How do i fix error code C00D11B1 Media player 11

Hello i am no computer whiz but could some one tell me in laymans terms how
do i sought this error code C00D11B1 out. I have tried to read the forums
but am getting no where i am running vista business and WMP 11 was playing
my video files untill i updated WMP 11 then the error code pops up and tells
me i have an Audio issue i have followed the links but it does not solve the
issue i cant play any video files at all could some one help please !!!

Do a Google search on the error number.

Completely uninstall WMP11, reboot, and re-install the app.

That wouldn't really do anything useful, isn't generally possible, and isn't
possible on Vista specifically. =\

Uninstall/reinstall should only very rarely work. WMP's world is a little
too complex for that to work. =\

vista wont let me uninstall

Google search has just confused me more with out fixing prob or though
there seems to be a lot of people with the same issues there doesn't seem to
be a one fix solution that i can understand anyway

Have you turned off user account control?

I have the same problem after upgrading my laptop to Vista with WMP 11 I can
no longer play my music files. Other progarms and sound file editors can
play them.
I fixed the video file play issue by installing codecs but I haven't found a
fix for the music files.
I tried downloading the latest WMP 11 but it is still older than the one
installed with Vista and will not install.

I have the same problem... my WMP 11 will not play some video and audio
files... I've tried to read through the questions and answers but does not
seem that anyone have found any solution... if anyone solves it.. PLEASE LET
US KNOW!! thx

What's the exact URL that the Web Help button on the Error Dialog page takes
you to?

I found something that might help you with your problem. This fix is for Windows Vista Home Premium. Go to control panel, then hardware and sound, then click manage audio devices on the sound section. From there you will have 3 tabs click the sounds tab you will notice that your windows sound scheme says windows default modified. Click on the drop down box and change that to just windows default for this is the previous setting. Click apply and test this worked for me.
