Yes, I have. Here are the instuctions I used:
A few people have commented about not getting the Vista audio DSPs with some devices. It appears possible - at least in some cases - to make Vista's native audio DSPs show up for a device that does not normally have them:
1. Insert some generic USB audio device and let Windows install the built-in USB driver for it.
2. Open regedit and navigate to HKEY_LOCAL_MACHINE\\Software\\Microsoft\\Windows\\CurrentVer sion \\MMDevices\\Audio\\Render. You will probably see several keys with names that look like a guid surrounded by curly braces. Find (i) the one for the USB device installed in step 1 and (ii) the one for the device that you want to enable Vista's native audio DSPs for. Oftentimes the name of the device is visible as a string value under the "Properties" subkey.
3. File->Export the "FxProperties" subkey of the USB device.
4. Edit the .reg file saved in (3) and replace the GUID of the USB device with the GUID of the device that you want to enable Vista's native audio DSPs for.
5. Change ownership and/or permissions on the key that the .reg file now points to in such a way that you can write to it.
6. Import the .reg file modified in step 4.
- registry modifications are dangerous, so only do this if you are comfortable with this sort of thing
- do not count on meaningful help from tech support if something goes wrong
- step 5 may involve some frustration, so start with a fresh supply of patience
- if the hardware originally came with its own audio DSPs, those DSPs may disappear. Reinstalling the driver seems to restore the original state.
