Thank you every body for your replies. I didn't know the audio inputs were AC coupled.


Actually, they very often are not AC coupled. You ought to be able to find out if yours are using Audacity and a signal source.

Matlab has a function that can use the sound card for IO, so it is practical.

Arduino is a very simple way to achieve DC analog readings.
