Some programs, like Spectran, have the possibility to make the processed signal heard via the PC speakers.
But my problem is that the use of  filters provided by the program does not make any difference to the audio at all. The spectrum is nicely displayed, so there is no problem on that side.

The same problem exists with other programs that are supposed to provide audio filtering via the computer.  What comes out of the PC speakers is the signal at the input of the sound card.
Jan Harte, PA0HRT, experiences the same problem.

Whatever is done with the volume controls, nothing helps.

Any suggestions?
