I had a comparable problem (not "mic not found", but "mic-through
can be heared, but it doesn't record anything, in no program").
The solution was to set the gain mixer channels (igain, ogain)
to 100, and then it worked; maybe 0...99 = off, 100 = on? ;-)

So maybe try setting all related channels to 100 first and then
see if you can reduce the level. In worst case, attach an external
hardware mixer to get better level control (which is what I'm doing
at the moment).
