Due to lack of documentation the AMIC4 and AMIC5 analogue microphones were never actually working, so the audio routing for them was added hoping it is correct. It turned out not correct - their routing should point to SWR_INPUT0 (so audio mixer TX SMIC MUX0 = SWR_MIC0) and SWR_INPUT1 (so audio mixer TX SMIC MUX0 = SWR_MIC1), respectively. With proper mixer settings and fixed LPASS TX macr codec TX SMIC MUXn widgets, this makes all microphones working on HDK8450.
