The irony of this is killing me. I had a singing capacitor in my 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. -- David gnome@xxxxxxxxxxxxx authenticity, honesty, community
