Thanks. Okay did that :)
1. Got jack running. No problems

2. Started alas_in with
      alsa_in hw:4,0
It says:
bob$ alsa_in hw:4,0

Cannot lock down 82241434 byte memory area (Cannot allocate memory)

selected sample format: 32bit

delay = 1019
And run audacity which gives me another input selection "alsa_in".

Only problem is that when I record from this I get static. Recording

from plain alsa works okay, so the device/mic are problably okay.
So, I probably need to do more in setting up the alsa_in other than

the defaults? Not sure what though.
