Hello Dear Team,

I have a customerized board with jetson Nano module,
its I2S3 interface connected to a HDMI-IN chip I2S pins. I checked on thoes pins, the wave of in, fs, clk are all ok. But i cannot get any voice from the command command:
arecord -D hw:1,1 --buffer-size=19200 -r 48000 -f s16_le -c 2 -t raw | aplay -D hw:0,3 --buffer-size=19200 -r 48000 -c 2 -f s16_le -t raw
here, the device hw:1,1 is connected I2S3, and hw:0,3 is connected to hdmi hda codec. i confirmed hw:0,3 is working well by aplay a wav file alone.
here is some device tree content about voice for this I2S3.
