Hi @Leedom,

Welcome to HP Support Community.

Thank you for posting your query, I will be glad to help you.

Error Code 28 indicates that the drivers for your device (in this case, the digital microphone) are not installed. Here’s how to troubleshoot and resolve the issue.

Reinstall the Microphone Driver

1. Open Device Manager:
   • Right-click the Start button and select Device Manager.
2. Locate the Microphone:
   • Expand Sound, video and game controllers or Audio inputs and outputs.
   • Look for the Digital Microphone (it may have a yellow exclamation mark next to it).
3. Uninstall the Driver:
   • Right-click the Digital Microphone and select Uninstall device.
   • Check the box that says Delete the driver software for this device if available.
4. Restart the Laptop:
   • Upon restarting, Windows should automatically reinstall the correct driver.

Update the Driver

1. Manually Update Driver:
   • Open Device Manager.
   • Right-click the Digital Microphone and select Update driver.
   • Choose Search automatically for updated driver software.
2. HP Support Assistant:
   • Download and install the HP Support Assistant from the HP website, which can detect and install the correct drivers for your microphone.

Check Windows Audio Settings

1. Microphone Privacy Settings:
   • Go to Settings > Privacy > Microphone.
   • Ensure that Microphone access for this device is turned on and that apps have access to it.
2. Sound Settings:
   • Right-click the Speaker icon in the taskbar and select Open Sound settings.
   • Under Input, make sure the correct microphone (Digital Microphone) is selected.

Windows Troubleshooter

1. Run Troubleshooter:
   • Go to Settings > Update & Security > Troubleshoot.
   • Select Recording Audio and run the troubleshooter to identify any potential problems.

I hope this helps.

Take care and have a good day.
