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 rate. - The default selected sample rate is set to previous/last selected sample rate. - 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?? cheers Neetu
