Hi @LatamUser,

Welcome to HP Support Community.

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

If your Realtek sound card has disappeared after a Windows 11 update, and you're seeing issues in Device Manager with an error related to oem112.inf and 0xC00000E5, here’s a step-by-step guide to help you resolve the problem:

1. Check Device Manager

Open Device Manager:

• Press Win + X and select Device Manager.

Scan for Hardware Changes:

• In Device Manager, click on the Action menu and select Scan for hardware changes. This might help Windows recognize the Realtek sound card again.

Check for Missing Devices:

• If you see an entry under "Sound, video and game controllers" but it has an error, right-click on it and choose Update driver.

2. Update or Reinstall Realtek Audio Drivers

Download Latest Drivers:

• Visit the Realtek website or your motherboard manufacturer’s website (if using an integrated sound solution) to download the latest Realtek audio drivers for Windows 11.

Install Drivers:

• Run the downloaded installer and follow the on-screen instructions to install the driver. Restart your computer after installation.

Manual Driver Installation:

• If the installer doesn’t work, you can manually update the driver:
  • In Device Manager, right-click on the problematic device, select Update driver.
  • Choose Browse my computer for drivers.
  • Navigate to the location where you saved the downloaded drivers and follow the prompts to install.

3. Uninstall and Reinstall the Audio Device

Uninstall the Device:

• In Device Manager, right-click on the Realtek audio device and select Uninstall device.
• Check the box for Delete the driver software for this device if it appears.
• Restart your computer. Windows should automatically try to reinstall the driver.

Reinstall the Driver:

• After rebooting, if Windows does not automatically install the driver, use the driver you downloaded earlier to manually install it.

4. Check Windows Updates

Install Optional Updates:

• Go to Settings > Update & Security > Windows Update.
• Click Check for updates and see if there are any optional updates available that include driver updates.

Rollback Update:

• If the problem started after a specific update, you can try rolling back the update:
  • Go to Settings > Update & Security > Windows Update > Update history > Uninstall updates.
  • Select the recent update that might be causing the issue and uninstall it.

I hope this helps.

Take care and have a good day.
