Audio alsa capture: IIS is currently being supported by McAsp?

Greetings,

In our usecase, audio data will be from an externel HDMI Rx together with video data.

I am using ezsdk5.04 and working on a custom dm8148 board.

My goal is developing our own alsa capture driver, so later we can use Gstreamer to process audio data.

I checked the TI81XX_Audio_Driver_User_Guide and did not find any info related to the IIS.

Just wondering, whether IIS protocol is already supported by current McASP dirver?

 

Regards,

Jun
