Aggregate Audio Issues in my World - a simple solution

I came out the box for the Sons and Daughters LP Mix, and it was a new experience for me. I have successfully tracked in the past with my ULN-8 and my Ensemble at 44.1k so I was hoping for a simple and stable solution again - though this project was 96k. I had quite a few problems - interfaces not being recognised, terrible glitchy audio, no audio, Logic complaining about wrong sample rate and more. I had to replace the firmware on the ULN-8 and the Ensemble although both were already at latest firmware and latest drivers when I started the project, it seemed they became corrupted. Shutdowns did not always solve the problem, and though I was enjoying the project, the music, the audio and the challenge I found it very frustrating at times, and wondered if my system would be more stable with 2 Ensembles or 2 ULN-8s instead (though I would still have to aggregate). I also considered (and am still very interested in) a non aggregate 16 output system using an Aurora 8 hooked up to my ULN-8.

After reinstalling the firmware on the Ensemble I followed the instructions exactly and switched on the computer before powering up the Interface. This made me think that switch on order might be important, so from then on I booted the computer before switching on any Audio Interfaces. This seems to work very much better, and now my system seems to be stable and very useable.
