Hello all-
I've been setting up a digital audio workstation
using Fedora 8 and the
PlanetCCRMA realtime kernel.
I've got an M-Audio Fast Track Pro connected via USB
for audio and MIDI i/o.
A log of my efforts is here:

Everything has worked out great so far, *except* for
recording.
When I attempt to record audio using the Fast Track
Pro, I hear a *lot* of line
noise. It doesn't seem to
matter what input I use (1/4" jack or XLR), nor does
adjusting the sample rate or frame count. I get the hiss
recording a guitar (direct line) or mic. I don't see
any xruns.
The Pro appears to have some sort of noise gate?
Certainly it is quiet until I
start playing, at which point
I'll hear the guitar plus a lot of hiss. Other parts of
my sound gear don't show this symptom.
Any ideas? I'm hoping this is due to bad
Alsa/JACK settings and not to the
Fast Track Pro.
