With AXI-I2S Audio IP from Analog device, we managed to get some sound in Linux (although no sound with low level app). But there are some issues. It only plays the PCM file with 48k sampling rate properly.
We found some info in forum here https://ez.analog.com/thread/21167?start=0&tstart=0, I tried to add support for different sampling speed in driver but the result is the same, it only works at 48k sampling rate.
Do you have any idea if it is the limitation of the IP or other settings?
