Okay ... good news! Got it all working. And, even better ... I think I might know what's going on (maybe not).

Hooked the same stuff up today. Presonus Audiobox USB with 2 mic inputs, microphone and phones. Now, this time I did one thing first: I turned the inputs in pulse for the audiobox OFF. Then I launched "pasuspender audacity". Did a few tests and all works fine. Even changed the input from 44100 to 48000 and back a few times, worked fine on either setting (assuming that Audacity sets the interface correctly?).

I think the key is to disable the pulse stuff and that a conflict between the 2 was screwing things up. But, I *thought* that pasuspender was supposed to do that?

Only one more issue is that I can't adjust the gain in audacity for the mic. Seems to be a very low signal ... might have to run it though an amp or mixer anyway, but amplifying it after recording seems to be fine.

Thanks for the suggestions!

That could actually be related to the problem: maybe the chipset
supports an IEC958 input and selecting this combination synchronizes the
chipset to the non-existing input.
