======================================================================
Summary: (Apparently) no microphone support
Description:
My SB Live! 24-Bit has no microphone-related channels. Using any mixer
(tried: alsamixer, kmix, gnome-volume-control), it seems not to support
microphones.
Audacity shows very small (pixel-size) distortions in the recording graph
at times. I presume this means that the input is being received, but is
too miniscule to make a difference. I can't do anything about this; there
are no appropriate sliders or "mic boost" in any mixer application.

alsa-driver must be compiled with the same version of GCC as the kernel.
Please compile and install your own kernel and then try alsa-driver again.
