"Noise" is something :-P

- Check that you are connecting the microphone into the right socket
(usually colored as pink on desktop computers).
- Check that the mic volume is set to a high level.
- Check that the system has configured the proper default mic device as
input source (there can be more than one: front, rear... and must match
to the one you have your mic connected to).
If none of the above works, you can try to define a "model=" for your
sound card (STAC92xx).
