my suggestion :

use an external USB 2.0 to 3D AUDIO SOUND CARD ADAPTER, you can put all in a small box

Don't forget that you are limited by the frequency response of the sound card.
There are devices which plug into your USB socket, made, amongst others, by
Hantek, e.g. Model DSO 2150, which are more expensive but give better results:

"try to use an serie resistor 1meg  (100k) between pot (slider) and input to card.
be sure thas briund is also connected tocard (otherwise it is try to have problems)
Use shilded (like coax) cables from pot to the card-input

Thanks pese, i will do that. Do you mean ground, when you say 'briund' ?
