"--separate-channels" option only allows two files for two channels. Interesting thing is plughw:0,1 -c 1 works only for one pin input (two channels).
plughw:0,1 -c 1 complains overrun for 6 channels (3 input pins) input.

List,
I have 8 channels of hdmi input and one channel output
on my board.
When arecord -f dat hdmi-rx.wav to store 8 channels
data, aplay -f dat hdmi-rx.wav releases noise.
Ia there any way arecord stores each channel data to 8
different files?
check out the "--separate-channels" option for arecord. see if it meets your needs.
Or I have to do beam forming to sort 8 channels out by
custom application?
Thanks.
