0xC00D11BA: Cannot play the file
Windows Media Player cannot play the file because there is a problem with your sound device, such as a sound card or sound controller. You may encounter this error message for one of the following reasons:
Your sound device is in use by another program. Quit other programs that may be using your sound device, and then try to play the file again.
Your sound device is not functioning properly. To troubleshoot the problem, see the Sound Troubleshooter in Windows Help or refer to your sound device's documentation.
You do not have a sound device installed on your computer. Install a sound device, and then try to play the file again.
Error ID = 0xC00D11BA, Condition ID = 0x00000000
Error 80040256/00040258 (No audio hardware is available, or the hardware is
not responding) and C00D11BA (Cannot play the file because there is a
problem with your sound device) along with most sound card related problems
can be fixed just reinstalling the drivers for the sound card.
Windows Media Player uses DirectSound to interface with the sound card, so
sound very well might work in other applications and just not WMP. More
information and tips can be found at
http://www.zachd.com/pss/pss.html#audio.
If reinstalling the drivers doesn't fix the problem then the next step you
should try is updating/reinstalling DirectX. DirectX can be downloaded at
http://www.microsoft.com/windows/directx/default.aspx?url=/windows/directx/downl
oads/default.htm.
If you need help locating where to get the latest drivers for your sound
card try the following. Your Device Manager in Windows "should" supply the
information assuming the sound card has been detected. To access the Device
Manager right click on My Computer and select the Device Manager tab. In
Windows XP goto the Hardware Tab and select Device Manager.
If you don't know how to access the Device Manager or it doesn't show your
card, than the easiest thing to do is download a free utility like Belarc
Advisor (http://www.belarc.com/free_download.html). Run the installer then
it will open a webpage for you. Under Multimedia it will tell you the sound
card or "Audio Controller" you have in your PC. You may now goto that
companies website and download the drivers and reinstall them.
And if that doesn't help you will need to provide all the information you
can about your system in a reply in the newsgroup.
http://www.zachd.com/pss/pss.html#isolate will help you supply good
information to your peer's to help you out.
