thanks..but it doesn't quite work that way.....in my case..I have m-audio mobile pre as my main output...the windows audio..at the bottom right task bar is set to the mobile pre... yet, in all other applications that I use, the windows drivers are simply skipped, since I can select the m-audio as a default. I can completely mute or not run the default windows driver on everything but iTunes..and yes I realize that the windows default in my case is acting as a simple gateway to my m-audio driver, but it makes no sense to me why a selection panel can't be added to itunes itself... this would actually open up iTunes to multiple instances on one computer..out different drivers..that part means nothing to me, but illustrates that it runs through channels that it doesn't have to..and takes resources that it shouldn't need.I can work with it..but it seems that we need to advance software by making it more specific in the future.
