Aggregate Device help
I've taken the steps outline at http://www.apple.com/pro/techniques/aggregateaudio/ to set up an aggregate device consisting of my M-Audio Firewire 410 (4 in, 10 out) the Mac built-in audio in (2 in) and the Mac built-in audio out (2 out). I've checked several times and I've followed the steps exactly, as well as looked at past posts here to confirm.
When I go into Preferences --> Audio in LE 8, the aggregate device is not available to me in the device dropdown. Only my physical devices are there (ie: the 410 and the built-in I/O). For what it's worth, I also launched Garageband just to see it showed as an output option -- it did not.
Furthermore, when I relaunch Audio Midi detup to see what's going on, the agg device I had just set up is no longer there -- as if it didn't "save."
Any help is appreciated.
thanks
