I managed to test arecord and it works with the following as follows: 1. Run alsamixer and select LINE_IN in the Capture element 2. Record with the following command line: arecord -D hw:0,1 -d 10 -f S16_LE -r 44100 -c test.wav 3. Then listen test.wav on your PC or in your board itself. The sequence above works fine. Anyway, I will submit the patch I sent earlier as it prevents the system to get unresponsive.
