I'm using ADV7842 to conenct to my Digital box's HDMI output with LPCM-DUAL. audio and 1080i video.
This HDMI output works well on TV.
When I connected it to ADV7842, after I ran the initialization script for HDMI 1080i mode. I do see the correct video output SDR20bit.
But I can't see the I2S audio signal from bus. And when I check the register
"HDMI_MODE, Addr 68 (HDMI), Address 0x05 (Read Only)", it shows me that the input has been detected as DVI mode.
I guess that this is the reason that I can't get correct audio (i2s) output.
