Hello,

 

I am working with Ad9889B HDMI Transmitter. I am able to see the video on TV but not able to hear audio from TV.

 

My audio path is as below.

 

ADV7441A HDMI receiver capture video and audio and give that video and audio to AD9889B HDMI transmitter. Here Video is 16bit 422 YUV format and audio is I2S 4-channel, 16 bit word, right justified format at 48Khz frequency. I probed  audio data on AD9889B, it's comming fine. But some how AD9889B does not able to transmitt audio on TV.

 

Here I am sendig I2C configuration dump for AD9889B.
