Tool/software: TI-RTOS
Hi ,Thank you for your help .
We use K2GEVM board to configature 4 PCM1864, The project we use is K2G_bf_rt . We use I2C0 and I2C1 to configuration .Some times there are problems .The log from console is as follows:

Audio Preprocessing Demo22
******************************************
This Demo Takes the Audio Input from 8 Mics from CMB
Runs the BF+ASNR+MSS+DRC Signal Processing Chain on Mic1 through Mic7
The Processed Audio Output will be Sent to Left Channels of K2G EVM On-Board Line-Out
The Mic8 will be Sent to Right Channels of K2G EVM On-Board Line-Out
Please Plug a Headphone to K2G EVM On-Board Line-Out
