I am confused when trying to set up the correct recording level using a Behringer UCA222 usb codec. If I adjust the level in "sound settings" I can reduce the input level to avoid clipping. However, if I reduce the level in pulse audio volume instead, the clipping remains. Do these two controls act in different places in the audio chain? If so, where?
What also puzzles me is that the codec does not seem to have a capture level control to allow the level to be reduced before ADC so how does the "sound setting" level avoid clipping?
Any light gratefully received.
