setting for ADV7511 ARC(audio return channel)

My setting for ARC is simple:

* 0xDF[0] = 1   ; ARC power up

* 0xDF[7] = 0   ; select Common Mode ARC Input


HDMI cable is connected to HDMI port(ARC supported) of TV. But I cannot detect any signal in SPDIF_OUT pin.


Since ARC communication between TV and ADV7511 is controlled through CEC, do I have to do some settings for CEC in ADV7511?
