Important: Under normal conditions the settings for de-embedder A and B
should be different, otherwise the audio will be repeated from the video
input.
With these controls, you can set the destination group for Embedder A and
B.
When set to Off, the embedder will be disabled.
Otherwise, the embedder destination can be set to a specific group.
The group for Embedder A must be different from Embedder B.
This control adjusts the audio delay +/- 4800 samples from the nominal
delay necessary to match the card's video processing delay.
Note: Negative values are limited to the amount that causes the delay to
reach the video processing delay, as the card does not have negative delay
ability.
This control allows the user to adjust the mode for the sample rate
converters.
Enable – Enables the SRC for PCM audio.
Bypass – Bypass the SRC. Should be used for non-PCM audio.
Auto – The module will automatically select enable or bypass on a per-
stereo-pair basis.
