Comment 3 for bug 369460

After further investigation I realized that I had to use "Configure channels" in Kmix to bring settings for microphone input ; now I can manage full sound settings with Kmix with microphone ; if I open gnome-volume-control record with microphone is muted so apparently now the conclusion is that gnome-volume-control is somehow problematic as whereas Kmix shows microphone input unmuted gnome-volume-control shows it muted.

Now with Kmix I have audacity and skype working.
Regards.
