I''m running a much older system w/ Win 98SE. For no reason that I can figure out I have lost the sound while playing either Windows Media Player or Real One Player. My windows sounds and all game sounds are fine. When trying to play a .wmv file with WMplayer I get the following error 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."

When I ask for more information I get the following message.

"Windows Media Player Error Message Help

You've encountered error message C00D11BA while using Windows Media Player. We are investigating the cause of this error. We will post more information about this error when it becomes available. "

Can anybody help me???

Use a different media player. try Winamp

I have seen this problem before. If i am not mistaking it was a codec issue. I would try uninstalling/reinstalling your sound drivers.

also what version of windows media player are you using.

try doing a windows update and install the newest windows media player and the media player codec.
