Dear Dir,

On my ADV7623 system,

I have already defined EDID support DTS-HD,Dolby TrueHD and

OVR_MUX_HBR is set to 1,

MUX_HBR_OUT is set to 0,

I2SOUTMODEis set to 0x0

But when ADV7623 received HBR audio, the output data on four I2S line are not continuous, Pls see the attached file.

Can you tell me why?

And, when I rebuild the data on I2S0~I2S3, I found it contain the header word(such as 0x64582025)  correctly. see the attached file "buf.h", The same of the waveform show,there are also many many 0x00000000 data.

Why the data not continuous?
