Q: AU-Lab set-up?

I went through hours of trying to get AU Lab to show any of the different audio sounds that I need to record .

I tried every possible variation of inputs and outputs I could think of. Internal or external audio (through my

Alesis iO|26). I have been recording with Logic Pro Logic Express and my Alesis sucessful for years, but

have yet to see any movement in AUs level meters no matter what settings I try. Since AU was made by Apple

I must be not finding the right initial settings to get started with AU Lab. I also tried to use soundflower with AU Lab.

Would sombody please talk me through the first set-up of AU Lab.

Thank you so much for your time and patience.
