Rick, I'm replying since for the past few years I've also used the Xitel hifi-link(also with a Dell Inspiron)to listen, using the USB output, to classical music streamed from all over the world. I haven't had any real difficulties of the kind that you describe and don't have much helpful advice to offer. As you know, the Xitel is simply wires and a DAC, so it has nothing to do with the problem. As long as the multimedia properties screen on your Inspiron shows that the "USB audio device" is still "preferred", it should work, but I don't have any idea of whether the Logitech could have somehow affected this. As usual, see if something in the troubleshooting info in the Xitel manual could possibly apply.
