I just bought a new computer and am in the process of setting it up.
As it does not have a soundcard with a digital out (yet), I connected my Grace M902 DAC/headphone amp to a USB port and put in a CD. It sounded quite good.
However, now the sound is very garbled. This is not a jitter issue. It sounds as if the digital input is overdriven (you know that horrible, ripping sound that an overly hot digital signal can create).
Any ideas for a solution? Any idea what changed?
There is not heavy I/O going on or anything else that I can think of that would cause the problem. I just want the USB to work until I get a soundcard installed, etc.
Of course, I would like it to work just because as well. 
I am using XP Professional and am very comfortable with computers. The only real change was to download all the XP updates but I don't know if this affected the USB output.
