Hi,
Copy call is working, Thanks for inputs.
When I tried to record using arecord "arecord -d 10 -c 2 -f s16_LE -r 48000 -t wav test.wav" sterio mode of recording works.
If I want to record both channels in separate files, what command should be given to arecord, I am not clear on -I option. Do I require to change my driver.
Thanks and regards, Kshemanth

Yes, I am not clear on what should be returned in pointer call back. From my understanding we have return available frames in buffer.
No, it has to return the position in the buffer after the most recently captured sample.
My ADC doesn't have buffer so, I maintain a ring buffer of 2 periods. ... .periods_min = 1, .periods_max = 2,
You need periods_min = 2.
