The AP_OUT select AP_IN and audio-output as expected.
The TX select 1080p60 of RXA and video-output as expected.
TX AUDIO INSERTION select AP_IN and Audio InfoFrame,Channel Status,Clear AV Mute are output as expected.
In addition, ACR and AudioFIFO work as expected.(checked by Analyzer.)
But HDMI embedded sound is not output at all.(The indication of Analyzer is complete silence.)
What is the cause?
