1. We hope ADV7623 HDCP encrypted output, could you tell me whether only need to configure the two registers.

HDCP_DESIRED, TX Main Map, Address 0xAF[7]

HDCP Encryption enable

FRAME_ENCRYPTION_EN, TX Main Map, Address 0xAF[4]

HDCP Frame Encryption enable.

 

2.We use ADV7623, HDMI can't normal output voice, when the computer play songs, speakers is noise, computer stop play songs, sound box to stop shaking.
