We have created a device that utilizes the ADV7627. We use the 5 HDMI inputs to autoswitch, and I know that you need to force the Hotplug Assert each time someone reconnects. But what happens on your design is although the video will switch to another input, the audio never follows. The audio will just continue playing on the source device and the Television will have no audio; just video.
Is there a way to force audio to reassert?
