Someone asked about recording under linux recently, and I recall that
several of us said we'd never been able to do it. I just did it.
In alsamixer, space bar sets the channel you want to use for capture.
(line in is a reasonable choice)
Had to manually edit /etc/asound.conf to turn on the input gain and set
the level to 10,10. It looks like this:
element("Input Gain Switch",0,101,Switch2(on))
; Voice 0 : Min 0 Max 15
; Voice 1 : Min 0 Max 15
element("Input Gain Volume",0,200,Volume1(10,10))
