For Boot Manager, I've tested it with BlackICE 1.50, CM7.2, MIUI 2.4.6).
This is "almost" the same inspiremod but with two additional files:
AIC3254_REG_DualMic_MCLK.csv and CodecDSPID_MCLK.txt.
NOTE: installing this in another ROMs may break sound (mic included) specially ICS. I'm not responsible for anything that may happen.
If you have any audio problems just delete the referenced files from /system/etc/.
MAKE A BACKUP FIRST
