AEC on TLV320AIC3254 with Analog IO

Hi,

we are trying to evaluate your echo cancellation algoritms on TLV320AIC3254EVM-U to build a custom board. In detail we are interested in analog input (using a line in, not directly connected to a microphone and using the same jack to provide far end input on a channel end near end input on the other channel) / analog output (near end output on a channel and far end output on the other channel). I started with the example process flow AIC3254_AnalogIO_AEC_32_NR_Mux. I tried to edit the SystemSettingCode in the framework design properties to adjust the right audio paths but it didn't work. The documentation never refers to analog IO only I2S. Can you give me some suggestions? Thanks in advance.
