Hello, All!
I have a problem.
I used board with ALC203, and once I have found strange effect: with stereo signal is recording, sometime left and right channels can be swap random.
I checked it 'arecord -f cd my.wav' - the same effect. I tried search reasom myself, but my skill in C not so good, exactly linux kernel.
What should I do next?
