Sound Not Working In HP Laptop
HP laptops frequently lose sound due to driver conflicts, muted playback channels, or physical headphone jack issues. Troubleshoot and fix your HP audio using this step-by-step diagnostic guide.
Symptoms
- Red X icon or mute indicator over the taskbar speaker icon
- Audio plays through headphones but internal laptop speakers remain silent
- Static, crackling, or heavily distorted audio playback from speakers
- HP Audio Control or Bang & Olufsen app fails to launch or detect devices
- Windows system error stating No Audio Output Device is installed
- Sound cuts out randomly after waking the laptop from sleep mode
- Windows volume bar shows sound bouncing, but no real audio comes out
Quick troubleshooting
Step 1
Verify Playback Device and Physical Mute
Click the taskbar volume icon to confirm output is not muted and volume is above zero. Click the output selector arrow to ensure Speakers (Realtek High Definition Audio) is selected instead of an HDMI monitor or Bluetooth device. Unplug all external audio accessories and adapters to isolate the built-in laptop hardware.
Step 2
Restart Windows Audio Services
Press Win + R, type services.msc, and press Enter to launch the background service console. Scroll down to locate Windows Audio and Windows Audio Endpoint Builder. Right-click each service, click Restart, and ensure their Startup Type is set to Automatic.
Step 3
Reinstall Realtek Audio Drivers via Device Manager
Right-click the Start button and select Device Manager, then expand Sound, video and game controllers. Right-click your Realtek or audio device, select Uninstall device, and check the option to attempt driver deletion if available. Restart your HP laptop so Windows automatically re-detects and installs the default audio driver.
Step 4
Reset HP Audio Control Application Settings
Search for HP Audio Control or Bang & Olufsen Audio Control in the Start menu. Right-click the app icon, choose App settings, and click the Repair and Reset buttons. This clears user profile conflicts and restores factory sound mapping for your specific HP chassis.
Step 5
Run HP PC Hardware Diagnostics UEFI
Shut down your laptop completely, press the Power button, and immediately tap F2 repeatedly until the diagnostics menu opens. Select Component Tests, then Audio, and run the main speaker test. If you do not hear the test chimes during this hardware test, your internal speakers or audio chipset require physical repair.
Likely causes
- Corrupted or overwritten Realtek High Definition Audio drivers
- Audio output routed to an incorrect device like an external HDMI monitor
- Windows Audio service (Audiosrv) stopped or disabled
- Software conflicts within HP Audio Control or Bang & Olufsen App
- Stuck micro-switch inside the 3.5mm audio headphone jack
- Disconnected or damaged internal speaker wiring harness
- Hardware failure of the audio codec chip on the motherboard
What's going on
Losing sound on an HP laptop can turn video calls, streaming, and daily productivity into a frustrating experience. Audio failure on HP Envy, Pavilion, Spectre, and OMEN laptops usually stems from software layer conflicts—specifically between Windows Updates, Realtek drivers, and OEM audio software like Bang & Olufsen or DTS Audio Control. However, if sound vanishes completely at a system boot level, hardware damage to the motherboard's audio codec chip or speaker modules could be the culprit.
Symptoms people notice
- Red 'X' or error symbol on the Windows system tray speaker icon.
- Windows sound slider shows active equalizer bouncing, but the internal speakers remain completely silent.
- Audio works through 3.5mm headphones or Bluetooth headsets, but disconnects from internal speakers.
- High-pitched static, popping noises, or robotic distortion when playing media.
- HP Audio Center / Bang & Olufsen Control Panel displays "Audio Service Not Running" or fails to open.
- Error notification stating "No Audio Output Device is installed".
Likely causes
- Corrupted or Incompatible Audio Drivers: Windows Update frequently overwrites HP-customized Realtek drivers with generic versions, breaking equalizer routes and Bang & Olufsen integration.
- Incorrect Default Playback Target: Audio is mistakenly routed to a phantom HDMI port, virtual audio cable, or paired Bluetooth headset.
- Windows Audio Service Failures: Background dependencies (
AudiosrvorAudioEndpointBuilder) stopped running after a system crash or sleep transition. - Stuck Headphone Jack Detection: The micro-switch inside the 3.5mm jack is mechanically jammed, causing the laptop to permanently think headphones are plugged in.
- Damaged Internal Speakers or Wiring: Physical impact, liquid contact, or overdriven speaker cones can cause voice coil burnouts or loose motherboard connections.
Quick checks first
Before pulling out screwdrivers, start with basic software resets. Click the sound icon on the taskbar and verify that "Speakers (Realtek High Definition Audio)" is set as the active output device. Unplug all USB hubs, HDMI cables, and Bluetooth transmitters to ensure audio isn't being redirected off-board. Next, run the native Windows Audio Troubleshooter by going to Settings > System > Sound > Troubleshoot.

When it's a real repair
If running the HP Hardware Diagnostics UEFI tool (F2 at startup) fails to produce sound during the component sound test, your issue is physical. Hardware-level audio failures on HP laptops include:
- Jammed or Damaged 3.5mm Audio Port: Requires replacing the auxiliary sub-board or resoldering a new jack onto the I/O board.
- Blown Speaker Modules: Requires disassembling the lower chassis case, unplugging the speaker harness, and installing a new stereo speaker assembly.
- Faulty Audio Codec Chip: A damaged Realtek or Cirrus Logic IC on the main system board requires micro-soldering or a full motherboard replacement.
If you suspect wider motherboard power or controller issues, browse our detailed /problems index to cross-reference board-level symptoms.
DIY vs professional repair
Replacing an HP laptop's internal speakers or headphone jack daughterboard is manageable for DIYers with basic tools like a PH0 Phillips screwdriver, a plastic spudger, and anti-static precautions. Most HP service manuals provide clear routing paths for internal speaker wiring.
However, if the failure involves micro-soldering audio controller chips directly on the system board, professional repair service is recommended. If you feel uncomfortable opening your laptop chassis, you can consult /reviews to read about mail-in repair options or connect with an LML Experts technician for direct repair support.
Next steps
Start by completing the software steps in our troubleshooting guide above—most HP audio problems resolve after reinstalling the clean HP-provided Realtek driver package. If software troubleshooting fails, open your laptop's lower case to inspect internal speaker cables for loose connections or pinched wires.
