I am working of a project that need to apply external I2S audio to ADV7623 and output via HDMI TX section. The connection are: MCLK input to PIN68(MCLK_IN), SCLK to PIN69(SCLK_IN), LRSCLK to PIN70 (AP5_IN) and AudioData to PIN76(AP1_IN).
I read the section 8.4 of the Hardware Manual, but still not work it out. External audio still can not apply to HDMI . What configuration i need to set for that?
Further more, If the RX HDMI also contain audio, how can I de-select the HDMI audio and apply external audio and output via HDMI?
Thanks for your time.
