The speakers on the laptop do not work: how to fix it yourself

Did the sound on your laptop suddenly disappear or gradually deteriorate, and now the speakers are completely silent? Do not rush to take your equipment to a service center. In 70% of cases, the problem can be solved without disassembling the device - just update the drivers, reset the settings or check the physical connections. But if the problem is a hardware malfunction, more in-depth diagnostics will be required.

In this article we will look at all possible reasons non-working speakers - from software glitches to mechanical damage. You will learn how to check the health of speakers without special tools, which drivers are responsible for the sound in Windows 10/11 And macOS, and also when to contact a specialist. For convenience, we have collected step-by-step instructions with screenshots, a driver compatibility table and answers to frequently asked questions.

1. Diagnosis of the problem: why don't the speakers work?

Before you fix it, you need to understand what's wrong. Let's start with something simple: check if the sound is muted by chance. Click on the speaker icon in the lower right corner of the screen (for Windows) or in the menu bar (for Mac). Make sure the volume slider is not at zero and the “Mute” checkbox is unchecked.

If everything is fine with the settings, but there is no sound, the problem may be:

• 🔊 Software failures — damaged drivers, conflicting applications or viruses.
• 🔌 Physical connections — loose speaker cables inside the laptop or damaged contacts.
• 🎛️ BIOS/UEFI settings - the sound card can be disabled at the motherboard level.
• 🔧 Hardware faults — burnt-out speakers, damaged sound chip.

To narrow down your search, do a quick check:

1. Connect headphones or external speakers to your laptop. If there is sound, the problem is in the speakers themselves or their connection.
2. Run a sound test via Control Panel → Hardware and Sound → Sound → Speaker Properties → Check.
3. Try playing the sound in safe mode (for Windows). If it appears, the software is to blame.

2. Check and update sound drivers

The most common reason for no sound is outdated or damaged drivers. Especially relevant after the update Windows or installing new programs. Let's look at how to update drivers manually and automatically.

Method 1: Update via Device Manager

Open Device Manager (keys Win + X → select the appropriate item). Find a section "Sound, video and gaming devices". If there is an exclamation mark next to the name of the sound card, the driver is not working correctly.

Right-click on the device and select "Update driver". The system will offer two options:

• 🔍 Automatic search — Windows will find and install the latest version.
• 💻 Search this computer — if you downloaded the driver from the manufacturer’s website in advance (for example, Realtek, Conexant or Intel).

Method 2: Uninstall and reinstall the driver

If the update doesn't help, try completely remove the current driver:

1. B Device Manager right click on the sound card → "Remove device".
2. Check the box "Uninstall driver programs for this device" (if any).
3. Restart your laptop. The system will automatically install the driver again.

For laptops Lenovo, HP, Dell And Asus It’s better to download drivers from the manufacturer’s official website - they are optimized for a specific model. For example, for Lenovo ThinkPad T480 driver version needed Realtek Audio 6.0.9030.1 or newer.

3. Setting up sound in Windows and macOS

Sometimes speakers don't work due to incorrect operating system settings. Let's figure out where and what to check.

For Windows 10/11

Open Settings → System → Sound. In the section "Exit" Make sure the correct playback device is selected (eg "Speakers (Realtek Audio)"). Click "Device Properties" and check:

• 🔈 Volume — the slider should be above 10%.
• 🎧 Sound format - try changing it to 16 bit, 44100 Hz (CD quality).
• 🔧 Additional properties - in the tab "Improvements" disable all effects (they may conflict with drivers).

For macOS

On MacBook open System Preferences → Sound → Output. Select built-in speakers («Internal Speakers») and move the volume slider. If there is no sound, try:

• 🔄 Reset NVRAM: turn off Mac, then turn on with the keys pressed Option + Command + P + R (hold for 20 seconds).
• 🛠️ Update macOS - some models (for example, MacBook Pro 2018–2020) require the latest software versions for sound to work correctly.

4. Checking physical connections (disassembling the laptop)

If software methods do not help, the problem may lie in loose speaker cables or damaged contacts. We warn you: disassembling the laptop requires care and may void your warranty. If you are not confident in your abilities, it is better to contact the service.

To check you will need:

• ⚒️ Screwdriver (usually Phillips #00 or T5, depending on the model).
• 🧲 Plastic spatula for separating latches.
• 📸 Camera (to photograph the location of parts before disassembling).

Step by step instructions:

1. Turn off the laptop and remove the battery (if it is removable).
2. Unscrew the screws on the bottom cover (their locations can be found in the model manual, for example for HP Pavilion 15 or Acer Aspire 5).
3. Using a plastic spatula, carefully pry the lid off, starting at the corner. Be careful - the latches are fragile!
4. Locate the speakers (usually located on the sides under the keyboard or on the bottom of the case). Check if the cables are tightly connected to the motherboard.

If the cables come loose, reconnect them and secure them with tape. If there is oxidation on the contacts, carefully clean them with an eraser or alcohol.

⚠️ Attention: Do not touch the motherboard without an antistatic wrist strap. Static electricity can damage ICs, especially the sound controller (e.g. Realtek ALC295 or Conexant CX20752).

5. Diagnostics of sound card and microcircuits

If the speakers are working but there is no sound, the problem may be sound card (audio codec) or its power supply. In laptops, the sound controller is usually soldered into the motherboard, so replacing it is a complex and expensive procedure.

How to check:

• 🔍 Visual inspection: Look for swollen capacitors or blackened chips near the audio jack.
• 📊 Multimeter test: check the voltage at the power contacts of the sound card (for this you need the circuit connector of your model).
• 💻 Checking on Linux: Boot from LiveUSB (eg. Ubuntu). If there is sound, the problem is Windows.

Typical sound card problems:

In 90% of cases, the sound card on laptops is faulty Dell Latitude or HP EliteBook associated with overheating of the microcircuit Realtek ALC due to bad thermal paste or dusty cooler. The solution is to clean the cooling system and replace the thermal interface.

6. When should I contact the service center?

Not all breakdowns can be fixed on your own. Contact a specialist if:

• 🔧 You disassembled the laptop, but found no visible damage, and there is still no sound.
• 💥 The speakers make extraneous noise (squeaking, crackling) even when the sound is turned off - this may indicate a breakdown of the capacitors.
• 🔥 Burn marks or swollen elements are visible on the motherboard.
• 📉 The laptop stopped seeing the sound card even after reinstalling the system.

The cost of repairs in the service depends on the problem:

• Replacing speakers - 800–2000 rubles (including spare parts).
• Sound card repair (chip resoldering) — 2500–5000 rubles.
• Replacing the motherboard - from 5000 rubles (relevant for older models, where the sound controller is inseparable from the board).

⚠️ Attention: At service centers Apple sound repair MacBook (for example, models A1990 or A2159) is more expensive due to proprietary parts. Sometimes it is cheaper to buy external speakers than to repair built-in ones.

7. Alternative solutions: if the speakers cannot be repaired

If repairs are too expensive or impossible, consider alternatives:

• 🎧 Bluetooth speakers or headphones - modern models (for example, JBL Go 3 or Sony WH-1000XM5) produce better sound than built-in speakers.
• 🔌 USB or Type-C sound cards — external DACs (for example, Creative Sound Blaster X3) bypass a faulty audio codec.
• 💻 HDMI audio - if you connect your laptop to a TV or monitor with speakers via HDMI, the sound will go through them.

For owners MacBook with non-working speakers there is another life hack: use Voice Recorder mode in the application Voice memos. Sometimes the sound through the microphone input works even if the speakers are faulty.
