Facing issues with getting any sound at all from the MIC out on I2S; I am wondering if my configuration for the MIC path is correct.
I can play back sound from the PCM controller fine, but I am not getting any sound from the codec to the PCM controller (controllerdevice have also been tested with I2S configuration on controller and codec without any change in behavior).
I have verified the MIC connection itself by routing from MIC1 to Left Speaker Mixer directly and the audio signal is going through fine that way, but if I try the loopback mode to connect ADC output to DAC input, no signal is getting through.
And I also do not get any signal through if I use the sidetone option.
This makes me wonder if I have missed anything in the configuration or if something may have happened to the codec itself.
I am using the EVKIT software only to help me with the configuration and do not have the actual kit.
