jack doesn't care what kind of signals pass through it. > If so, do we have > to worry about speakers blowing up or do soundcards protect against DC? Most audio circuits include "coupling" capacitors that block DC voltages. Transformers work too. I would be amazed if any soundcard will pass a DC voltage. > If not, can anyone tell me what the most CPU efficient way of > modulating/demodulating a control signal might be?
