BTW, are you able to run jackd with the UA-20?
I get a message saying "your device either doesn't support one of the
two sample format jack can use" or something similar...
I have the same problem with my usb imic. Has anyone got jackd
running with a usb audio interface? The sound is clipped with pd/ alsa
as well.
(no ground loop hum on the imic though - maybe because its low
power)
cheers
