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?
Regards, Jie

Yes, it seems to be this reason that causes problem. When I playback a stereo wav file(8kHz,16bit, stereo), everything goes well.But when trying to playback a mono wav (8kHz,16bit, mono)file, problem stills exist.
What's the possible reason for incorrect handling of mono file? How to solve it so I can playback mono file correctly?
The imx-ssi driver does not support mono-channel playback. I've also looked at this a bit but couldn't quite figure it out. Maybe Sasha (cc'ed) can give some pointers?
