Hi,
I am using imx6ulevk board. I am new in audio codec stuff. Initially I tried with L3.14.38 prebuilt images that I downloaded from the nxp website.
I recorded some sound with arecord utility and played it back to my PC. It was playing well.
Next I tried with L4.1.15_1.1.0_ga_images which was the latest image that I downloaded from nxp website. I tried the arecord utility to record some sound, but it was not geting record. I tried this several times with L4.1.15_1.1.0_ga_images, but I am not able to record anything.
I tried this command:
arecord -d 10 test.wav
Kindly help me in this.

Hi igor,
Thanks for your reply. I have gone through the Linux Reference Manual and got some brief idea about what all the drivers (like wm8960.c, imx-wm8960.c, fsl_sai.c) are doing.
I checked the drivers by putting some debug prints. They were loaded properly. So, what should I do next?
