Hi,
I have configured the I2S as it is shown in this topic and the I2S Output work perfectly.
Now, I'm testing the I2S Input and I've found some problems.
I'm trying a loopback between I2S_DOUT and I2S_DIN to test the I2S input.
When I try to use the arecord command there is an error:
arecord: main:828: audio open error: No such file or directory
Could you indicate how did you test the I2S input?
Thank you
PD: here are the output of the arecord -l and arecord -L:
root@OpenWrt:/# arecord -l
