You're ranting about Alsa, not Fedora. All the other modern distros use Alsa too. The core trick to recording stuff is to understand that the default pane of controls in Alsamixer and kmix is only to do with playback. If in that pane you unmute Mic and turn it up, it will loop back the mic data from the mic channel to the output without recording anything. The usual result of that is howling feedback. What you want is in the second pane of alsamixer, which you get to with a Tab key, this deals with the input sources. You need to select a recording source by using the left/right arrow keys to navigate to it a space to enable it as an input source. In kMix its the same deal with a second tab pane having these controls and a circle above each source you click on to select. Sometimes what the driver reports about the mixer controls doesn't reflect reality. In these cases the wrong buttons and sliders do the wrong job. Most of the time though it does work after some meddling on your part. -Andy
