I have a problem transmitting audio over ADV7511W, input to ADV7511W is verified, all I2S clk and data signals are correct at input, but we don't have nothing at output. We have situation where audio works on W2261VP Flatron monitor, we do not know how, but it does not work on any other sink. I am assuming that maybe audio configuration on ADV7511W is not done good, I would like someone to clarify me some config fields related to audio.
In ADV7511W Programming Guide page 69/190, as we input audio from I2S to ADV, for what MCLK ratio is used for? Do we have to use it, even we provide MCLK over our input I2S lines?
MCLK enable can be internally generated or available, does it mean that internally means that it is generated from HDMI clock, and is available that it uses MCLK we provide over I2S lines?
Video works fine, but no audio.
