Code: C00D11BA; No Audio Device

I am having a HP laptop running with Windows XP and Windows Media Player 10. Since yesterday whenever I’m trying to play any file in WMP 10 it gives me an error message stating: “Code: C00D11BA; No Audio Device”

As per troubleshooting I went to control panel > Sound Devices. Here I found it saying "no audio device". I have sound blaster live 5.1 installed but it won't let me select it as my default sound card. I don’t have any more idea what I need to do to fix this problem.

Please help.

i storngly suspect that the problem is with your sound drivers. What you can do is go to Start/Run, and type DEVMGMT.MSC , highlight the sound device, Action menu, "Uninstall", then restart Windows. Wait for few minutes and let windows install the drivers again automatically. Once done, see if you are getting the same problem again.
