Searching for a clue. What is the best setup for a PC based system streaming to an Airport Express. I mean what needs to be turned off or on in XP to make things good. I've got the Itunez stuff all off, but what needs to be done to the OS? I've heard that the kernel for audio in windoze is a baddie, what to do here? and elsewhere. Input welcomed. I'll hang up now and listen to your response.
