I write: yes, that is how it was set yesterday, and that's how it's set today. Still not working.
The thing that really gets me is that I'm doing exactly what I did yesterday, it worked beautifully, and I'm getting nowhere today.
I should also add that I have the latest drivers for the Saffire 6, before someone posts to tell me to get the latest drivers.
Thanks for your reply, HangTime. What now?
Actually, I've solved the problem: Audio Midi: Format: choose 48000.0 Hz, at which point, it switches to 48 and then automatically back to 44, and *bingo*. Problem solved. Simply leaving it at the 44 default did nothing. But clicking the drop down menu and choosing the 48 option must've made it "wake up," or something, and realize which setting is correct for compatibility.
Thank you for pointing me in the right direction!
