I have an ADV7513 in our system and I am having a slight issue trying to get I2S audio to be heard on the HDMI panel.  Currently we are feeding 16-bit YUV data for 1080p at 148.5Mhz. and we get clean video sync up on the HDMI TV.

The audio format I am feeding to ADV7513 is 24-bit I2S format at 44.1kHz.  I'd like to know if the below register programming for the ADV7513 is correct.  Thanks.

MCLK = 16.934MHz.

SCLK = 2.116.8Mhz.

LRCLK =44.1kHz.
