Laptop speakers fail when output, software, or hardware misroutes sound—check the device, volumes, drivers, and the headphone jack first.
Your laptop can play sound through many paths: built-in speakers, a display over HDMI, a Bluetooth headset, or a USB dock. When sound goes missing, it’s usually routed to the wrong place, muted by an app, blocked by a setting, or held up by a flaky driver. The good news: most no-sound cases take minutes to sort out. Work through the quick checks below, then move to the step-by-step fixes for Windows and Mac.
Fast Triage: Symptoms, Where To Look, What It Means
| Symptom | Where To Look | Likely Cause |
|---|---|---|
| No sound anywhere | System sound output menu | Wrong output device or muted system volume |
| Only some apps are silent | Per-app volume mixer or app settings | App volume set low or muted |
| Sound worked on headphones, not speakers | Audio jack and Bluetooth | Jack stuck in “plugged-in” state or wireless still connected |
| Speakers crackle or fade | Enhancements, spatial sound, EQ | Audio effects or driver glitch |
| Output keeps switching | Bluetooth, HDMI/USB-C display | Auto-switch to the newest device |
| Sound bar shows movement, but nothing you hear | Default output and cables | Audio going to a screen or dock |
| Only left or right plays | Balance in sound settings | Balance slider shifted or speaker damage |
Quick Checks That Save Time
Confirm The Right Output
Pick the device that should play audio. On Windows, open Settings > System > Sound and choose the built-in speakers under Output. Microsoft’s official guide shows the exact screens. On a Mac, go to Apple menu > System Settings > Sound > Output and select Internal Speakers; the steps are on this Apple page.
Turn Up The Right Volumes
Use the keyboard volume buttons, the system slider, and each app’s control. Check the app first—video sites and music players keep their own volume. In Windows, open the Volume mixer to spot a muted app. On a Mac, look for an app-level slider and the Output volume in Sound settings.
Unhook Bluetooth And Displays
Toggle Bluetooth off for a minute, and unplug HDMI or USB-C displays and docks. Many laptops send audio to the newest device they see. If speakers spring back to life when a cable leaves, you found it.
Test A Known-Good Sound
Play a local audio file or a test tone from system settings. If one app stays quiet while others play, the problem sits in that app.
Why My Laptop Speakers Aren’t Working: Common Causes
The Headphone Jack Thinks Something Is Plugged In
The tiny switch that detects a plug can stick. Gently insert and remove a 3.5 mm plug a few times. Power down, then use short bursts of compressed air. If the port is damaged, the system may always think headphones are connected, sending audio away from the speakers.
A Call App Took The Output
Meeting tools can claim a different speaker than the system default. Open their audio menu and set Speakers to your laptop’s internal device. Close the app and test again after you return the setting.
Audio Effects Are Interfering
Windows can add enhancements, surround modes, or spatial sound. If output sounds bad—or disappears—turn those off in the device’s properties, then re-test. Keep EQ apps closed while you troubleshoot.
Drivers Need A Reset
Audio drivers can misbehave after updates or sleep. Reinstalling the device clears that up. In Windows, use Device Manager to remove the audio device, then restart so Windows reloads a fresh driver. If a vendor utility manages audio, update there too.
Audio Services Stalled
On Windows, the Windows Audio services can hang. Restarting them brings sound back without a full reboot. On a Mac, a simple restart refreshes the sound path as well.
Step-By-Step Fixes For Windows
Set The Default Output
Go to Settings > System > Sound. Under Output, pick Speakers (the internal device). If you see a display, dock, or headset listed, switch away from it. While you’re there, click the device and run a test.
Run The Audio Troubleshooter
Open the Get Help app and search for “audio troubleshooter.” It runs tests, flips stuck settings, and can apply fixes in one go. If you installed vendor software, use its diagnostics as well.
Disable Enhancements And Spatial Sound
Open your speaker device’s properties and turn off sound effects, loudness equalization, and spatial modes. Test again. These settings can help later, but they can also mute or distort on some drivers.
Reinstall The Audio Driver
Open Device Manager, expand Sound, video and game controllers, right-click your audio device, and choose Uninstall device (keep the driver removal box checked if present). Restart the laptop. Windows will reinstall a clean driver. If your maker supplies a newer driver, install it over the top.
Restart Audio Services
Press Win+R, type services.msc, and press Enter. Restart these in order: Windows Audio Endpoint Builder, then Windows Audio. If either is stopped, start it and set Startup type to Automatic.
When Sound Still Won’t Play On Windows
Boot once with all USB devices unplugged, Wi-Fi and Bluetooth off, and no external screens. If speakers work in that state but not with your usual setup, reconnect one item at a time until the culprit shows up. If speakers never work—even from a Linux live USB—hardware is the likely cause.
Step-By-Step Fixes For Mac
Pick Internal Speakers And Unmute
Go to Apple menu > System Settings > Sound. On the Output tab, select Internal Speakers, raise the Output volume, and clear the Mute box. The linked Apple page walks through each step.
Reset Routes And Clear Wireless
Turn Bluetooth off for a minute, back on. Disconnect any display or dock. Many Macs hand off audio to the last connected device. If sound returns after you detach gear, set the speaker you want and reconnect only what you need.
Clean The Jack And Reboot
Tap a 3.5 mm plug in and out a few times, then power the Mac down and start it fresh. Dust or a bent contact can make the system think headphones are present.
Update macOS And Test From A New User
Install pending updates, then create a temporary user account and test there. If sound works in the new account, a login item or preference under your main account is stepping on audio.
Deeper Hardware Checks You Can Do
Listen For A Test Tone At All Levels
Play a constant tone and sweep the volume. If the sound cuts out at certain levels, that points to the amplifier or a driver mismatch. If it crackles only during heavy CPU or GPU load, a USB device or power issue may be injecting noise.
Inspect Grilles And Ports
Shine a light into the speaker grilles. Packed lint can muffle or block output. Check for dents along the palm rest and around ports. Liquid marks, salt, or stickiness near the grille often track back to spills.
Know When Service Makes Sense
If the test tone never plays from the internal speakers, even after a clean OS reinstall, or if you hear rattling at all volumes, book a repair. A failed amplifier, torn cone, or damaged jack needs parts.
Fix Paths For Common Scenarios
| Scenario | What To Try | What It Proves |
|---|---|---|
| Audio plays on TV, not laptop | Unplug HDMI/USB-C; set built-in speakers; replug | Auto-switch to display was active |
| Mute light off, still no sound | Check per-app mixer; run troubleshooter; reinstall driver | Software routing issue or driver cache |
| Headphones work, speakers don’t | Clean jack; power cycle; pick internal speakers again | Jack detection stuck or routing wrong |
| Only browser tabs are silent | Unmute tab/site; raise player slider; restart browser | Site-level mute or tab control |
| Crackle after sleep | Disable enhancements; reinstall driver | Effect or driver edge case |
| Drops during calls | Set call app’s speaker to internal; turn off “auto switch” | App-level device choice |
Small Expert Tweaks That Help
Windows: Reset App Volumes
In Settings > System > Sound > Volume mixer, reset volumes and device preferences. This clears odd mutes stuck to one app after a crash.
Windows: Exclusive Mode And Format
Open the speaker properties, format settings tab. Clear “Allow applications to take exclusive control,” then try a standard format like 24-bit, 48000 Hz. Some drivers choke on exotic formats set by pro apps.
Mac: Force Core Audio To Restart
Open Activity Monitor, search for coreaudiod, select it, and press the quit button. The service relaunches and restores sound paths without a reboot.
Mac And Windows: Safe Mode Sanity Test
Start once in safe mode. If speakers work there, third-party extensions or audio effects are involved. Keep only the ones you need.
Keep Sound Solid After You Fix It
Set Defaults And Leave Extras Off
Keep built-in speakers as the default device. Only enable spatial modes or EQ once you confirm stable playback.
Mind App Controls
Streaming sites, music players, and meeting tools stash their own speakers menu and volume. Pick the same device you set at the system level and leave those sliders near the middle to avoid sudden changes.
Update On Your Schedule
Install platform updates and vendor audio drivers after a full backup. If a bad update lands, roll back the driver or restore the last snapshot and wait for the fixed release.
Treat Ports Kindly
Don’t force plugs. Keep lint out with gentle cleaning, and avoid moisture near the keyboard and grilles. Care keeps the detection switch and the speakers happy.
Keep a short test clip on your desktop and play it after each change; feedback makes it easy to spot the step that fixed your speakers.
