Check whether Windows can detect and enable the audio device in Device Manager, then install the laptop manufacturer’s audio driver if it remains missing.
1. Check whether the audio device is disabled or hidden
- Select Start, type Device Manager, and open it.
- Expand Sound, video and game controllers.
- If the audio device appears—possibly named Realtek Audio, High Definition Audio, or similar—right-click it:
- Select Enable device if that option is available.
- Otherwise, select Update driver → Search automatically for drivers.
- If no audio device appears:
- Select View → Show hidden devices.
- Select Action → Scan for hardware changes.
- Restart the laptop and check Settings → System → Sound → Output.
These are Microsoft’s recommended first checks when Windows reports that no audio output device is installed.^1^
2. Install the correct driver
If the device is still missing:
- Identify the exact laptop model. It is usually printed underneath the laptop. You can also press Windows key + R, enter
msinfo32, and check System Model. - Go to the laptop manufacturer’s official support website.
- Search for that exact model.
- Select your installed Windows version and download the latest Audio driver.
- Install it, restart the laptop, and check the Sound settings again.
A manufacturer driver may be available even when Device Manager says the best driver is already installed.^2^
3. If the audio device appears but still does not work
Reinstall its driver:
- Open Device Manager.
- Expand Sound, video and game controllers.
- Right-click the audio device and select Uninstall device.
- Confirm the uninstall when prompted.
- Select Start → Power → Restart—do not only shut down.
Windows should attempt to reinstall the device after restarting.^2^
4. Additional Windows 11 check
On Windows 11:
- Open Settings → Windows Update.
- Select Check for updates and install available driver updates.
- Restart the laptop.
- If necessary, open the Get Help app and run the automated Audio troubleshooter.^1^
If the audio hardware remains completely absent from Device Manager after installing the exact manufacturer driver and scanning for hardware changes, contact the laptop manufacturer; the remaining issue may require hardware or firmware diagnostics.
Windows 10 note: Microsoft ended free Windows 10 support on October 14, 2025. If the laptop supports Windows 11, upgrading is recommended.^1^
