HDMI Rx: About the behavior of audio output pin during Audio mute on

Hi all

 

We are in the design of equipment using the HDMI-RX device(ADV761x).

I have a question about the behavior of the Audio output pin in order to design an FPGA to be connected to the HDMI-RX device.

 

For example, if use the ADV7612, HDMI-map 0x1A [4] "MUTE_AUDIO" was set to 1,

regardless of the output format(such as I2S and SPDIF), only the output data becomes 0 (= mute).

 

In other words, the Audio signal output to continue, it is sending a silent data.

Is it correct in that understanding?
