USB Audio Dongle w S/PDIF Out

Does anyone have any experience using a USB audio adapter with mm? I would like to use DTS/AC3 passthrough for my home theater frontend, but the mini Dell boxes I'm using only have analog out. Here's one I'm considering due to the fact that I'm cheap. ... -US711.htm

I've found a cheaper one ($10 + s&h at, but it's not in a dongle form and I'd like to stick with something that's self-contained.

Sadly, none of the manufacturer's sites specify the chipset being used.

I can't help you but I'd appreciate hearing if it works, or not.

If this works for you, it will be a huge benefit for HTPCs. I'd go with the USB unit, also.

I've decided to go one cheaper and attempt to 'graft' a digital interface onto the motherboard directly. The AD1981B audio chip has the S/PDIF pin located in an easily accesible spot, and all I should need in addition to that is power and ground (also conveniently located). All that's left is to find a donor optical adapter in an old DVD player or satellite receiver.

If that fails I'll either punt with the USB dongle or splurge on a complete ION based board.
