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?
Or I have to do beam forming to sort 8 channels out by custom application?
