Hi Stefan, thanks for your reply. I have followed your suggestions and everything seems to be running. I can start the Jack server, and I can even define different audio cards for input and output. It works!
However nothing comes out of the speakers. I have checked Alsa mixer and all the lines are in maximum volume. I am sure that the signals arrives to the PC, because I can record in Ardour and I can see the waveform, but I cannot hear anything. Not even if I play the track recorded in Ardour. Any idea?
