Gotcha...thanks for the link. Interestingly enough, it seems that I wouldn't actually need a free PCI slot:



...I'd just need to provide power to the proper pins/traces on the card via a old PCI slot that I could salvage from some motherboard. And since it conforms to the PCI standard, identifying the proper pins should be dead simple.

I read some of your other threads, and it seems like you decided to go with this card as a solution because it allows you to use whatever sound card you want, and then essentially provides noise reduction, echo cancellation, and timing adjustments to whatever signal passes through it. If that's the case, then I think it would even work with speaker path length timing adjustments from the sound card, since the delay would be present in the original signal.

Interesting product. If I get into bluetooth audio with SD, then perhaps it will be worth the investment. Thanks for the info...I'm surprised I haven't seen this car mentioned other places on the forum.
