Well, 4 bits down means the jitter is max 15 counts of the ADC... This is too much!

Cannot understand how can a pot have so much bad connection of its wiper... If you use this port in audio circuit, it should make a lot of noise! Even old and dusty pots, if stationary, do not have such behavior

But then you said that with rotary pots you do not observe any jitter. All the sliders do the same?

If yes, better dump them and get decent ones.
