"below 4ms round-trip latency?" I have not tested round trip. I've been using the (very clean) ADC to record into a buffer. That buffer is played back and modulated in real-time by a variety of sensors. Output has been less than 4ms latency (straight output through ALSA). I think with more tuning of the Pi, kernel, & Pd I could perhaps go lower, but it's not necessary for my current project.
"the audioinjector octo card is actually 6 in / 8 out" my mistake!
