If you run linux on the mac mini, see below. As for mac os: i hardly ever
use it. It came with a driver cd rom to use the S24_3LE mode plus the midi
port on mac os/windows, plus sonar le for windows. Without the enhanced
drivers aparently it will only with in S16_LE mode. The CDs are still
unused, as the (wonderfull!) snd-usb-audio driver work with both enhanced
and non-enhanced mode.

Both kinda. Last time I looked it had not been applied, and jackd does not
start without it. With the patch recording levels show up wrong, but I'm
mostly there makeing a fix for that.
