Today I had to unhook my Mac Pro and take it to the Mac store for an unrelated install problem I was having. I was careful when hooking it back up to plug everything in just as I found it. I have 3 interfaces: a 2408 mkIII, and two 24 i/os. The 24 i/os are labeled 24 i/o-2 and 24 i/o-3.
The audio wire plugs for all 3 interfaces are taped together so you can't switch the order.
Why then, has DP 7.23 relabeled all my interface settings with the wrong units? ie: my main output and input were ch.1-2 of the 24 i/o-2. But now all my projects have the stereo outputs labeled as 2408 mk.III. And the 24 i/os are marked as 24i/o-3 and -4! What the heck? Same thing in my MOTU PCI audio setup. I tried to open the audio/MIDI setup, and that main screen wouldn't even come up. Everything is changed. (I think my MIDI functions still work) Why would DP do that, and how do I fix it without having to change every F*%#>^+ track on every tune?

P.S. when I do change the output of a track to ch. 1-2 of the 24 i/o-3 I do get audio.
