Dear all

We use a new board was produced i.mx6q cpu . Please refer to the following log files. I do not know why the log file does not proceed further. However, the camera and movie works well . But the sound is not the behavior . The audio chip is used wm8962. movie play audio interface signal when the output does not come from i.mx6q .

Please tell me why why.
