@Larrimore, Welcome to HP Support Community,

Thank you for posting your query; I’m here to help by guiding you through steps to resolve this issue

Sounds like your laptop is playing the silent game, huh? No worries, we’ll get your HP Envy humming again! 🤫🎶

Here’s the plan: we'll start by checking the basics, like making sure everything’s plugged in and the volume isn’t secretly taking a nap. Then, we’ll work our way through updating and reinstalling drivers, like a digital doctor checking for all the right connections. And if things still aren't singing, we might even try coaxing the system with a restart or a quick system restore – sometimes, a little TLC goes a long way.

Check Physical Connections

• If you're using external speakers or headphones, ensure they're properly connected to the headphone jack or Bluetooth settings.
• Try plugging the headphones or speakers into a different port or device to confirm they're working.

Restart Your Laptop

• Sometimes a simple restart can fix temporary glitches with the audio.

Check Audio Output Settings

• Right-click the sound icon in the taskbar and select Open Sound settings.
• Under Output, ensure the correct audio output device is selected (e.g., speakers, headphones).
• If no devices are listed, right-click in the sound settings window and select Show Disabled Devices. If your output device shows up, right-click and enable it.

Check Volume and Mute

• Ensure the volume is not muted or set to zero in both the system volume and application volume.
• Also, check the hardware volume buttons (if any) on your HP Envy and adjust the sound level.

Update Audio Drivers

• Right-click on the Start menu and select Device Manager.
• Scroll down to Sound, video and game controllers.
• Right-click your audio device (e.g., Realtek Audio) and select Update Driver.
• Choose Search automatically for updated driver software.
• If the system finds an update, follow the prompts to install it. Restart the laptop afterward.

Reinstall Audio Drivers

• In Device Manager, right-click your audio device and choose Uninstall device.
• After uninstalling, restart the laptop. Windows will attempt to reinstall the audio drivers automatically.
• Alternatively, you can visit the HP Support website, find your specific model, and download the latest audio drivers directly.

Check Audio Services

• Press Windows + R to open the Run dialog, type services.msc, and press Enter.
• Scroll down and look for Windows Audio.
• Right-click on it and choose Restart.
• Ensure the startup type is set to Automatic.

Run the Audio Troubleshooter

• Right-click the sound icon in the taskbar and select Troubleshoot sound problems.
• Windows will attempt to detect and fix any issues automatically.

Check for Windows Updates

• Go to Settings > Update & Security > Windows Update and click Check for updates.
• Install any available updates, as sometimes they contain fixes for hardware or driver issues.

Check BIOS Settings

• Restart your laptop and press the ESC key repeatedly during startup to enter the BIOS menu.
• Navigate to Advanced > Device Configuration and ensure Audio is enabled.
• Save the changes and exit the BIOS, then restart your laptop.

Check for Hardware Issues

• If none of the above step's work, you may be dealing with a hardware problem. Try using external speakers or Bluetooth headphones to see if the issue is with the internal speakers.
• If external devices work fine, there may be an issue with your laptop's built-in audio hardware.

Perform a System Restore

• If the issue started recently, consider performing a System Restore to return your laptop to a point before the sound issue occurred.
• Type System Restore in the Windows search bar and select Create a restore point.
• Under the System Protection tab, select System Restore, then follow the instructions to restore your PC to an earlier state.
