Comment 21 for bug 71704

Having same issue with no capture ability on sb live's line-in when using any recording software. But i found something not mentioned so far, it WILL capture from other external sources such as AUX IN 2, and MIC/LINE In 2 on the Live! Drive (the expansion box that goes in a 5 1/4 slot) and is controllable on the gnome-mixer as Line LiveDrive and Line2 LineDrive under the Capture tab.

Other observations and thoughts:
 In the gnome mixer under Playback tab there is a line-in slider with a little speaker (playback) but no little microphone (capture) exactly as seen in the screencapture above.

 On the gnome mixer under Switches tab (as also seen above) is an oddly placed line-in switch (and also a mic-in more on that later) that when clicked behaves exactly as if you had clicked the little speaker under line-in in the playback tab. It seems this switch should really be on the Playback tab under line-in as a little microphone.

 It seems both alsa and gnome mixers consider any source originating from the pc such as wave, cd, etc as playback and external sources as capture. For some reason the microphone and line in sources are listed under playback and could that be somehow confusing the mixers? How does alsa know what controls to display is there a preset list for each card in the driver or does it probe the card for a list?

 I'll try to dig up some more info on my own but any pointers would be appreciated.
