Our product used adv7441a(170 with hdcp) to decode hdmi. The port A and port B shared the same internal EDID. With the same DVD player, port A can get the correct video and audio, but Port B get video only. Port B indicate that it is DVI mode ,not HDMI.
I have set the register(0x0@HDMI) to switch PortA and PortB. The result is the same when i try many different EDID. The source of video is 720p50 from dvd.
Please help me, thanks a lot!
