Hi I go to play something and i get this message Windows Media Player cannot play the file because there is a problem with your sound device. There may not be a sound device installed on your computer, it may be in use by another program, or it may not be functioning properly. I click more info and get this 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 any ideas? ta

Do you have sound when you use windows normally? try to make the computer play something in other than w/m/player. if you do have sound then I'm not sure, but if you have no sound at all, you could try re-installing the sound card. maybe you have a pci soundcard that is conflicting with an on-board soundcard that might need disableing. check control panel/ sounds. if in the hardware tab, your soundcard device is different to the one installed, then try choosing the correct card. hope it helps.

cheers,will give it a go.nothing works at the mo seems to have disabled the sound card for no reason.
