Do I need to check the registers in order to output HDMI audio with the ADV7625?

Before the screen is displayed, the address 0xAF of Tx is set to 0x16 and it is in HDMI mode.
Then, sound may not be output in some cases.

When the HDMI mode is set after the screen is displayed, sound is output.

How can I change the HDMI mode to output audio before the screen is displayed?

 

Please teach me.

 

Best regard.
