It seems that forcing the new sample rate by writing the rate directly
to the registry works pretty well. The method is described in:
"Vista Core API: Changing audio device sample rate via
PKEY_AudioEngine_DeviceFormat does not work"

Hello!
we have a USBAudio device that works fine under Windows XP (HCT tested).
With the device we ship a configuration tool that permits the user to
select the supported sample rates and formats of the device (->
configuration of the embedded firmware).
After a reset, the device it supports only the new configuration, but
under Windows VISTA the old and new sample rates and bit depth are
shown in the "Volume Control Properties Advanced tab".
Each of the shown formats (the old and new ones) when selected as
default format fails then with the Test button.
Neither unplug and replug the device nor a reboot solves this problem.
The only way I found is to manually uninstall and reinstall the
device in the DeviceManager. After this action the device works
correctly with the new formats.
Are there easier ways to solve this, or do we have to integrate the
re-install-process in our application ?
