I have question about I2S SCLK frequency of ADV7614.
When the play button of sound of HDMI source system is not pushed,
the HDMI stream does not include Audio data, N/CTS (that has Video data though).
When the HDMI comes into ADV7614, and I2S output is enabled, how the I2S SCLK frequency is calculated?
Is the frequency unknown or unstable?
