If a Lenovo laptop has no sound, crackles or plays quietly, Microsoft's audio articles give the order that applies to every Windows laptop: run the audio troubleshooter in the Get Help app, check the right output is selected (select the speaker icon on the taskbar and pick the speakers or headphones you want), then update the audio driver and check what changed after a recent Windows update. Lenovo has audio articles for its ThinkPad line and a general one for fixing audio or sound problems in Windows 10 and 11.
Lenovo laptops differ in what can take the sound: a ThinkPad on a USB-C dock, a Legion driving an HDMI TV, or a Yoga paired to Bluetooth headphones will each send it away from the speakers, so unplug and unpair first.
Differential
Likely causes of “Lenovo ThinkPad T14 Gen 5 has no sound or distorted audio”, and how to tell them apart
- 1
Sound is going to another device
What separates it The laptop is silent but a dock, HDMI TV or Bluetooth headset is connected
How to confirm Click the speaker icon in the taskbar, pick the laptop speakers from the list, and unplug whatever else is attached
- 2
A muted or low volume path
What separates it The volume slider shows plenty of volume up but nothing plays from the speakers
How to confirm Check the taskbar volume, the app's own volume and the hardware mute key on the keyboard
- 3
A driver problem after an update
What separates it The sound went silent just after a Windows update, having worked until then
How to confirm Microsoft covers audio lost after an update; refresh the audio driver or revert to the previous one
- 4
A missing or undetected output device
What separates it The Sound settings list no speakers because of a missing or undetected output device
How to confirm Microsoft's missing audio output article covers re-enabling and reinstalling the device
- 5
A hardware fault
What separates it There is no sound from any output after driver reinstall because of a hardware fault
How to confirm Run Lenovo's diagnostics in Vantage or the boot diagnostics; if it fails the speakers or board need service
Before you touch a setting
Record this first — changing settings destroys the evidence
- Which Lenovo laptop you have (ThinkPad T14 or X1 Carbon, IdeaPad Slim 5, Legion Pro 7i or Yoga 9i), its machine type and Windows version
- What is connected to the USB-C, HDMI and headphone ports and whether a headset is paired
- Which output Windows has selected, and whether the sound hardware appears in Device Manager
- Whether the fault is in every app and began after an update

0 of 7 completedRun the audio troubleshooter
ReversibleOpen Get Help, run the audio troubleshooter and follow its suggestions, as Microsoft says to.
Check the output device
ReversibleOpen the speaker icon in the taskbar, expand the list of outputs and tick the built-in speakers; pull out any dock or headset first.
Check mute and volume
ReversibleCheck the keyboard mute key, the taskbar volume and the volume inside the app, since any one of them can silence the sound.
Update the audio driver
ReversibleUpdate the audio driver, by using Lenovo Vantage or Windows Update, or Device Manager, to install the audio driver.
Roll back if it began after an update
ReversibleIf the trouble began with an update, use Roll Back Driver in Device Manager, or System Restore to a date before it.
Restart
ReversibleRestart the laptop and test again before making any other change, because a restart clears many temporary faults.
Run Lenovo diagnostics
ReversibleRun Lenovo diagnostics, by using Lenovo Vantage's hardware scan, or the boot diagnostics, and running the audio test.
Model-specific
What is true of this model and not of its siblings
- Audio and ports by model
- ThinkPad X1 Carbon Gen 13 and T14 Gen 5 are built for USB-C and Thunderbolt docks. IdeaPad Slim 5 usually includes USB-A and HDMI plus USB-C. Legion Pro 7i has HDMI on its discrete NVIDIA GPU. Yoga 9i 2-in-1 has a rotating soundbar hinge.
- Lines
- ThinkPad is Lenovo's business line, IdeaPad the mainstream line, Legion the gaming line and Yoga the convertible line, per Wikipedia's lineup articles.
- Machine type instead of a part number
- You do not need a part number: Lenovo identifies a laptop by machine type and serial number.
- Tools and supplies
- The Lenovo charger and a second known-good cable, a flashlight to look into the ports and vents, a dry towel for the desk and a USB stick if you need recovery media. The laptop should not be opened at home.
- Repair cost
- Most sound faults come down to a driver, a setting or an attached device, so the fix is free. If the speaker hardware fails, an independent shop repair is typically $99 to $299 with a free diagnostic, per BadgerLayer's 2026 laptop repair guide.
Stop boundary
When this stops being a self-service repair
- !If Lenovo's diagnostics fail the audio test, contact Lenovo Support
- !If the headphone port is loose or damaged, book a repair rather than repeating software steps
- !If the laptop shows swelling signs together with the audio fault, stop using it and see the battery page

Common questions
Why is my ThinkPad silent on a dock?+
A dock or HDMI monitor can become the output device. Choose the built-in speakers in the taskbar list or disconnect the dock.
Does the Yoga 9i have special audio?+
It has a rotating soundbar hinge per the catalog. The Windows steps are the same, and tent or tablet mode can change which way the speakers face.
