Distortion at lower volumes when using a volume pot #81

I added a 20kΩ pot and now I can hear distortion in the higher frequencies when the volume is set low.

Do you hear the distortion only when you move the pot down or do you hear it, too when you deactivate the pot and turn down the volume with the slider in the web app?

The distortion is more audible when the pot has higher resistance and the volume is lower. There is no distortion due to moving the pot and when the pot is deactivated.
