No sound from your speakers? Here's the fix
No audio can mean the wrong output device is selected, the volume is muted somewhere you're not looking, or a driver or cable issue. Work through these steps in order before assuming your speakers are broken.

Before you start troubleshooting, run the actual test so you know what's broken.
Run the Speaker TestQuick checks first
- Check the physical volume knob or buttons on the speakers themselves, and confirm they're powered on.
- Check the system volume isn't muted, click the speaker icon and make sure the slider isn't at zero.
- Run our Speaker Test to play left, right and stereo tones and confirm both channels actually work.
- Check the app you're using has its own separate volume or mute control, video players and browsers often have one.
- Try headphones in the same port. If they work, the issue is the speakers or the connection to them, not the computer.
Check the correct output device is selected
Windows 11
- Right-click the speaker icon in the taskbar and choose "Sound settings" or "Sound mixer".
- Under Output, confirm the correct device (speakers, headphones, monitor, or HDMI display) is selected.
- If you recently connected a monitor or TV over HDMI, Windows may have quietly switched output to it.
- Open Volume mixer and check the specific app isn't muted individually.
macOS
- Open System Settings > Sound > Output.
- Select the correct output device from the list.
- Hold Option and click the volume icon in the menu bar for a quick way to switch outputs.
Chromebook
- Click the status area in the bottom right and check the volume slider.
- Click the arrow next to it to pick the correct output device if more than one is listed.
iPhone
- Check the physical mute switch on the side of the phone.
- Swipe down for Control Center and check the volume level and any AirPlay device selected.
- Confirm you're not still routed to a Bluetooth speaker or headphones that are out of range or off.
Android
- Press the volume button and tap the settings icon that appears to check the media volume specifically, not just ringtone volume.
- Open Settings > Sound & vibration > check any connected Bluetooth device isn't intercepting audio.
Fix Bluetooth speaker and headphone issues
- Forget the device and re-pair it, this clears a large share of Bluetooth audio glitches.
- Move closer to the computer or phone, Bluetooth range and interference from other 2.4GHz devices can cause dropouts.
- Charge the speaker or headphones fully, low battery causes some Bluetooth devices to mute or disconnect audio while staying connected.
- Check only one device is trying to connect at once, most Bluetooth speakers only handle one active audio stream.
Update or reset the audio driver (Windows)
- Right-click the Start button and open Device Manager.
- Expand "Sound, video and game controllers".
- Right-click your audio device and choose "Update driver", then "Search automatically".
- If that doesn't help, right-click and choose "Uninstall device", then restart, Windows reinstalls the driver on boot.
- Also check Settings > System > Sound > Troubleshoot common sound problems, Windows' built-in tool catches several config issues automatically.
Check cables and ports
- Make sure a 3.5mm cable is pushed in fully, a slightly loose jack often only outputs one channel or nothing at all.
- Try a different port if you have more than one audio jack, some computers have separate front and rear ports wired differently.
- For HDMI or DisplayPort audio, check that the display or receiver is set as the correct audio output, not just the video output.
- Try the speakers on another device to rule them out entirely.
When it's a hardware fault
If sound works through headphones but never through the built-in speakers, and no driver or settings fix changes that, the internal speaker or its amplifier may have failed. Signs it's genuinely hardware:
- Sound works fine right after a fresh operating system install or on another user account, but fails again after driver updates, this points to software, not hardware.
- One channel is silent no matter what device or app you use, this usually means a blown speaker or a damaged cable, not a setting.
- External speakers powered from a wall outlet make no sound and show no power light, check the power cable and outlet before assuming the speaker itself failed.
How audio output actually gets routed
Modern computers rarely have one audio output, they have five or six. Internal speakers, a headphone jack, a USB headset, an HDMI or DisplayPort connection to a monitor, a Bluetooth speaker and sometimes a virtual device installed by conferencing or recording software all appear as separate outputs. The operating system picks one, apps can override that choice individually, and connecting a new device silently reshuffles the priority order.
This is why sound so often disappears the moment you plug in a monitor or dock. The display announces that it supports audio, the system dutifully switches output to it, and the monitor either has no speakers or has them turned down. Nothing is broken, the sound is simply going somewhere you cannot hear it. Checking the output device list before anything else resolves a large share of no-sound reports.
Per-app volume, the setting people forget
Both Windows and macOS allow individual applications to have their own volume level, and browsers add a third layer by allowing per-tab muting. A single accidental click can mute one app permanently while everything else plays fine, which makes the problem look far stranger than it is.
- On Windows, open the Volume mixer from the sound settings and check every slider, not just the master.
- In any browser, look for a small speaker icon on the tab itself, right click the tab and choose unmute site if present.
- Video players, games and conferencing apps almost always have an internal volume control separate from the system one.
- Streaming sites often remember a muted state per site, so muting one video mutes them all on that domain.
Isolating hardware from software in three tests
Before opening driver settings, three quick comparisons will tell you whether the fault is physical.
- Play sound through headphones in the same port. Working headphones mean the port, driver and system audio are all fine and the speakers or their connection are at fault.
- Play sound from a different application. If one app is silent and another is not, it is a software setting, never a speaker fault.
- Play sound from a different device entirely, a phone connected to the same speakers. Silence there points squarely at the speakers or cable.
Our speaker test is useful here because it plays left, right and stereo tones separately. A channel that is silent in isolation but sounds present in a stereo mix is a classic sign of a partially inserted 3.5mm jack or a damaged cable, and it is very easy to miss when listening to music.
Keeping audio reliable long term
A few small habits prevent most repeat failures. Set your preferred output device explicitly rather than relying on automatic switching, and check it again after connecting a dock or monitor. Keep Bluetooth speakers charged, since low battery causes some models to stay connected while producing no sound at all. Unplug and inspect 3.5mm cables occasionally, the connector near the plug is the most common failure point on any audio cable.
- Avoid installing multiple audio enhancement utilities, they conflict and produce silence or distortion.
- Note the driver version that works before updating, so a rollback is straightforward if the new one misbehaves.
- Test both channels after any hardware change rather than assuming stereo is intact.
- If you use a dock, connect audio directly to the computer for critical calls, docks are a frequent source of intermittent audio dropouts.
Common questions about missing sound
Why did sound stop after connecting a monitor?
The monitor advertised audio support over HDMI or DisplayPort and the system switched output to it. If the monitor has no speakers, or its volume is down, you hear nothing. Change the output device back to your speakers or headphones, and set it explicitly so the system stops switching automatically.
Why does only one speaker play?
Nearly always a physical connection. A 3.5mm plug that is not fully inserted contacts only one channel, and a cable damaged near the connector does the same. Test with the left, right and stereo tones in our speaker test, then check the balance slider in sound settings before assuming a speaker has failed.
Do I need to reinstall the audio driver?
Only if the device is missing or flagged in Device Manager, or if sound broke immediately after an update. Uninstalling the device and restarting lets Windows reinstall a clean driver automatically, which is safer and quicker than hunting for a download, and it resolves most driver-related silence.
Why is Bluetooth audio delayed?
Wireless audio carries inherent latency from encoding and buffering, typically well over a tenth of a second. That is unnoticeable for music but obvious on video and unusable for games. Video players often compensate automatically, while for gaming or editing a wired connection remains the only reliable answer.
A quick checklist before an important call or presentation
Audio failures are far easier to fix five minutes early than thirty seconds late. This short routine catches almost everything that commonly goes wrong with playback.
- Connect any dock, monitor or headset first, then check which output device the system has selected.
- Play a short clip and confirm you hear both left and right channels, not just one.
- Check the per-application volume for the app you will actually use, not only the master slider.
- If you plan to share a video, confirm the meeting app is set to share computer sound as well as the screen.
- Keep a wired pair of headphones nearby as an instant fallback if a wireless device misbehaves.
Doing this in the same order each time builds a habit that takes under a minute, and it removes the most common cause of a presentation stalling in front of an audience.
