Hi,

I'm having trouble to get mic working on this damn Samsung R540. I tried
using linux-image-2.6.26-2-686 (stable/lenny) and
linux-image-2.6.32-bpo.5-686 (backports) with no success. Then I
downloaded latest alsa-driver and tried to compile it against
linux-image-2.6.32-bpo.5-686, but this time I encountered missing files
in linux-headers-2.6.32-bpo.5-common. (Reported the issue to the
debian-kernel ml.) Then I downloaded a vanilla linux-2.6.32.5 and
followed below steps.

Stupid question but did you select the sound capture source and set the capture volume in the sound mixer application ? I have a sound card that uses the snd-hda-intel driver as well and had the same problem, only to find that in addition to the mic volume, I had to set the Capture volume as well to get the mic working.
