Yes, you are correct. For sending PCM via USB you don't need any sound "card" or chip to get involved. Make sure you use a player and "kernel streaming" to bypass Windoze internal mixer. There's a couple documents around that can help you set up the player. The Ayre site has one and so does the dCS site. And there's probably others. Sorry I don't have pointers to them easily accessible. There are links to them in some posts in this forum.
