I am using the SGTL5000 in my design with i.MX6Q custom platform. The codec probing is successful and the device shows up in the alsa device list. When I run the 1kHz sine wave .wav file using aplay command, I am observing the signals on LINE OUT_L only and no signals at LINE OUT_R. Also the signal at LINE OUT_L is not as expected. The sine wave freq is ~520 Hz on the LINE OUT_L pin instead of 1KHz.

I have master clock of 12.2880MHz on the the board. I am also attaching the schematic for your reference.

I am using the driver available on the below link.

Please let me know where I could be going wrong.
