The Audio control menu is used to configure the on-board audio sample rate converters and the internal
audio delay block. The Audio menu is also used to enable and disable the four internal audio embedders
and to specify C bit processing modes. SRC status, Audio Delay, Video Delay are also monitored and
reported in the Audio menu. Sections 7.14.1 to 7.14.2 give detailed information about each of the menu
items.
Any changes to the audio settings will cause a momentary interruption on the output
audio.
7.14.1. Audio Control
7.14.1.1. Audio Delay
This control adjusts the audio delay +/- 350.00 ms. This delay is relative to the delay that the module
automatically inserts to match audio path and video path delays.
Note: Negative values are limited to the amount of video delay; the card does not have
negative delay ability. Video delay can be added in the Video Tab in order to achieve a
greater negative audio delay. See Section 7.1.1.10 for details on how to add additional
Video delay
