Try this (which solved my problem, see
 Message-ID: <20080407090601.GA3251 at rebelion.Sisis.de>):

$ mixer vol 66:66 pcm 40:40 speaker 66:66 line 66:66 mic 66:66 rec 66:66 +rec vol

the crucial part is '+rec vol' changing the recording device to 'vol'
and recording is now fine with this, even if I never ever will
understand what 'volume' has todo with input/microphone :-)
