Could you give some advices about the problem below?
Our project in called Limo Universal can't get any audio when plug with our DVD Player(DVD disk is ok,but CD not.).
The Universal use the ADV7480 as a HDMI sink device and DVD Player contains the ADV7511 is a HDMI transmitter.

At present DVD Player configuration:
Input audio:s/pdif (0x0A=10,0x0B=8E)(Max sample frequency is 48K)
N=6272 CTS=automatically (0x01=00,0x02=18,0x03=80)
Audio Sample Packet & Infoframe is enable (0x44=79,0x12=00)


Is our setting compatible with ADV7480?

What value of N&CTS is more proper for adv7480?


For the ADV7480:

How the adv7480 acquire the sample frequency?(Sample frequency is just 32k/44.1k/48k.)
Which register could indicate the input sample frequency is changed?
