AD9889B - audio Interface with SoC

we are using the ad9889b HDMI transmitter, in our Linux based platform.

Our SoC is having I2S audio interface.

We got the video display using the HDMI output, but no audio.


1. Our SoC-I2S interface signals are directly connected to the ad9889b's I2S interface, is that OK? or any Audio codec is needed between this interface?


2. In one of the DELL HDMI monitor, we did not get the video output, always. i.e. at some times the video is not displayed.

what could be a possible reason for that, and what are the check points to debug this issue?
