Copy call back is getting invoked for sterio mode with below command

arecord -c 2 -f s16_LE -r 48000 -t wav test.wav

But when I tried to create separate files for both the channels using
below command, copy call is not getting invoked.

arecord -c 2 -f s16_LE -r 48000 -I test1 test2

Please help me out. I want to create separate raw files for both

Thanks and regards,

Just give two file names.  Please note that this always results
in raw files.
