I have read the fixes so far for the Apogee Duet under OSX Lion, e.g. killing off "duetDaemon", etc. Here's a new one. Disconnect the duet, run the official uninstaller, and let it reboot. Then plug-in the Duet and re-select it as output device. Now, the Duet seems to work just fine and no killing of processes is needed. Of course, you can't go in and run Maestro b/c it doesn't exist, but when I killed of duetDaemon before it was annoying, it still didn't allow me to use the keyboard volume control for the Duet, and I was getting crackling audio with another drive running off the same firewire port. With THIS method (uninstalling the software) it at least works and you get volume control back. Try it out and let me know what you think! Temporary solution until August, at least.
