Multichannel audio on ADV7619

On one of our boards, I'm busy implementing an HDMI receiver chip ADV7619.

Stereo Hdmi Audio works fine.

If I switch to 7.1 channel Hdmi Audio, I see the channel mode bit : AUDIO_CHANNEL_MODE, Addr 68(HDMI), Address 0x07[6] is changed to 1 (8-channel audio), but data is only present on the first data line.

 

I don't find any mute or enable configuration for the other lines.

 

What registers are influencing those other lines ?

 

PS when Muxing the AP lines, I can see the data muxing so there is no hardware issue).

 

Br,

 

Thierry
