We are trying to config sai1 to sample 64mic audio data, but fail.
1>each sai-rx interface connects 2 codecs, each codec connects 4 mics.
2>using sai1 rx0-rx7, total 8 ports with TDM mode, to sample 64mic.
3>using tinycap tool to sample, but is failed and showed below:
64mic: ./tinycap rec.wav -D 0 -d 0 -c 64 -r 48000 -b 32 -p 384 -n 4
32mic: ./tinycap rec.wav -D 1 -d 0 -c 32 -r 48000 -b 32 -p 384 -n 4
