Fire up Ardour and record 32 channels of audio at the same time set to <5mS latency using Jack and see if whatever version of the mainline kernel you are running doesn't have. I've recorded as many as 48 channels @ 48KHz across three hard drives at less than 2mS on my main recording platform, but that requires rt-sources. I doubt I could do better than about 25mS with vanilla-sources. Just my experience, Mark
