Hi ,

    I'm testing i.MX6ULEVK wm8960 by aplay and arecord.  The images I used are the official demo of L4.14.98_2.0.0_ga and I have set the configurations for the board's mic. I could play the /unit_test/ASRC/audio.wav file.  But when I tried to record by "arecord -Dhw:0,0 -d 10 -c 1 -f S16_LE -r 48000 test.wav", the test.wav have captured nothing. How to deal with it?

    Hope your help. Thanks !
