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.
