I'm having difficulty adding analog audio from IN1_L & IN1_R to HDMI using the ADV7850 and ADI HDMI drivers. Adding audio to an analog RGB signal for HDMI output works fine but when I attempt to add it to an incoming DVI or HDMI signal I don't get the analog audio at the display.
From an analog audio perspective what should I be varying between an incoming RGB vs HDMI signal for HDMI Tx?
What mode should the driver be running to process incoming DVI / HDMI and pair it with analog audio. Repeater? Receiver?
Can it replace the existing HDMI audio with that analog audio or does the incoming signal need to be DVI?
We're hearing audio "pops" on changes between RGB and HDMI. Any suggestions to alleviate this would also be appreciated.
