[meta-freescale] Question about test audio record.

[Mingtao Qu]

Hello everyone.
   I tests audio recording use arecord on imx6q sabre auto board, but I 
got nothing.
   The kernel version is 3.10.17.
   when running arecord, I2C bus command has been committed, the cs42888 
codec register value can be dumpped by i2cdump. but no sound captured.
   The mic already passed testing on pc.
   Any can give me some ideas ?
