1)      I am using theboard connected only to my hdmi source. I have HDMI audio being sent to the board, but I am not able to see any infoframe audio packets. I was told (https://ez.analog.com/message/289896?commentID=289896&et=watches.email.thread#comment-289896) that I would be able to see the audio checksum in this, but on my development board I am only seeing 0’s in the infoframe data tab. I am using the EVP Evaluation Software 1.5.2 that was available to download with the development board.

2)      Is the development board going to need any changes if I add in the audio output components to the board? I had originally though that from all the documents on the kit that it would have the audio section populated, but after getting it in I have realized that it was unpopulated. So now I have had to order in the needed parts to get the board working as it was shown in the evaluation board documentation. I have software version installed on the board.

3)      Is there any easy way to determine what parameters are being sent to the ADV7611 on the development board starting at power up?

4)      Where can I find the edid that is being loaded into the ADV7611 when no monitor is connected.
