@BonukaSageeth, Welcome to HP Support Community. 

Thank you for posting your query, I will be glad to help you. 
If your HP desktop's sound is not working on Windows 10 (64-bit), here are some steps to help you troubleshoot and resolve the issue:

Check Physical Connections

• Ensure your speakers or headphones are properly plugged in.
• If using external speakers, verify they are powered on and volume is turned up.

Set the Correct Playback Device

• Right-click the speaker icon in the taskbar → Sounds → Playback tab.
• Select the correct audio device (e.g., “Speakers – Realtek High Definition Audio”) and click Set Default.
• Click OK to save.

Run Windows Audio Troubleshooter

• Go to Settings → Update & Security → Troubleshoot → Additional troubleshooters.
• Select Playing Audio → Run the troubleshooter.
• Follow the on-screen instructions.

Update or Reinstall Audio Drivers

• Open Device Manager (right-click Start → Device Manager).
• Expand Sound, video and game controllers.
• Right-click your audio device (e.g., Realtek, Conexant, etc.) → Update driver → Search automatically.
• If that doesn’t help, try Uninstall device, then restart your PC to reinstall it automatically.

You can also manually download the latest audio driver from HP: Official HP® Support

Enter your desktop model number to find the correct audio driver.

Check for Windows Updates

• Go to Settings → Update & Security → Windows Update → Check for updates.
• Install any pending updates and restart your PC.

BIOS Update (if applicable)

Sometimes audio issues are resolved by updating the BIOS: HP Consumer Desktop PCs - Updating the BIOS (Basic Input Output System) (Windows) | HP® Support
