Then how about imx-ssi driver's support for mono capture? Does anybody succeed to do this? I try to capture an aux input into a mono wav file, what I get in the wav file is not correct. But when I try to record with "arecord -d 10 -c 2 -f S16_LE -r 8000 -t wav foobar.wav", the wav file is much closer to the aux input audio, although still not the expected result. Is it the same possible reason that affects mono channel capture?
