Perhaps your microphone needs +5V bias to be switched on. Mine does.
Look for this setting in /etc/asound.state - mine reads...
control.44 {
comment.access 'read write'
comment.type BOOLEAN
iface CARD
name 'Mic +5V bias'
value true
Also gamix (a very nice Alsa mixer for X) has a button to enable this.
