Hi, I have a problem with my mixer that is I can't record line input without simultaneous playback. That's very annoying in my situation because I'm applying effects to the line output of my soundcard with some external signal proccessing hardware. If there is playback when I'm recording the proccessed signal by line input, there is an infinite loop, and that's bad. When I try to set up my soundcard (SB Live!) with alsamixer, nothing happen when I press space bar in order to assign capture to a channel, the red capture label doesn't appear. So know there is something wrong with my setup because I've already used alsamixer before and it was able to set the capture option. If I try a graphical mixer like gnome-alsamixer or kmix and check the recording checkbox for the line input, recording doesn't work. I have to check the recording checkbox for the "capture" channel but then, the recorded sound is played back at the same time, even if line input is muted. However I have no problem to record sound played by the soundcard synth using SoundFonts, I just check the recording checkbox and it works. I don't need to deal with the capture channel. Any hint ? -- Alex
