I have a sonica theater and I have had no problems. But, I only use it for analog 7.1 output, not sp-dif. So that does not help you one bit.
If all you want is a "usb-to-spdif" converter, turtle beach makes one that is considerably cheaper, I think about $25 from buy.com and other places. Sorry, I don't remember the model name.
