I just installed Natty for the first time tonight. This time around, I went with Xubuntu and installed the Ubuntu Studio packages on top of that. As Scott mentioned, I needed to add myself to the audio group, but after this my equipment immediately worked. Unlike previous versions, there was no need to change any configuration files to get access to my firewire device, which means that Ubuntu Studio is basically working out of the box for me now (or, it would be if I had installed from an Ubuntu Studio disc). Yay! For a test run, I did some mixing on a recording I'm working on right now. I started out using the generic kernel, and performance was surprisingly solid. There were a few x-runs when starting up or switching between applications, but otherwise it was usable. I then installed Allessio's low latency kernel, and proceeded to mix for an hour and half without a single x-run, even when starting up applications and switching between them. Rock on! So, I can say definitively that the low latency kernel gives me better performance over generic. This test was run at 44.1 khz / 512 frames / 3 periods - getting about 34.9 msec latency. The next time I get the chance, I'll set up some mics and do a recording test at lower latencies (I'll push it to 128 frames, which will take it down to 8.71 msec latency. This is something I have been able to do previously using rt kernels) and see how it performs. So far so good.
