Laptop sound stops when the wrong output, muted mixer, a driver crash, or a Bluetooth handoff silences audio—check device, mixer, and drivers.
Quick Answer And First Checks
Silent laptop? Start with the fastest flips. Verify the speaker icon is not muted, press the volume buttons, and try a second app. Plug in wired headphones, then unplug. Toggle Bluetooth off to rule out a stray headset. Pick the correct output in your system sound menu. If the bar moves but you hear nothing, restart the device and run the built-in audio troubleshooter. Many cases end here.
Use these steps right away:
- Pick the right output device in the Sound menu.
- Open the volume mixer and raise app sliders.
- Turn off Bluetooth and retry local speakers.
- Unplug docks and HDMI, then test again.
- Reboot the laptop to clear stuck audio tasks.
Symptom To Fix Map
| Symptom | Quick Checks | Likely Fix |
|---|---|---|
| No sound anywhere | Mute off, output selected, reboot | Run audio troubleshooter; restart audio driver |
| Only one app is silent | App volume slider, in-app settings | Raise app slider; switch output in the app |
| Headphones work, speakers do not | Unplug and replug; jack sensor | Clean jack; pick “Speakers” as output |
| Sound cuts when a call starts | Bluetooth profile swap | Pick stereo profile; end call; disable “hands-free” |
| HDMI screen has no audio | Check cable, sink device | Select the TV/monitor as output or use laptop speakers |
| Clicks, crackle, or dropouts | CPU spikes, power plan | Close heavy apps; set balanced power; update driver |
Why The Sound On A Laptop Stops Working: Common Triggers
Most loss of audio breaks down into a few buckets: a wrong output route, muted sliders, a Bluetooth handoff, a driver crash, or hardware. The good news: software causes are far more common than speaker failure. Work through the items below in order. Each step helps confirm one cause and clear it.
Wrong Output Device Or App Mute
Systems can point sound at a device you are not using. Pick the main output in Settings, then open the mixer and raise each app slider. Media players and browsers also have their own device pickers. If you use voice chat, check its audio menu as well.
Bluetooth Took Over Output
Nearby earbuds can steal playback. Turn Bluetooth off, or open the output list and pick the laptop speakers. For headsets, pick the “stereo” entry for music and the “hands-free” entry only for calls.
After An Update: Driver Or Permissions Reset
Big updates can swap drivers or reset privacy gates. On Windows, open Settings and run the audio troubleshooter, then reinstall or roll back the audio device in Device Manager. On macOS, quit the “coreaudiod” task or restart the Mac to refresh the sound stack.
No Sound From One App
Browsers can mute tabs, meeting apps can mute themselves, and games can route to a different device. Open the app menu, pick the desired device, and raise its internal slider. If that fails, quit and relaunch the app.
Headphone Jack Sensor Stuck
Some laptops hold the “headphones inserted” state after a pull. Insert and remove the plug a few times. If dust is present, power down and use short bursts of air at an angle. Then test speakers again.
HDMI Or Dock Changed The Route
External screens advertise themselves as audio targets. When you plug one in, the route may flip. Open the output list and pick the device you want. If the display has no speakers, pick the laptop speakers or a soundbar on the screen.
Physical Mute Buttons And Switches
Some keyboards have a mute button or a speaker toggle. Tap it once to unmute. Many business laptops also ship with a mic mute light; that only affects the mic, not speakers.
Step-By-Step Fixes For Windows 10 And 11
Work through these clean, repeatable steps:
- Right-click the speaker icon. Open “Sound settings.” Pick the correct output under “Choose where to play sound.”
- Open “Volume mixer.” Raise Device and App sliders. Make sure the target app is not muted.
- Run “Playing Audio” under Settings > System > Troubleshoot > Other troubleshooters. Let it apply fixes.
- Use the Win+X shortcut, choose Device Manager. Expand “Sound, video and game controllers.” Right-click your device, choose “Update driver.” If the issue started today, choose “Properties > Driver > Roll Back.”
- Restart the Windows Audio service: use Win+R, type
services.msc. Restart “Windows Audio” and “Windows Audio Endpoint Builder.” - If HDMI is connected, set your TV or monitor as the default when you want sound there, or switch back to “Speakers” for the laptop.
- Install pending Windows Updates. Reboot.
Full step lists live in the official guide. See Fix sound problems in Windows.
Step-By-Step Fixes For macOS
Use this path on a MacBook or Mac laptop:
- Go to System Settings > Sound. Under Output, pick “MacBook Speakers” or your preferred device. Move the Output volume slider to the right.
- Open the app that is silent. Check its audio menu or preferences and pick the same output.
- Turn Bluetooth off for a minute, then back on. Re-pick your target device.
- Quit “coreaudiod” in Activity Monitor, or restart the Mac. This refreshes the audio engine.
- If the issue began after new gear or an update, shut down fully, wait ten seconds, then power on. Test again.

Cause To Steps By Platform
| Cause | Windows Steps | Mac Steps |
|---|---|---|
| Wrong output device | Sound settings > pick output | System Settings > Sound > Output |
| App is muted | Open Volume mixer; raise slider | Check app menu; raise slider |
| Bluetooth handoff | Turn off Bluetooth; pick Speakers | Disable Bluetooth; re-select device |
| Driver crash | Restart Audio service; update driver | Quit “coreaudiod” or restart |
| HDMI route | Pick TV/monitor or pick Speakers | Pick display or MacBook Speakers |
| Jack sensor stuck | Replug; clean jack; pick Speakers | Replug; clean jack; pick Speakers |
When It Points To Hardware
After software paths fail, test the chain. Play a local file you trust. Try a USB headset or USB-C dongle. If the USB path works but the built-in speakers stay silent, the amp or cable inside the laptop may be at fault. If every output is silent, the issue may be on the board.
Run the vendor’s built-in diagnostics. Dell, HP, Lenovo, and Apple all ship test tools you can launch at boot or from an app. If a test tone plays there but not in the desktop, the OS path is the suspect. If no test tone plays at all, repair is likely.
Still stuck? Back up files and book a repair visit with the maker or a trusted shop. Bring a short list of actions you tried and the time the issue began. Clear notes speed the visit.
Deeper Checks That Often Get Missed
A few lesser known settings can mute playback even when the main sliders look fine. Work through this set when the basics do not bring sound back.
Disable App Control Mode (Windows)
Some drivers let one app take full control of the device. That setting can leave other apps silent. Right-click the speaker icon, open “Sound settings,” then “More sound settings.” Double-click your output, open the last tab, and clear both boxes that let apps take full control. Click OK and test.
Turn Off Enhancements Or Spatial Sound
Enhancement stacks can glitch. In the same device window, turn off “Enable audio enhancements” and set “Spatial sound” to Off. If playback returns, re-enable features one at a time later.
Match The Sample Rate
When apps and the device use different sample rates, some drivers fail to open. In Windows, set the Default Format to 48,000 Hz, 24-bit and retest; then try 44,100 Hz. On a Mac, open Audio MIDI Setup, select your output, and set the Format to 44,100 Hz or 48,000 Hz. Keep it steady across apps that stream at the same time.
Reset App Permissions And Cache
If a browser tab keeps failing, clear site settings for camera and mic and reload the page. Meeting apps often gain a fresh audio path after a sign out and sign in. On Windows, reinstalling the device from Device Manager also clears stale paths.
Power, Performance, And Interference
Audio needs steady CPU time. If the system is thrashing, sound can skip or drop. Close heavy tabs and video editors. Set a balanced power plan on battery and plug in during long calls. Keep Wi-Fi and Bluetooth radios a short distance from USB 3 hubs to avoid noise on 2.4 GHz headsets.
For USB audio clicks, try a different port or a simple USB-C to audio adapter. Avoid daisy chains through hubs during calls. Short, direct paths tend to be stable.
Prevent Repeat Issues
Small habits keep audio steady. Here are the big wins:
- Set a single default output and turn off auto switch in headset apps.
- Keep one chat app logged in at a time to avoid device grabs.
- Avoid random driver updaters; use Windows Update or the maker’s tool.
- Update meeting apps and browsers. Old builds misroute sound.
- Mind docks and screens. Unplug cleanly before a lid close.
- Reboot after big updates before the next call.
Set a weekly reminder to play a short test tone and check your output list after any dock or display change. That habit catches flips early and saves time when live calls, classes, or streams start too.
