Hi All,

We have a driver that supports dynamic format changes on windows 7. I tried
same driver on windows 8 and here is what I have observed:

- When I change sample rate, Sound and audio control panel correctly
updates the sample rate list to reflect the formats related to new sample
- The default selected sample rate is set to previous/last selected sample
- When I try to play something in media player after changing sample rate,
Sound and Audio CPL uses old sample rate.

Is this a bug in Windows 8 or has anything changed on windows 8??
