I had a problem with WMV Files playing with no sound in WMP 11, it also locked up if you tried to stop, pause or if the file finished playing.
This person also has the same problem, Question # 21807173
I have found a solution but I am unsure exactly what it does.
What I had to do was go to:
And change the AutoInsert value from 1 to 0
This fixed all my problems, sound works and WMP does not crash.
Unfortunately I have this problem in a new image that I created that has already been rolled out to around 80 laptops. I can easily push this registry change out using our login script but before I do I wanted to see if anyone has any ideas to what this registry key is, what it does and if it could cause any other problems.
Any help would greatly appreciated.
Also could someone please update the question that was asked previously (Question # 21807173) with this solution as I believe it was never resolved.
