Desde hace unos dias para aca, cuando trato de reproducir un video, logro ver la imagen pero no tengo sonido. Esto es todo lo que me dicen...

You've encountered error message C00D10D1 while using Windows Media Player. The following information might help you troubleshoot the issue.
Codec is missing
Windows Media Player cannot play the file (or cannot play either the audio or video portion of the file) because a required codec is not installed on your computer.
The codec you are missing is not available for download from this site. You might be able to find it on another site by searching the Web for "55" (this is the WaveFormat
or FourCC identifier of the codec).

Trate reinstalandolo pero no funciona... por favor ayudenmeeee Gracias 

cierto, ultimamente se han visto muchos packs de codecs para media player. buscando un pokito tal ves encuentres como 30
