Windows Media Player error C00D11BA
Windows Media Player can't play the file because there is a problem with your sound device, such as a sound card or sound controller.
Things to try:
Quit other programs that might be using your sound device, and then try to play the file again.
Install an updated driver. To see if an updated driver is available, use Windows Update, go to the sound device manufacturer's website.
If you have multiple sound devices installed on your computer, try using a different one. The selected sound device might not support Secure Audio Path (SAP).
To use a different sound device
Make sure your sound device is working properly. To troubleshoot device problems, see Windows Help and Support or refer to your sound device's documentation.
Make sure you have a sound device installed on your computer. If not, install a sound device (such as a sound card), and then try to play the file again. If you can't install a sound device in your computer, you might be able to resolve the problem by attaching USB-based headphones or USB-based speakers to your computer instead.
