Hi,
I am developing for Windows 8 Store and i have a media application which plays audio with MediaElement component (C#, XAML).
It has ATI 4890 display adapter. I have installed windows 8 to an empty disk and everything worked perfectly without installing any drivers. My media application stopped playing (actually not changing state to Playing, but buffering/initializing...) after installing AMD's Windows 8 drivers located at this page: http://support.amd.com/us/kbarticles/Pages/catalystlegacywin8.aspx (I have reached to this page by selecting appropriate hardware and software from the main AMD site)
After installing ONLY display driver, the app stopped working. Uninstalling only "display driver" fixed the problem.
So the default WWDM 1.1 driver by Microsoft works PERFECTLY. If i install the AMD version, it breaks many media applications those use MediaElement/MediaPlayer component. As far as i understand, this is not happening only for old display cards, but i also tried it on the newest laptop computers too, some of them are suffering from the same problem too. So this may be a general bug either inside of Microsoft's Windows Store SDK or AMD's driver.
I have the following details:
