no operation audio

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.

HI kim

I would suggest to check codec connections with SDK (wm8962.c)

audio test

i.MX 6Series Platform SDK : Bare-metal SDK for the i.MX 6 series

Best regards

igor
