When you open a saved (USB, Network, Hard Drive, etc.) Excel spreadsheet, it will take 1-2 minutes before the Excel splash screen appears. This behavior should not happen if you open a new Excel spreadsheet and then open a saved Excel spreadsheet.

You can use the following method to help identify if your system has a Realtek audio device.
