I can't find a stereo mix option under alsamixer I would like to use the alsa loopback driver to stream what I hear from my speakers over flash webcam sites but I can't figure out how to get it to work. I load the driver using "sudo modprobe snd-aloop" and I can select loopback in flash but there is no sound. and when I select it in alsamixer it says "This sound device does not have any controls." What do I need to do to be able to record what I hear from my speakers in on flash websites?
