Your screenshot corroborates the fact that mic boost is zeroed, which generally results in very quiet or inaudible capture:

Simple mixer control 'Mic Boost',0
  Capabilities: volume penum
  Playback channels: Front Left - Front Right
  Capture channels: Front Left - Front Right
  Limits: 0 - 3
  Front Left: 0 [0%] <---
  Front Right: 0 [0%] <---

You actually need to set the slider to 100% or higher.
