So please, please, please help me! I'm desparate. I've been working on
linux audio for over four years and my music's starting to get good
enough to be published and I can't record because of some dumb analogue
engineering problem. Are any smart analogue engineers reading this?
Methinks there is Somewheres (note the forced plural!) in your hardware
setup one or more pieces with bad shielding and/or bad grounding. The
problems might not be limited to cabling - they could be something
inside your hardware.
A possible candidate - your fireware audio interface w/ microphone
pre-amp. It may be originating the hum in the first place, and the mic
pre-amp makes it really loud.
