Jim,
If I understand your question in the subject line (but no text to detail
your question) - then the answer is that it all depends on the
soundcard. If it has a DC blocking capacitor in the input, then all is
well with the bias resistor in place. If there is no DC blocking at the
soundcard, the the bias resistor will have to be removed or a special
cable with a DC blocking capacitor will have to be inserted between the
mic input and the soundcard AF input. A capacitor of 1 to 5 uF should
do fine.
If this does not answer your question, the respond with more text
instead of us trying to guess from just a subject line.
73,
