I2S and PCM Audio on iMX6 Dual

We are working on an iMX6 Dual design and have three audio peripherals to connect:

* An HDMI Receiver with MCLK, BCLK, LRCLK and DATA output signals

* An I2S Digital Microphone with BCLK and WS in, DATA out

* A Wi-Fi/BlueTooth IC with PCM_CLK, PCM_SYNC, PCM_IN and PCM_OUT signals

 

We will be running Android as the operating system.

Question is: any recommendations on the best way or ways to connect the above 11 signals to the four audio ports - AUD3 to AUD6 - on the iMX6 Dual?

Hi Stephen

one can check AN2628 Programming Audio Applications, basically it is valid for i.MX6 AUDMUX too
