The irony of this is killing me. I had a singing

notebook computer, which I was able to solve using a load generator at a
low scheduling priority. However, that same capacitor is what had
triggered me to get a higher-end sound card in the first place.
Now this higher end sound card has quite a loud hum when the phantom
power for its mic pre-amps is on. Interestingly, when I mix the signals
from both pre-amps by connecting them both to the same outputs in JACK,
the noises from the Mics cancel each other out.
Sounds like a defective sound card to me. Can you still get warranty
service on it? Chances are they'll readily swap it for a new one.
Or you still have somewhere in your setup a grounding problem ...
Just guessing, haven't any real knowledge myself.
