Is audio embedded in local HDMI output?

I need to split audio from video signal to external amplifier. I want to use an audio extractor on local HDMI output. Will it work?

VE3912T has local HDMI output and audio embedded in it.

If the input sources such as VGA with analog audio, HDMI with audio signal and DisplayPort with audi signal, the local HDMI output of VE3912T with audio signal.

Users can use an audio extractor to split audio from video signal like VC882.
