Hi Frank, Then I would like to remind the convenience of providing either a user mode audio stream hook that intercepts soundcard i/o, or the possibility of user mode virtual audio drivers or filters. This will allow more convenient system wide custom processing, like speaker correction, etc. Jose Catena DIGIWAVES S.L.

Sounds like you're saying "no". That's correct, although on this mailing list there seems to be a bit of a groundswell of desire for such a feature. For those of you watching, now is the time to start lobbying your Microsoft contacts with clear specific feedback on problematic scenarios and feature requests. Hopefully some have noticed that we recently finished one OS so it's time to influence the next. This mailing list did influence Windows 7!
