Hello Henny,

If you turn down the gain of the = 'output=20 amplifier' in the circuit window, does the sound from the soundcard = disappear=20 (it should) ?

If not, I guess it's the old 'mixer' problem = again - many=20 soundcards are configured to route the input (from the "line in" jack) = directly to the output ("line out"). SL doesn't touch any of the = soundcard=20 settings, so you need to find the right control (slider, or mute = option) in=20 the soundcard's audio volume control panel (sndvol32, or whatever = program came=20 along with the soundcard).

The effect of the hum filter should = be=20 easily audible, because that's what it was designed for. Btw for = 'natural=20 radio' listening, the FFT-based automatic multi-notch filter is = preferred over=20 the old hum filter (=3Dcomb filter).

All the = best,
