ADV7480 without audio output

Hello

In my project,I use the ADV7480 as the hdmi sink.But I can't get any audio .The video is ok.

I found that the LRCK=17.47k BCK=1.12M

For question:

1.Is it the problem of source's CTS&N value(I use the adv7511 as a HDMI source)?
2.Would you give some scripts setting of ADV7480?
