My bad. An audio interface, such as the onboard thingy or an USB audio interface could provide for example S/PDIF. USB is good, but using more than one audio interface comes with pitfalls. >But in my case just the one microphone array is all that will run at >the same time, and I want it connected directly to my PC, so USB or >PCIe seem like the most natural interfaces. So for recording you just need one USB microphone, but for playback you still need another audio interface. Most likely you will use your on-board audio device. Most likely you mobo provides S/PDIF, so from my point of view, I would tend to go with S/PDIF instead of USB. My point of view is biased, since I'm a pro-audio user. IOW I try to ensure that jackd usage is as easy as it could be. If you are using pulseaudio, my thoughts might be absolutely irrelevant. As a former audio engineer who worked for one of the two famous German microphone companies, my intuitive thought is still to prefer S/PDIF over USB. Perhaps I'm just a dino who missed that all gear nowadays is equipped with USB. In my experiences a lot of consumer gear provides S/PDIF, but not necessarily USB, so assumed you one day want to connect your digital microphone to some other equipment (not to a computer), there might be no USB port available, while S/PDIF usually is available.
