I have used the pre-built image on i.MX6ULL EVK board and need to test audio loop-back on wm8960 audio codec.
But I failed to test it and after that I gone for the capture operation using below command.
"arecord -D hw:0,0 -c 1 -f S16_LE -r 32000 sample1.wav".
So, using this command .wav file is created but it captured nothing while I palyed it (also test that file in audacity).
I also follow all steps from this thread : "arecord aplay loop-back test in iMX6ULL evk board " and failed to capture audio.
It is very helpful if you provide solution for this issue.
