Dac Configuration Area; Routing - Epson S1V30000 Series Application

DAC Configuration area

The DAC configuration area allows configuration of the target's output audio. This must
be done before using any of S1V30xxx's applications which output audio.
The DAC Config button is used to configure S1V30xxx's audio hardware with the selected
parameters from the DAC Configuration area. Clicking this button causes an
ISC_AUDIO_CONFIG_REQ message to be sent to the target.
The following sequence of messages should be displayed to signal successful configuration
of the audio.
If this is not the case please refer to the trouble-shooting guide.
