Dear Friends,

I am using WM8727 codec with AT91SAM9G45 processor. I have implemented
machine code as http://pastebin.com/axadqGhd .

After insterting the module I got following output:
# insmod sam9g45_wm8727.ko
atmel-pcm:preallocate_dma_buffer: area=ffadf000, addr=77c40000, size=32768
asoc: WM8727 <-> atmel-ssc0 mapping ok

I am getting following error when I tried to play the wav file using
command "aplay -D default sample_16.wav ":

atmel_ssc_startup: SSC_SR=0x192
Playing WAVE 'sample_16.wav' : Signed 16 bit Little Endian, Rate 44100

Does anyone throw some light where and how to solve the issue? Kindly
share if one needs further information.

Have a Good Day,
Thank you,
