the selected output, mute and volume levels, connections, and device status before changing drivers. A settings change does not by itself prove that a driver has failed; several different issues can produce the same symptom.
Is all system audio silent, or is only one app affected?
Start by testing a Windows system sound as well as the app where you noticed the problem. This separates a system-wide playback issue from an app-specific one and helps you avoid changing settings that are already working. Microsoft’s general Windows audio guide covers output, device, enhancement, troubleshooting, and driver checks; its app-audio guide focuses on the case where system sounds still play.
| What you observe | Start with | What it suggests |
|---|---|---|
| No sound from system sounds or any app | Selected output, system volume, connection, and whether the device is enabled | Windows may be sending sound to a different output, or the output may be muted, disconnected, disabled, or affected by another audio issue. |
| System sounds play, but one app is silent | That app’s Volume mixer level and selected output | The app can have its own volume or playback destination rather than following the system’s default. |
| The intended speakers or headphones do not appear under Output | Device detection in Device Manager | Windows may not be detecting or loading the audio device correctly; this is the point to investigate the device and its driver. |
After each adjustment, test playback again and stop if sound returns. The checks below are a practical order, not a requirement to perform every step on every PC.
Also note when the failure began. A problem immediately after a Windows update belongs on a different branch from one that appeared after selecting a different speaker, enabling an enhancement, or changing an app’s output. The timing helps choose the next check, but it does not prove what caused the failure.

How do I choose the correct output and check volume?
Windows can send sound to an output other than the one you are listening to. Re-select the intended speakers or headphones in Settings > System > Sound, then confirm the volume is not muted.
- Open Settings > System > Sound.
- Under Output, choose the speakers, headphones, or other playback device you intend to use.
- Check the volume control and mute state for that output, then play audio to test it.
If more than one playback device is connected, check the selection rather than assuming Windows switched automatically. A monitor connected by HDMI, a USB headset, a docking station, Bluetooth equipment, and the computer’s built-in speakers can all appear as separate destinations. The display may be selected even when you are listening through the laptop speakers, or a disconnected dock may remain the selected destination.
USB and HDMI devices can also be playback outputs; Microsoft notes that a connected USB or HDMI device may need to be selected as the default playback device. See Microsoft’s no-sound guidance for speakers and headphones. After selecting a destination, play a known-good sound and watch whether the volume indicator responds. If the indicator moves but you hear nothing, continue with connection, enablement, and enhancement checks rather than repeatedly raising the volume.

Pick the symptom - the matching free tool is one click away.
What should I check if only one app has no sound?
When system sounds work but a particular app does not, check its individual level and output in Volume mixer before changing the system-wide output or reinstalling a driver. App-specific audio settings can differ from the Windows default.
- Open Settings > System > Sound and open Volume mixer. The exact presentation can vary by Windows version.
- Find the affected app and check that its volume is not muted or turned down.
- Check the app’s output-device selection, if shown, and choose the intended playback device.
- Play audio from the app again. If it remains silent, continue to the built-in troubleshooter and, if needed, the audio-services check below.
An app may have been opened while a different output was active and retained that route. Correcting the system default does not necessarily correct the app’s own selection, so inspect both places. Close and reopen the app after changing its mixer route if it does not immediately react. If every other app and Windows system sound still plays, keep the investigation focused on this app’s mixer entry, output choice, and audio services.
Microsoft’s app-specific guidance identifies per-app volume, output selection, audio services, and drivers as possible areas to check. A silent app alone does not show that the speakers or headphones have failed.
Could a connection or disabled device be the problem?
Confirm that the output is physically connected and that Windows has not disabled it. A connected device may still be unavailable for playback if it is disabled in sound settings or device properties.

- PLUG IN AND HEAR SOUND IN SECONDS - USB Type-A connector with a 3.5mm stereo headphone output and a separate 3.5mm mono microphone input. No drivers, no software, no external power - the adapter is USB bus-powered and is recognized as a standard USB audio device.
- WORKS ON WINDOWS, MAC AND LINUX - Driverless on Windows 98SE/ME/2000/XP/Server 2003/Vista/7/8, Linux and Mac OSX, and compliant with the USB Audio Device Class 1.0 specification, so any system that supports class-compliant USB audio will see it. Select it as the sound output and input device after plugging it in.
- TWO JACKS, TWO JOBS - The green jack is stereo OUT for headphones or powered speakers; the pink jack is mono microphone IN for a 3.5mm mic. It does NOT support 4-pole headsets on a single combo plug, it does NOT power passive speakers, and it does NOT add surround sound - it is a stereo 2-channel adapter.
- FOR LAPTOPS AND DESKTOPS THAT NEED AN AUDIO PORT BACK - Adds a headphone and mic port to a laptop, desktop, or mini PC whose onboard jack has failed or was never there. Managed and work-issued computers can block new USB audio devices by policy - check with your IT department before ordering for a company machine.
- SABRENT SUPPORT AND WARRANTY - What is in the box: one USB audio sound adapter. Backed by a 1-year limited warranty, extended to 2 years when you register within 90 days on the manufacturer's website.
- Check that the headphones or speakers are connected to the intended port or connection and powered on if they require power.
- For USB or HDMI equipment, reseat the cable and confirm the monitor, dock, or headset is powered and still connected.
- Return to Settings > System > Sound and inspect the available output devices.
- If the output appears, open its device properties and check whether it is disabled; enable it if necessary.
- Select it as the output and test sound again.
Do not buy replacement hardware as the first response to a settings-related sound problem. First establish whether Windows can see and select the device. If an output disappears when a dock or monitor is disconnected, that is expected; select the built-in or directly connected output instead of treating the disappearance as a driver failure.
Should I turn off audio enhancements?
Yes, as a temporary test: Microsoft identifies audio enhancements as a possible source of sound problems. Disable enhancements for the selected output, test playback, and turn them back on if they were not the cause and you want to use them.
Open the selected output’s sound properties from Settings > System > Sound and locate its audio-enhancement control. The label and location can differ between Windows versions and device drivers. Turn enhancements off for that output, then test the same sound or app that failed. If there is no enhancement control, skip this check rather than changing unrelated options.
Make the change only for the output you are testing. Enhancements are associated with a device, so disabling them for built-in speakers does not necessarily change a USB headset or HDMI display. If sound returns, you have a useful diagnostic result: leave enhancements off while you confirm stable playback, then re-enable them one at a time if you need a particular effect.
How do I run Windows’ built-in audio troubleshooter?
Use the troubleshooter before moving on to driver recovery. For Windows 11, Microsoft recommends starting with the automated audio troubleshooter in Get Help; other available troubleshooting options depend on the Windows version.
- On Windows 11, open Get Help and start its audio troubleshooter. Follow the questions and apply a suggested fix only if it matches the problem.
- If your Windows version offers an audio troubleshooter through Settings, open the available troubleshooting option and follow its prompts.
- When it finishes, test playback through the output and app that were silent.
Keep the intended output connected while the tool runs so it can inspect the device you actually want to use. If it asks you to choose among outputs, select the one that was silent. The troubleshooter may identify a setting or device issue, but its result is not proof that a recent settings change caused a driver failure. If it does not restore sound, use the branch that matches what you see in Sound settings.
What if speakers or headphones don’t appear under Output?
If the intended output is missing, investigate whether Windows detects the device before changing more playback settings. Microsoft’s guidance for a missing or undetected output recommends checking Device Manager, enabling a disabled device, and using the latest driver from the PC or audio-device maker.

- Right-click Start and open Device Manager.
- Expand Sound, video and game controllers and look for the audio device.
- If it is not listed, use Device Manager’s option to show hidden devices, then scan for hardware changes.
- If the device is listed but disabled, enable it.
- If Windows still does not provide the intended output, install the latest audio driver available from the maker of the PC or audio device, then restart the computer and check Sound settings again.
The name shown in Device Manager may not match the everyday name of the speakers or headphones. A laptop’s internal audio may appear under a component or controller name, while a display or USB headset may have its own entry. If a hidden entry reappears after scanning, check whether it can be enabled and selected in Sound settings.

Restart after installing it, then return to Settings > System > Sound and select the output again. If the device remains absent or the manufacturer’s driver does not resolve the issue, the relevant question is whether Windows is detecting the hardware—not whether the volume slider is high enough. See Microsoft’s missing-output-device troubleshooting steps.
When should I update or roll back the audio driver?
Move to driver recovery if the output is still unavailable or silent after the reversible checks and troubleshooter. If audio stopped after a Windows update, Microsoft recommends trying Roll Back Driver when Windows offers it; that option is available only when a previous driver version exists.
- After a Windows update: In Device Manager, open the audio device’s properties and check the driver options. Use Roll Back Driver only if the option is available and the timing fits an update-related failure.
- For a missing, outdated, or improperly loading device: Check for an appropriate driver from the PC or audio-device maker. Microsoft’s general audio guidance also recommends considering driver updates when earlier checks do not fix playback.
- After installing or rolling back a driver: Restart Windows, select the intended output again, and test sound.
Driver rollback is specifically relevant when the problem began after a Windows update; it is not a general first step for every issue noticed after changing a sound setting. Microsoft’s update-related audio article also lists restarting audio services as a troubleshooting option.
Do not interpret the absence of a rollback button as an error. Windows shows that option only when an earlier driver version is available. In a settings-only incident, return first to output selection, mute state, app routing, and device enablement rather than forcing a driver replacement.

Use this check if sound remains broken after the simpler output and app-routing checks, particularly when only an app is affected or audio services may not have started correctly. The relevant services are Windows Audio and Windows Audio Endpoint Builder.
- Open the Windows Services management screen and locate Windows Audio.
- Restart the service if the restart action is available.
- Locate and restart Windows Audio Endpoint Builder as well, if needed.
- Test the affected app or system playback again.
Restarting a service is a temporary diagnostic action, not a substitute for selecting the correct output. After the restart, check the Volume mixer again if only one app was affected, because its per-app route can still be wrong. If these services are unavailable or restarting them does not help, do not treat that alone as a diagnosis. Return to whether the output is visible in Sound settings and Device Manager, and use the corresponding device or driver path.

What if the problem started after a settings change, not Windows Update?
Keep the diagnosis focused on the current symptom rather than assuming the change broke a driver. A wrong output selection, mute state, disabled device, enhancement, or app-specific volume or routing can all explain lost sound; test those before driver changes.
Write down the setting you changed and, if possible, return only that setting to its prior state. Avoid changing several unrelated options at once: if audio returns, you will otherwise not know which adjustment fixed it. Test after every change and stop when playback is restored.

If the issue followed a Windows update instead, use the update-specific driver path above, including rollback only when Windows provides it. The timing matters: Microsoft’s update guidance addresses failures after Windows updates and should not be generalized to ordinary sound-setting changes.
Independent reader supportYour contribution helps us test, update, and keep practical guides available for everyone.Do I need to buy a USB audio adapter?
Usually not. The ordinary fixes for a changed sound setting—selecting the output, correcting Volume mixer routing, enabling the device, disabling enhancements, using the troubleshooter, restarting services, and addressing the driver—do not require a purchase.
A USB audio device can be a conditional fallback if the built-in output is unavailable or appears faulty. Microsoft notes that USB devices can be selected as the default playback device. An adapter does not repair the original Windows routing or driver configuration, however, and it may introduce another output that must be selected in Sound settings. Verify compatibility with the PC and operating system before buying any particular device.
Windows 10 support status
Microsoft states that Windows 10 support ended on October 14, 2025. The troubleshooting guidance above covers Windows 10 and Windows 11, but the end-of-support date is a support-status note, not an explanation for an audio failure. Menu names and the location of the troubleshooter can differ between versions.

Frequently Asked Questions
Could changing a sound setting automatically break my audio driver?
No single cause is established just by the timing. A changed output selection or app-level route can make a working device seem silent, so the symptom and device detection are more useful clues than the fact that a setting was changed.

How can I tell whether the problem is system-wide?
Play a Windows system sound and test a second app. If both are silent, begin with the selected output, mute state, connection, and device enablement. If system sounds work but one app is silent, inspect that app in Volume mixer.
Why does my monitor or USB headset appear but produce no sound?
It may be selected as an output that you are not listening through, or the app may have its own output route. Select the intended device under Settings > System > Sound, check its volume and mute state, and inspect the affected app’s Volume mixer entry.
What does it mean if speakers or headphones don’t appear under Output?
Investigate detection rather than volume. In Device Manager, check Sound, video and game controllers, show hidden devices, scan for hardware changes, enable a disabled entry, and install the latest driver from the PC or audio-device maker if necessary.
When is Roll Back Driver useful?
Use it when the failure began after a Windows update and Windows offers the Roll Back Driver option. The option exists only when a previous driver version is available, and it is not a general first step after an ordinary sound-setting change.
Does Windows 10 still receive support for audio problems?
Microsoft states that Windows 10 support ended on October 14, 2025. The troubleshooting guidance cited here covers Windows 10 and Windows 11, but that end-of-support date is a support-status note, not an explanation for an audio failure.
Can a USB audio adapter fix sound that stopped after a settings change?
A USB audio device can serve as an alternate playback output if Windows detects it and you select it. It does not, by itself, correct the original device’s routing or driver settings, so it is not the general first fix.
The Bottom Line
Separate system-wide silence from one-app silence, then check the selected output, volume, mute state, connections, app routing, and device enablement. Disable enhancements and run the Windows troubleshooter before investigating Device Manager, drivers, or audio services. Roll back a driver only when the problem follows a Windows update and Windows provides that option.
