I'm using an eval board of ADV7623 Rev.D.
With a usb2IIc interface.
1. By default, there are audio on optical output and audio + video on TV.
2. I want audio input from the optical input port, so I connet an AD + optical out box to the optical input port. And there are signals on K13 position A.
3. K13 in position A.(do as the guide says.)
4. After power up nothing happens.
5. Probe U41 ,find that RMCLK,LRCLK,BCLK SDOUT they all have no signals at all.
What is the problem, can anybody help? Thanks!
