My customer would like to know the internal audio delay time( mimimum ) from HDMI to I2s or SPDIF output on ADV7842.
This question is not for mute function. This question is internal audio delay time in ADV7842.
According to our HW manual of ADV7842, we can see the following description.
For best audio muting performance, the following settings are recommended
when the audio sampling frequency of the audio stream is greater than 48 kHz:
( Set AUDIO_MUTE_SPEED to 1 )
Set MAN_AUDIO_DL_BYPASS to 1
Set AUDIO_DELAY_LINE_BYPASS to 1
Probably, I think the bypass of audio delay line is the minimum delay time in ADV7842. But I am not sure actual delay time( msec ).
